Postcards: Glass Beach

While waiting for a battery to be replaced in my helicopter’s GPS, I got into a conversation with one of the avionics shop guys about my planned driving route along the California coast to get home. He immediately mentioned Glass Beach near Fort Bragg and even showed me a web page about it. 

I visited on Tuesday. It’s a neat little cove on the Pacific where sand-smoothed broken glass washes ashore, forming a beach with more glass than sand. 

Lake Berryessa and the Glory Hole

Not something you see every day.

I spent a few weeks in the Sacramento area of California — as I have been since 2013 when I brought my helicopter there for its first frost control contract — in late February and early March. I’ve gotten to know the area pretty well over the past five years and as I continue to explore new places, I also return to the old ones. Lake Berryessa, the largest lake in Napa County, is one of these places.

I first discovered it during a drive up Putah Creek, starting in Winters, CA. From there, I made a stop at the Lake Solano Campground (which I eventually stayed at for the first time this year) and noted its crazy collection of peacocks. Farther up the road, I passed numerous parking areas for fishing and hiking and picnicking. Still farther, the road crossed the creek, wound up a hill, and passed the Monticello Dam, which holds in the waters of Lake Berryessa. Penny and I have hiked in various places along the shore, driven much of the west side’s shoreline, and even flown over it numerous times in my helicopter.

Aerial View of Lake Berryesssa
An aerial view of Lake Berryessa, shot with a GoPro on my helicopter back in March 2014. The water was very low.

For the first four years I’ve been in the area, the lake level was low — very low. This isn’t surprising given the serious drought that affected nearly all of California. All of the lakes I flew over were low. But this year things were different. This year, all the lakes are full, nearly full, or even — in some cases — overflowing. Lake Berryessa is one of the lakes with too much water.

Man-made lakes — basically, any lake that holds water in with a dam — usually have flood control features built in that guide excess water safely out of the lake and into a receiving stream or river. This is normally done with the use of a spillway that can be opened or is automatically utilized before the water level reaches the top of the dam.

Spillways come in different styles. The most common is a sort of water chute that excess water flows down, away from the dam. Most dams have this kind of spillway. The Oroville Dam, which has been in the news a lot lately, has spillways like this, one of which was severely damaged by floodwaters.

Another less common type is an open bell mouth spillway. That’s the type at Lake Berryessa. It’s a round concrete hole not far from the road and the dam. From Wikipedia:

Near the dam on the southeast side of the reservoir is an open bell-mouth spillway, 72 feet (22 m) in diameter, which is known as the Glory Hole. The pipe has a straight drop of 200 feet (61 m), and the diameter shrinks down to about 28 feet (8.5 m). The spillway has a maximum capacity of 48,000 cfs (1360 cms). The spillway operates when there is excess water in the reservoir; in 2017 after heavy rains it started flowing, for the first time since 2006.

Monticello Dam w/Glory Hole
In looking through my archive of photos from 2014, I found a GoPro photo of the dam from the air that clearly shows the Glory Hole when it isn’t in use.

It was in the news in February because the lake had finally filled, after 11 years, and water was flowing into the Glory Hole. Of course, I had to go see it. So when I got the helicopter into California and needed to a “maintenance flight” to check a few things, I headed over there. Sure enough, water was flowing into the hole and a small gathering of people along the road were looking in. I flew by a week later and the water was still flowing in.

I wanted to see it again from the ground, so I returned on Saturday. By that time, Penny and I were on our way home from nearly four months on the road so I had the Turtleback on my truck. Once again, I’m so glad I downgraded from my big fifth wheel; parking in the very crowded parking area was remarkably easy.

There were a lot of people there. It was, after all, Saturday and the Glory Hole had been on the news quite a bit. It made a good, easy, and free point of interest for sightseers.

Glory Hole from the Road
The Glory Hole, photographed from the road. That’s the dam to the right. The water is pretty close to the top.

