Not much ground covered today! I took my time and enjoyed the surreal landscape. Tiny footprints are visible everywhere in the sand. On the left side of the road is an area off-limits to vehicles where one can see the slightly-less-disturbed dunes. Rippling sand patches cover the road in places.
The stretch of highway within the dunes is relatively short - maybe six miles. I stopped at a viewpoint for awhile, and watched all manner of ATVs and dune buggies crest the dunes. Soon, the flowing sands became packed gravel, trash, and windblown shrugs. I camped down by an arroyo, half a mile from a border patrol station.
