Predator Tracks Picture of the Week

We need to drive an hour to show you a different part of the Algodones Dunes. I hope you had breakfast because we’re not stopping. There are only two roads that cross the dunes, Interstate 8—east of Yuma and California State Highway 78. We’ll hop onto I-8 and head west to Holtville, then north to Brawley.

Most of this drive is flat and dull except for the towering green John Deere tractors that take up three lanes of the two-lane road. The farmers drive them on public roads to remind you that if you eat steak and salad in winter, this is where they were likely grown—either here in the Imperial Valley or Yuma.

Once we get to Brawley (there’s a bypass, so thankfully, we don’t have to go into town), we’ll turn west onto S.R. 78—the road to Blyth (boy, it keeps getting worse, doesn’t it). It isn’t far out of town that you see a cloud bank on the horizon—or at least that’s what it appears to be. The sand reflects light on a bright day, and the detail gets lost. The shapes and color begin to resolve in another mile, and the windshield fills with an overwhelming sea of golden sand.

We have arrived. This area of the dunes is the home base for So Cal dune-buggy enthusiasts. As soon as the highway starts up the sand, you’ll see Gecko Road on the right. It’s a paved street loaded with vendors, campers, and rangers. This road is a fee area, so we may have to buy a permit if the rangers come to work today. There are several designated camping areas along the road, and they’re full of R.V.s and trailers—even in the middle of the week. Judging from the size and luxury of these rigs, they’ve come from the L.A. Basin—and they’re richer than anyone from Arizona. There must be a thrill racing up and down dunes; otherwise, what’s the point? I wouldn’t try it in Archie, but with Bluto, I might. It could be fun.

It can also be dangerous. Some creatures live in the sand that nobody’s seen—their tracks are the only evidence that they’re real. They’re called sandworms, and they feed on unsuspecting victims as they try to cross. It’s true; they were in the ’90s movie Tremors, and you can see for yourself in this week’s picture called Predator Tracks. In it, you see footprints from a herd of bikini-clad tawny blond valley girls, moving north across the sand while staring at their phones. They were defenseless because they ignored their parent’s warning to take a chainsaw.

As they incessantly chattered about their Instagram likes, they overlooked the sandworm lurking behind a distant mound. Like dolphins feeding on a school of mackerel, the sandworm blindsided the girls. From their midst, it snatched Cassie in its massive jaws and drug her under as she complained about losing all her bars. None of the others noticed. They continued to the snack truck making snide remarks about how Cassie had just ghosted them. The only record of this tragedy is the tracks in the sand in my photo. Within a couple of days, even those will blow away.

Dune Moon Picture of the Week

When Queen Anne and I make our quarterly medical run-to-the-border, the drive is usually three-hours each way. Most of the time, we leave at dawn, see our dentist, buy prescriptions, and then come home. For me, those are long days behind the wheel; for Anne, not so much. She’s usually asleep in the passenger seat until her snoring wakes her up.

Occasionally when we have lab work done, or the customs line is three-hours long because the snow-birds have arrived, we’ll get a room in the elegant east-side Motel 6 and dine at the swanky four-star Denney’s. Our December visit was one of those occasions. Since I needed a topic for January’s posts anyway, we spent an extra night and took a circuitous route home—we’d go up to Blyth to work the Algodones Sand Dunes for this month’s project.

The great swath of sand starts about three miles south of the border outside of Los Algodones, Baja. It continues 45 miles northwest into the Coachella Valley (California’s Imperial Valley). They’re the most extensive contiguous dune system in the U.S. The dunes are also called the Imperial Dunes, Glamis Dunes, and Gordon’s Well. The name varies with location and the leisure activity you’re doing. Still, the entire system is officially named Algodones Dunes (in Spanish, it means cotton plant—the predominant crop grown on both sides of the border along the Colorado River). This week, we’ll start west of Yuma at the Mexican border—at Gordon’s Well.