Penny and I joined the crowd and walked along the road for a good look. The chain link fence made it difficult to get a good photo. The hole is right next to the road and pretty much fills the camera lens. But I did my best.

A guy was out there with a Phantom 4 drone so I decided to give my drone (AKA flying camera) a shot when he was done. I went pack to the truck, put Penny inside, and pulled out my drone. Within about 5 minutes, I had it all set up in a clear area between parked cars and the fence downstream from the dam. When I was sure the other drone had landed, I launched mine.

Understand that I’m still learning how to use my Mavic Pro. I’m also very careful. Immediately after launching, I took it up over the lake, away from people. Then I captured some still and video shots of the Glory Hole from the air, including a short pass where I flew directly over the hole with the camera pointing straight down.

Glory Hole from the Air
I really don’t know why the water looks so green in this shot. I don’t think it’s the camera. It must be something to do with the light.

I tweeted the video clip and got a lot of positive feedback about it. I also got a request to contact the folks at a video licensing company who want to represent me on the resale of the clip to news other media organizations. I’ll all for that, provided my FAA Commercial UAS Pilot certificate has come through; it’s not legal to sell drone photography without it. Need to get home and check my mail to see if the paperwork is there; I applied back in January so I should be good.

I need more practice using my Mavic and I intend to get some on my way home. I had it out again this morning from my campsite at Bodega Bay. I’m hoping to put together a little montage when I get home and share it here on the blog. Stay tuned.

Snowbirding 2017 Postcards: Salton Sea Birds

A few photos from my visit to the Salton Sea.

While I was traveling around Arizona and California this winter, I had more than a few opportunities to do some photography. At the Salton Sea in California, which I visited in mid January, I spent much of a day photographing the birds along the salty water or walking on the barnacle beach. For most shots, I used a 70-300mm Nikkor lens on my Nikon D7100 DSLR. I thought I’d share the best of them in a quick “postcards” blog post here.

I suppose I should say a few things about the Salton Sea. It’s a strangely beautiful, highly saline lake in the middle of the desert in southern California. It’s surface is roughly 235 feet below sea level. It was formed years ago when the Colorado River flooded and jumped its banks, pouring water into the low-lying desert for about 16 months. There are no outlets; the lake is fed by irrigation runoff and kept level by evaporation. The salt level rises steadily. The beaches are not sand; they’re barnacles. The place is home to more than 300 species of birds, many of which are migratory. The visitor center has a lot of good information with friendly, knowledgeable staff. I would definitely visit again. You can learn more on Wikipedia and the Salton Sea Authority website.

Here are the bird photos. One of these days, I might get back into this blog entry to add captions with the names of the birds. If you know any that aren’t named here, please comment to let me know and I’ll add a caption.

Snowbirding 2017: A Trip to the Racetrack

And its fallout.

After a night spent at the Mesquite Springs Campground near the north end of Death Valley, I got an early start on my trip to what’s known as The Racetrack. It’s basically a dry lake bed in a valley on the west side of the park where large rocks “mysteriously” move by themselves across the flats. I put mysteriously in quotes because it’s pretty obvious that the rocks are moved by strong winds when the silty playa is slick from a heavy rainfall. But heck, it gets people out there, right?

The visitor center had warned me that the road was only appropriate for vehicles with good tires. Apparently more than a few tourists have been getting flat tires on some of the more rugged roads, which really aren’t intended for their Priuses or even their city-slicker Jeeps with junky car tires. I assured the ranger that I had all terrain tires on my truck and that they were only a year old. Still, she got me worried about my tires all day and I knew I’d never get AAA out to change a flat, even if I did have a cell signal to call them. I wondered if I could get the spare down from where it was hung under the truck if I needed to.

I left at just after 6 AM, eager to get to the Racetrack in the best light, but not interested in making the estimated 2-1/2 hou drive in the dark. It was still dark in the campground as I pulled out of my spot, leaving the Turtleback behind, but dawn was more than a hint to the east. The bright waning gibbous moon made it possible to pull out with only my parking lights on so I wouldn’t disturb other campers.

