Wild Ideas: Rocking, rocking in Death Valley

While I was a huge rock hound at around age six, my interest in geology drifted away as I returned to my first love in nature, wildlife. That said, it’s hard not to be impressed by the geology at Death Valley National Park.

As I wrote in a recent column early in October I camped with my brother, Dana, and his wife, Joyce, at Death Valley, in the Mojave Desert of California. Temperatures were high for that time of year, especially where we camped, which was appropriately named Furnace Creek.

The other impressive feature of the park is its geology. The formations of rock that spell out the geologic history of this area are on full display there, with little vegetation in the way — from jagged peaks to shear cliffs showing layers of uplift and volcanic action over millennia, a golden canyon, pale mounds of borate minerals and salt and sand dunes. There are even boulders that mysteriously move around on the valley floor at what is called the Racetrack (tinyurl.com/wi-racetrack).

Dana met me in Las Vegas, where I had flown in, and during the almost three-hour drive back to the park, he talked about why he and Joyce were surprised to find, over several visits, that the park was one of their favorite spots to camp. The quiet and the rugged geologic features were among their reasons, and I saw some of the latter when we stopped at Dante’s Peak, in the Black Mountains. It offers a spectacular view of the famous Badwater salt flats below and the Panamint Mountains beyond them.

The park was definitely quiet . . . and dry — very, very dry — and hot. While I was there, the park was experiencing unseasonably high temperatures, in the upper 90s most days and topping out at 105 at Furnace Creek the day before I left. According to the park’s website, Death Valley is the “hottest, driest, and lowest national park” in the United States.

The heat and the fact that I’d badly sprained my foot and ankle in a cat-wrangling accident the week before I arrived meant that I couldn’t do even the limited hiking we had planned to do. Instead of hiking, we toured the park using Dana and Joyce’s Eurovan camper and a rented Jeep.

The day after I arrived, my brother took me on the first tour, of Artist Drive, a dirt road that climbs to the top of an alluvial fan at the end of a deep canyon cut into the Black Mountains. An alluvial fan is “a more or less stratified deposit of gravel, sand, silt, clay, or other debris, moved by streams from higher to lower ground,” according to the U.S. Geological Service (geomaps.wr.usgs.gov/parks/deva/ftart1.html). The term “alluvial fan” came up frequently during the trip, perhaps because, in that mostly bare landscape, it was easy to see this geological feature everywhere.

According to USGS, the stretch of the Black Mountains that Artist Drive goes through is called the Artist Drive Formation. It is made up of multicolored rock, most prominently along the section known as Artist’s Palette: “Aprons of pink, green, purple, brown, and black rock debris drape across the mountain front, providing some of the most scenic evidence of one of Death Valley’s most violently explosive volcanic periods.” The varying color came from oxidation and other environmental conditions during the tumultuous years the rock was formed and since, which acted on the exposed rock, making them different colors depending on their chemical makeup.

The tour of Artist Drive was short but offered some lovely views. Another outing in Death Valley, to Titus Canyon, offered more spectacular views of its geology and a few cliff-hanging thrills. Look for more about that in an upcoming column.

Photographing Death Valley

In the middle of the day, with the sun at its zenith, Death Valley’s landscapes looked hot, bleak and two-dimensional. But closer to dawn and dusk, the more-oblique light gave the park’s spectacular mountains, alluvial fans and valleys definition, and deepened their color.

To really do right by Death Valley as a photographer, I would have had to study the light at different times of day, waiting and taking photos of a particular place when the light was most dramatic and best defined the geologic features. However, as this was a vacation and not a photo expedition, I just shot what appealed to me, in the best light available at the time.

Beyond the light, the omnipresent contrails — vapor trails made by the many military and commercial jets that fly over the area — presented one of the biggest photographic challenges. The skies were generally deep blue because of the lack of pollution and moisture in them, but that made the contrails even more obvious. The only option I saw was to try to incorporate them into landscape shots as artistic elements, although they often didn’t cooperate.