Imagine it’s 1850, and you’ve traveled by wagon hundreds of miles across the scorching Sonoran Desert, forded a raging Colorado River, and finally crossed into California. You’d think your hardships are behind, but then, you’re greeted with 6 miles of Sahara-like sand to cross. With each step, you sink up to your knees. Even in 1926, when the nation’s first Ocean to Ocean highway was built (U.S. Route 80), the shifting sand was an engineering nightmare. They couldn’t simply scrape the sand away because the prevailing wind constantly covered it up again. Even today, if you’re caught in a windstorm along this section of road, you’ll risk a chance that the sand will blast the paint off your car.

The road builder’s solution for getting across was to build a plank road—movable wood sections on railroad-lie ties that floated on the sand’s top. It turned out to be challenging to maintain, but it drastically cut the crossing time when it was clear. Eventually, the planks were replaced with new and expensive asphalt, and eventually, it became Interstate 8. There is a section of the original plank road at Gordon’s Well on display. When you grow tired of looking at the old wood road, you can walk over to the border wall and lean on it.

As Anne and I drove west on the freeway, we spotted a waning moon setting on the dunes, so we looked for a place to stop. We’ve got stuck in these sands once before, so we were careful not to drive off the blacktop. I didn’t want to pay for another hook to come to yank us out. As you can see, we found a good spot and took this week’s picture called Dune Moon. The name could have been funnier if I had shot it during a particular summer month. Se la vie.

Lava Grass  Picture of the Week

Christmas, along with the rest of the solstice holidays, is almost over. I hope that Santa brought you something better than the lump of coal I got. Queen Anne is on the couch in her bathrobe and tiara with a box of Kleenex. She’ll be useless until Amazon Prime stops showing Christmas movies. Since we won’t be back before then, we’d like to wish you the best New Year in 2022. Things have got to turn around eventually, so let’s give it a go one more time.

Today, I will finish up the year, and our visit to Snow Canyon State Park by talking about the other rock found there—basalt from recent lava flows. If wind, water, and ice sculpt sandstone, the cooled magma is geology’s Etch-a-Sketch reset button. The black rock covers the softer sandstone and forces water to change course. The runoff carves different canyons, like in the park.

As you explore the park’s north side, you’ll see basalt-covered cliffs. They used to be the canyon floor, but 27,000 years ago, the lava forced the drainage west and carved a new floor—now a couple of hundred feet lower. Snow Canyon has a couple of trails that wander through the jagged black rocks; the Lava Tube and the Cinder Cone trails. The latter is interesting because you can hike to the cone’s rim and look into the extinct caldera. However, the track is uphill, and on the east side of State Route 18, so we skipped it.

The Lava Tube Trail is shorter,  level, and leads to two lava tubes—which are places where the hardened surface fractures releasing the still molten magma inside to flow away. The remaining caves are sometimes big enough that you can crawl into and see where the bats and spiders live—I’ll pass. The above photo is the smaller tube, and visitors— braver than I—crawl into it.

I find basalt a challenging subject to photograph. It’s like taking a picture of a black cat in a coal mine. To get any detail, you need to over-expose, which washes out the rich depth. Fortunately, and is the case with this week’s picture that I call Lava Grass, there’s enough green lichen growing on the rock to prevent the shadows from completely blocking up.

I feel lucky to have spotted the tuft of dried grass surviving in the barren rock. I concentrated hard on staying upright as I hiked the trail in the early morning. The jagged basalt is not skin-friendly and will likely draw blood if you fall on it. And—silly me—I left my bicycle helmet at home.

Cup Holders Picture of the Week

I will pause our Snow Canyon State Park tour for a couple of paragraphs so we can run over to the coast. Don’t worry; we won’t have to put up with any of those weird Californians. Where we’re going, they don’t exist yet. We’re not traveling far—maybe a foot or two. However, we are breaking every law in physics to travel back one-hundred-eight million years ago—to the Jurassic era. You can turn around now and take in the Sundance Sea, right here in southern Utah (how old is Robert Redford anyway). Don’t go in the water. Big things in there will eat you like you’re a gummy bear.

Turn back this way and look down the shoreline. Massive dunes—hundreds of feet high—go on for hundreds of miles. Until now, it’s been hot and dry here along the Equator, but the climate is changing. It’s becoming muggier and swamp-like. The oceans are rising, and soon (in geological time), the water will cover the sand and pile more sediment. The pressure on the dunes will bind them into stone—never to be seen again.