Ubehebe Crater
Here’s a tourist photo I shot of Ubehebe Crater the day before.

It was chilly so I turned on the heat for my seat and Penny’s and cranked the heat up a bit. I headed out to the main road, then turned left and followed the pavement all the way to Ubehebe Crater, which I’d visited the day before. Then I made the right turn off pavement, onto the gravel road I’d be following for 24 miles.

Whiplash — For a Reason

The road was completely washboarded and I bounced along it, trying but never quite succeeding to pick a speed that smoothed the ride. I tried 10, 15, and even 20 miles per hour. No joy. I drove with one hand, holding my coffee, in a travel mug up with the other so it wouldn’t spill out of the drinking hole in the cap. That bumpy. Penny alternately stood and sat on the console between the two seats, somehow not falling off.

The road climbed as the sky lightened. It was pretty straight and very narrow — maybe 1-1/2 cars wide? There were few turnouts. I’d considered, the previous day, making camp somewhere along the road instead of back in the campground, but I was glad I had decided not to — there was nowhere to pull off to camp. The grader, which likely worked the road at least once a decade, had left tall dirt curbs on either side of the roadway. There were very few places even wide enough for two cars to pass, let alone for someone to camp.

That didn’t stop someone in an SUV. They were parked nearly half in the road and had likely camped out there overnight. No one stirred in the vehicle as I slowed to inch my way around it.

As the road climbed, the vegetation changed and the outside temperature got colder and colder. Cacti and greasewood bushes gave way to Joshua trees. My outside air temperature gauge got as low as 33°F. I saw frost.

Time passed. It got lighter and lighter. Soon first light touched the tops of the mountains around me. I continued bumping up the road, never quite getting comfortable. Not another soul was in sight.

Sign at Teakettle Junction
The sign at Teakettle Junction.

After nearly two hours, I’d gone 18 miles and arrived at Teakettle Junction, which is actually a named place on my map. But that’s about all it is. It’s a crossroads with a turn off for someplace called Hidden Valley. A sign decorated with a variety of hanging tea kettles stands at a triangle in the road and points the way. A couple with a big dog in an SUV were camped there, which surprised me because I thought camping wasn’t allowed at the Junction. But, at the same time, it wasn’t as if there was anywhere else to camp.

When I got out to take the photo of the sign, I smelled something I don’t usually smell around my truck. Some kind of hot oil or maybe transmission fluid. I took a quick walk around and looked underneath to see if anything was dripping. Nothing looked wrong and the truck sounded fine. So I got back in and continued on my way.

I saw Racetrack Valley minutes later. The main feature, besides the very large dry lake bed, was an island of rocks near the north end. This is what was referred to as The Grandstand. Oddly, I’d never seen any photos of it and it was a heck of a lot more interesting to me than a few moving rocks. It was obviously volcanic in nature — the whole north end of the park shows a lot of evidence of volcanic activity — and wasn’t very large. It reminded me a little of Wizard Island at Crater Lake.

The Grandstand
The Grandstand looks like an island in the middle of the dry lake bed.

Melted Shock
When I break something, I break it for keeps.

We reached a very small parking area with an interpretive sign just abeam the Grandstand. I parked the truck. Again that smell. What was leaking? I walked around the truck, now looking into the wheel wells. That’s when I saw that one of my front shocks was stripped bare of its protective cover and the other was leaking like a sieve.

Great. Well, I guess that would explain why I felt like I had whiplash.

There was nothing I could do about it, so I got a few things together and walked out onto the dry lake bed with my camera. But before I tell you more about my visit, I need to take a break and get something off my chest.

A Word about National Parks and Vandalism

National Parks are among America’s greatest treasures. They set aside special land to showcase some of the most amazing things that can be found in our country: geology, topography, history, wildlife, etc. They are managed by Federal employees who work hard to protect not only the parks and the wonders inside them, but the people who visit those parks. Anyone who tells you otherwise is, quite simply, an uninformed/misinformed idiot.

Every park has rules. Unfortunately, they’re necessary. For some reason, people think it’s okay to litter, or let their dogs shit on trails, or carve their initials into the rock beside petroglyphs 1000 years old. Most of the rules in a park protect the park, although a few also protect the people who visit.

One rule in Death Valley is that off-road travel is prohibited. This is pretty simple stuff: if it isn’t a road, you shouldn’t drive on it. If you’re not sure whether something is a road, it probably isn’t so you shouldn’t drive on it. If something was a road once and isn’t a road anymore, the Park Service has very considerately placed signs letting you know that it is not a road and you shouldn’t drive on it.

This rule protects the fragile desert, its plants, and even its rocks from the affects of a 2000-pound (or more) vehicle’s four tires as they make contact on the ground.

The Racetrack is one of the places where the staff at Death Valley National Park has placed signs making it pretty clear that you shouldn’t be driving anywhere off the road. A dry lake bed is not a road. It doesn’t even look like a road. If you think it’s a road, you probably should not be driving anywhere, let alone in a remote area of a National Park.

I had been warned by a friend who truly loves Death Valley that the Racetrack had been vandalized by some — pardon my language — fucking inconsiderate moron driving a vehicle on it, likely when it was either wet or damp from a rain. Tire tracks now criss-cross the dry lake bed, in some places deeply embedded into the surface. It rains very seldom in Death Valley, but it had rained earlier in the week. Still, the tire tracks remained in the otherwise pristine surface. It could take decades for them to disappear.

That means that the Racetrack’s otherwise pristine desert playa environment has been destroyed, possibly for generations of visitors.

Vandalism at the Racetrack
I took photos to document the tire tracks. I want everyone to see how this area was ruined by a vandal who thought it was fun to drive around where signs clearly told him not to.

Thank you, selfish asshole fuck-head.

A sign where I parked also asked visitors not to walk on the surface of the playa when it was wet. Well, some asshole had done that, too. Fortunately, he was either a lazy son of a bitch who didn’t walk very far or his brain belatedly connected with his feet and he realized he was leaving somewhat permanent footprints. The surface was dry when I visited, but the footprints remained.

Is it that difficult to obey the rules? Will it truly ruin your visit to not vandalize the terrain while you’re there? Are you so important that you don’t have to worry about whether your fun will ruin a National Park’s natural wonder for the thousands of other people who might not want to see it ruined?

If you answered yes to any of those questions, go fuck yourself and stay the hell out of our national parks.

You want to drive around on dry lake beds? Go to Nevada. There are a shit-ton of them there that no one cares about.

Glad I got that off my chest.

My Visit to the Racetrack

Textured Mud
I love closeup views of surfaces textured by nature. This was near the edge of the dry lake bed.

I walked onto the lakebed carefully, making sure I wasn’t leaving any footprints. (I didn’t.) The surface was bone dry with a flat textured or cracked surface that was actually quite interesting — if you’re interested in textured or cracked mud, which I apparently am.

There were a few rocks on the north end where I was walking; the interpretive sign had mentioned that the moving rocks were mostly at the south end but, after 24 miles, I didn’t feel like driving another 3 miles (each way) in my mobile bouncy house to see them. I don’t think the rocks I saw were moving rocks, but who knows?

A Not Moving Rock
I don’t know if this was one of the moving rocks. It certainly wasn’t moving when I saw it.

Beach
Where the Grandstand’s “island” met the playa reminds me of a beach.

I walked three quarters of the way around the Grandstand, then climbed up one side of it and crossed the rocks in an area where crossing was easy. I liked the way the gravel rock of the Grandstand’s “island” formed a sort of “beach” where it met the dry lake bed around it.