Things would have stayed that way, except our stupid captain rammed the North American plate into the Pacific Plate, and there goes the neighborhood. The crash spun us around and raised the Rockies, the Sierra Nevada, and all the other little wrinkles in between. The resulting damage cracked the mantle so badly that volcanoes could form, raising the Colorado Plateau. Then the Californians move in—can it get any worse?

The crash shoved our peaceful little seaside village up a hillside. We no longer live in a basin where sediments collect. Now, our water flows to a place far away. It peels back layers of rock—like an onion when it does. After erosion uncovers parts of the great dunes, we’ll see them again here in St. George, Zion, and north of Escalante. Now they’re as hard as a rock.

You can snap out of it now and return to reality, where we’re standing on the Petrified Dunes Trail. Because it’s all rock, the only clue you have to follow is the path worn smooth from countless boots. It’s easy to leave it, but that’s fine because you won’t damage anything. The rock grips like sandpaper, making it easy to scramble up and down the slopes. As you wander across the uniformly fractured rock, you examine the exceptions.

That’s how I found this week’s picture. The round wells in the picture are places where water is collected and has a chance to freeze. As the ice expanded, it fractured the sandstone and chipped it. These spots get deeper; they’ll hold more water and bore into the stone faster. Eventually, they’ll be so deep that they’ll split the block until it reverts to sand grains. I think the shapes of the cups are fantastic, but I like the rich and varied colors in the stone. When you look closely at this, sandstone has a lot of depth and texture.

Arch and Honeycomb Weathering Picture of the Week

When you were a child and thunder was new to you, did your mother try to console you by explaining that the noise was just God and the angels bowling in heaven? My mom did that. I believed her because she’d never lie to me, and she knew I’d catch her (although I don’t understand why Santa stopped sending me $20 at Christmas when she died). She always told people that I was their peer, although there may be more intelligent children. Well, what her exact words were is, “He sure ain’t the brightest kid in the class.”

Arch and Honeycomb Weathering - inside the cave on the Jenny's Canyon Trail are a natural window and Honeycomb Weathering.

This memory comes to mind because I think I’ve captured the scoreboard that the angels used. It’s visible in this week’s picture—the rows of distorted cribbage holes. If one of the bowlers threw a strike, a lightning bolt would cause a tree to burst into flames. Then they’d advance their marker into the next hole. The one that got their rock in the last spot won. It’s that simple.

I did a lot of online research to prove my thesis, but I found nothing. Instead, the experts call this kind of erosion honeycomb weathering. It’s not clearly understood, but it’s an alchemy of rock, salt, rain, freezing, and expansion. You also have to hold your tongue just right while you’re making it. I saw this type of erosion before in Canyonlands National Park when we visited too long ago, so I assume that it’s shared across Southern Utah’s sandstone formations.

This example of honeycomb weathering is in Utah’s Snow Canyon in a place they call Jenny’s Canyon. It’s at the end of a half-mile (round trip) trail near the park’s south entrance, and it was the shortest and the most rewarding of the side trips that we took. The trail leads to a slot canyon in the sandstone, but not the usual slot. Unlike Antelope Canyon near Page—where running water has cut a course into the sandstone—this is one of those stacked dunes (see last week’s picture) with a gap between the layers. Jenny’s Canyon begins as a typical slot, but dead ends in a short cave. I took my shot from inside the cave.

If you think some weird bacteria are growing on the cave walls, let me explain the color. Like wearing a pair of rose-colored glasses, when the sunlight bounces off the red sandstone, it adds that color to the reflected light, and that’s why the back wall seems to glow orange. Other photographers have successfully captured this phenomenon at Bryce Canyon, but I’ve been unlucky so far. “Damn you, Bryce. I’ll get you one day.”

The second image that I included to illustrate my post is the sky from Jenny’s slot canyon. I’ve seen photos like this, and I wanted one of my own. I think the blue against the glowing orange and dark walls look like torn craft paper glued on one another as a collage. I consider it an abstract because it has no story of its own.