Rocks on Grandstand
A close-up of the rocks on the Grandstand.

I used my binoculars to look down the lake bed where something shiny was just beyond the surface. Three vehicles, one of which had a very small camper on it. They probably didn’t have broken shocks and were looking at the moving stones.

I headed back to the truck. In need of a bathroom break, I was very disappointed by the lack of cover in the surrounding desert. Still, with the closest people at least two miles away, I crossed the road and walked a bit away from it before taking care of business. I suspect I wasn’t the only one who’d used that particular area for that particular purpose. But why hadn’t the others taken their paper with them? Inconsiderate.

I climbed back into the truck with Penny, started it up, and turned around. We began our long bouncy ride back to camp.

The Aftermath

Two of the vehicles that had been at the south end passed me before I left. I got in behind them. There was some position juggling and I became the middle one. I was glad; if my truck decided it wasn’t going to go any farther, at least I could hitch a ride out with the guy behind me.

We passed about a dozen inbound vehicles on our way out. About half were rental Jeeps. In most cases, I pulled up off the side of the road with my left wheels, leaving enough space for people coming from the other direction to get through. Just once someone moved over for me.

One of the cars was a compact. Maybe a Toyota? It was near the beginning of the road. As they passed, I asked them if they were sure they wanted to make the drive. “Does it get any worse?” the older man at the wheel asked me. “A little,” I said. “It certainly doesn’t get any better.” They kept going.

I was almost surprised I made it without a wheel falling off or something. It took nearly three hours. I don’t think the shocks got any worse.

I was pretty glad to hit pavement. But not when I hit 65 miles per hour. That’s when a front end wobble kicked in. Shit. Had I broken something else?

Up at the Grapevine Ranger Station — which didn’t have any rangers in it — my cell phone worked. I parked and did some research. Within 20 minutes, I’d made an appointment to get the shocks replaced in Pahrump, NV, a two hour drive back towards Las Vegas. It was the biggest town around. The repair shop said the parts would be in at 8 AM and I said I’d be there waiting for them.

Back at the campground, I found a man who had some experience with heavy equipment and had him look at it. My question: could I put my camper back on and take it as far as Stovepipe Wells or Furnace Creek? At first, he said no. But later he came to my campsite and said that if I took it slow I might be able to make it to Furnace Creek. That was only an hour from Pahrump and it would save me a lot of driving the next day. So I loaded it up and made the move. I was fortunate to get one of the last three campsites at Furnace Creek.

I treated myself to a fine meal at the Furnace Creek Inn. I really need to stay there one day.

In the morning, sore as hell from the previous day’s ride, I bounced the 51 miles to Pahrump, using cruise control set at 64 mph. I had a nice breakfast at Mom’s Diner while the folks at Pete’s Auto Clinic replaced all four shocks. The 65 mile per hour wobble was gone when I headed back to pick up my camper and exit out the other side of the park.

Hours later, my truck left Death Valley westbound under its own power for the first time. My camper was on top. My 7-month vacation was officially over.

Snowbirding 2017: Astrophotography

Practice makes perfect. I’m practicing.

I have more than the average amount of free time in my life and I like to put it to good use doing and learning things. Last September, I took an astrophotography class at the North Cascades Environmental Learning Center. You can read about the class and see some of the photos I took during our field trip in this blog post.

What I learned about shooting the night sky is that it’s very easy to do if you have the right equipment. Fortunately, I do: a DSLR with full manual mode, a very wide angle (10mm) lens, and a sturdy tripod. The hardest thing to do is to find skies dark enough to see enough stars to make the effort worthwhile.

We had dark enough skies in the North Cascades, despite ambient light from the nearby dam and occasional passing car. I don’t have dark enough skies at home, though — the glow from Wenatchee is surprisingly (and disappointingly) bright. And although I camped at more than a few places that should have been dark enough for night sky photography, most weren’t.

Or if I found a place that should have dark enough skies, the sky was overcast while I was there. Or the moon was in the sky, illuminating it so only the brightest stars showed.

Cibola
I like this shot of my RV parked on the levee along the Colorado River. I had to crop it square to get rid of the light from the town of Cibola, which is still in the shot.

I did have some success back in January when I camped out along the Colorado River near the Cibola National Wildlife Refuge in southwestern Arizona. I shared one of those photos in a blog post about the campsites I’ve been finding.

The one I didn’t share was a bit more challenging and I’m not sure if I successfully pulled it off. (Maybe you can tell me?) The bright point of light in the sky is Venus. I wanted to catch its reflection in the Colorado River, which I did. Unfortunately, although it was long past sunset, there was still a bit of a glow to the west. I think it’s from towns and homes off in the distance, but who knows?

Venus Reflected
It’s nearly impossible to include the horizon in a night photography shot without some sort of glow from terrestrial lighting.

I got a chance to practice again in Death Valley National Park, on my third night in the park. The first two nights were too cloudy and the moon was nearly full anyway. But the third night offered a window of opportunity between the end of twilight and before the waning gibbous moon came up. I was parked in Greenwater Valley with some mountains behind the camper. It was very dark outside and the sky was full of stars. I took eight shots. I think these two are the best.

Death Valley Night Sky
This was my first shot of the evening with the camera pointed pretty much straight up. It features the Milky Way with the Pleiades near the center and Orion’s Belt almost cropped off the top.

Death Valley Night Sky
In this shot, I pointed the camera up above the mountains behind the camper. You can see the big dipper just above the horizon. Once again, there’s the glow from something out there; it’s not the sun because I was pointed east.

I think photos are more interesting with something in the foreground. The one with my camper works for me. So does the one with Venus and its reflection. I guess the challenge is going someplace with something interesting to frame in the foreground and possibly “light paint” it with a lantern or something. It wouldn’t take much. The only light in my camper in the above shot was from a single tea light candle burning on the dining table inside. It looks as if I have multiple lights on!

I enjoy doing this, although I admit I’d likely enjoy it more with companions on the same sort of mission. Because my remote shutter release doesn’t work — I think it needs a new battery (again) — I have to use the camera’s self-timer as a shutter release. That adds 10 seconds to a 30 second exposure with about 30 seconds of processing time before an image finally appears. A lot of time standing around by myself in the dark. The field trip I took at the North Cascades class was a bit more of a crowd than I like, but at least it kept things interesting.

I hope to get at least one more chance to experiment with this kind of photography on my trip, but I’m not sure when. Most of my remaining destinations are not well known for their dark skies. I’ll see how I do.

Return to Burro Creek

And another [safer] flight under the bridge.

Back in November 2014, I blogged about the time I was in a helicopter that flew under the Burro Creek Bridge on Route 93 at Burro Creek. It was probably on my mind back then as I was reviewing log book entries for a book I’m working on about my flying experiences. I just re-read that post and I do recommend it. It’s short — for me, anyway — and tells an interesting story that gives you some insight into the minds of helicopter owners and pilots.

Burro Creek Bridge
Plenty of room to fly under, no?

Anyway, yesterday I drove north on Route 93, starting my annual migration from my snowbirding stay in Arizona to my late winter/early spring work site in the Sacramento area of California. (Yes, my seven-month “vacation” is nearly over.) I gave myself about 10 days to make the trip and planned stops along the Colorado River near the Hoover Dam, Death Valley, and possibly Lake Tahoe. Or the California Coast. I don’t really know yet. One of the things I like most about my life these days is my unfettered ability to make and change plans on the spur of the moment.

I’d been thinking about the drive for a while, wondering what stops I could make along the way. Burro Creek was a no-brainer. There’s a BLM campground down along the creek about a mile or so off Route 93. I’d considered stopping there for an overnight stay on my way south from Vegas in November but had ultimately chosen a different route that kept me on the Colorado River. The campground isn’t much — in fact, the water is turned off there so the bathrooms are closed up and I’m not even sure if you’re allowed to use the dump station — but it does have ramadas (shade structures) at each campsite, along with picnic tables and a nice desert garden. And plenty of hiking opportunities.

Burro Creek Bridge
A view back toward the campground, looking southwest. That’s Route 93 south of the bridge in the distance.

Burro Creek Campground is about an hour north of Wickenburg, which is where I’d spent the previous two nights. Perfect timing for a break on my estimated three hour drive to Willow Beach on the Colorado River near Hoover Dam. I pulled in, drove down the cracked asphalt road to the campground, and parked in the day use area so the campground host wouldn’t try to hit me up for camping fees.

The Burro Creek Bridge — or should I say bridges? — is clearly visible from the campground. It’s a pair of two-lane truss arch bridges that are about 680 feet long about 390 feet over the floor of Burro Creek’s canyon. The first bridge was built back in 1966 and carried all northbound and southbound traffic. In 2005, as part of route 93’s widening project, they built a second almost identical span right beside it. The new bridge now handles northbound traffic while the old bridge handles southbound traffic. I’m glad they built a matching bridge. It really helps preserve the aesthetics.

Burro Creek Bridge
The two bridges are nearly identical, despite being built 40 years apart.

(A side note here: Route 93 between Wickenburg and I-40 near Kingman had the local nickname “Death Highway” because of the number of deadly accidents — often head-on collisions — that occurred there when it was just one lane in each direction. Widening it was long overdue since it handles nearly all auto and truck traffic between Phoenix and Las Vegas. Parts of it are still one lane in each direction. You can learn more about Route 93 in Arizona on Wikipedia.)

I had done a photo shoot of the new bridge back in 2005 with an aerial photography professional. It was a memorable flight, mostly because he did the shoot with a pair of Hassalblad medium format film cameras. These are extremely costly cameras and the reason he had two of them was so that when he finished shooting a roll of film, he could switch to the other camera instead of fumbling at an open aircraft door to reload film. I think each roll only had 12 shots. I distinctly recall hearing the mechanical sound of the shutter and his manual winding of the film though the intercom system since the microphone was so close to the camera. I orbited the bridges several times. I know he was disappointed with our timing; the second span wasn’t quite done but yet it wasn’t open enough to be dramatic. There was just a narrow gap maybe 50 feet wide in the middle of the roadway. We should have arrived about two weeks before for a more dramatic shot or two weeks afterward for a completed span.

I was thinking a lot about that photo shoot as I walked down to the creek with my Mavic Pro flying camera tucked away in my day pack. The construction company — or Arizona Department of Transportation? — had flown the photographer in to Phoenix from somewhere in the midwest for the shoot. He’d rented a car and drove to Wickenburg. I flew him up there with the doors on, then landed in the construction area to pull off his door and stow it in the back seat. We’d done the flight, circling around and and around. It was midday, but there were still shadows because of the angle of the sun in the deep canyon. I’d landed again to put the door back on and then we’d headed back to Wickenburg. The only reason we hadn’t done the whole flight with the door off was because I could get better speed in transit with the door on and it was at least a 30-minute flight. I’m thinking the whole job was about 1.5 hours of billable flight time, but without consulting my logbook, I can’t be sure. Total cost of those photos? Easily a few thousand dollars.

Burro Creek Bridges
Really. Nearly identical.

I walked as far as I could — at least a half mile — getting almost under the power lines that spanned the canyon just southwest of the bridge. I was hoping to be on the other side of them so I wouldn’t have to worry about them interfering with drone operations, but Burro Creek was running full and fast and I’d gone as far as I could without getting too close to the canyon wall. I spread out my collapsable landing pad in one of the few boulder-free areas, and got to work setting up the Mavic and its controller for flight. I have it down to a science at this point and it only takes me about five minutes from the moment I take it out of the bag to the moment everything is powered up and the Mavic is in GPS mode.

Mavic Operator
I grabbed this image of the video on the Mavic’s return flight. I circled where I’m standing with the landing pad. You can see the campground behind me.

I couldn’t tell how far above the canyon floor the power lines were. I knew they were lower than the bridge, but I also knew that we’d flown under them. They had to be at least 100 feet up. Still, when I launched the Mavic I kept it just 50 feet up until I knew it was on the other side of the wires. (I now estimate they’re at least 150 feet feet from the canyon floor, but likely more than 200.)

I spent the next half hour or so flying around near the bridge. I flew over it once and under it three times. I didn’t want it to distract drivers on the road, so didn’t fly anywhere where the average driver would see it. I had to bump up the maximum altitude for the flight over the bridge, but I figured that was okay because I was still within 400 feet of either the bridge roadway or canyon walls. Certainly nowhere where a manned aircraft should be flying — although I think I’ve already established that it was where a manned aircraft could be flying.

This photo was shot from under the power lines.

I switched batteries after two flights and used up 20% of the second battery before finishing up. Penny had very patiently waited nearby. She doesn’t mind the drone or its bee-like buzzing but stays clear of the landing pad when it’s coming or going.

When I was finished, I powered everything down, replaced the Mavic’s gyro lock and cover, and folded it up. Within a few minutes, I was ready for the return hike with everything stowed away in my day pack again.

I got a bunch of video shots, as well as some still shots. This blog post shows off mostly screen grabs from the video. Launching from the stream bed inside the canyon limited what I could do, keeping in mind that I had to keep the Mavic within sight during the flight (per FAA rules).

I think that if I’d launched from up alongside the roadway, level with the bridge, I could have gotten the same shots that Hassalblad photographer had captured twelve years before — for a lot less money. But there really wasn’t a good place to launch from that wouldn’t distract drivers. And it isn’t as if this was a real mission. It was just more practice.

I wonder what that Hassalblad photographer is doing these days. I seriously doubt he’s still using those cameras to take aerial photos.

Drone Pilots: Beware of Bird Strikes!

Just a quick warning, with photos.

Last week, I did a few photo missions with my Mavic Pro flying camera. For two of the msisions, I launched from an open area at the far east side of the Tyson Wells complex in Quartzsite, just south of Keuhn Road.

I’m in the habit of using the Return-to-Home feature of my Mavic to get it back to its launch point quickly and efficiently. In all honesty, I’m awed by its ability to land exactly on its takeoff spot nearly every single time. I like to watch, with my finger poised over the pause button on the control (just in case), as it comes to the right coordinates far overhead, turns to the direction in which it took off, and descends to the spot.

On one of the three missions I flew from that spot, a small flock of pigeons flew right past the Mavic. I watched in shock and a bit of horror as the five or six birds swooped around my fragile aircraft. I felt relief as the Mavic continued its descent unharmed, but the whole thing repeated itself when another flock — or the same flock? — swooped past. Again, the Mavic was unharmed.

I happened to have the video camera going when this was happening. Here are two screen grabs, one from each flight, that show the closest encounter. The first one was definitely closer.

Near Miss
This reminds me of a scene from The Birds.

Near Miss
The bird is a bit farther off in this one. Can you see it?

Of course, the camera can’t capture action in a direction it isn’t pointing. For all I know they could have come closer behind the camera.

While this is all kind of cool in a weird sort of way, it wouldn’t have been so cool if one of those birds clipped a rotor. The Mavic has four independently powered rotors. If any one of them was destroyed, I’d have to think the whole thing would immediately go out of balance and crash. This is one good reason why we don’t fly drones over crowds of people. Even though the Mavic weighs in at less than 2 pounds, having one crash onto your head from 150 feet would definitely cause some injuries.

Honestly, I’m surprised this hasn’t happened yet. A matter of time?
