One of the most visually spectacular destinations of all desert landscapes in North America has to be the Eureka Dunes of Death Valley National Park. At the end of the Pleistocene an ancient lake that filled the valley floor gradually dried up; as the winds blew newly exposed sand the dunes formed — into one of the highest in North America. The highest dune in the complex rises to 650 feet above the valley floor from which the surroundings are a terrific spectacle to witness. Another fascinating feature of the dunes is their propensity to sing or boom when the sand is pushed from a steep slip face. The sound reverberates from inside the dune as a deep bass note — which is sure to amaze.
The valley not only offers visual beauty but endemic biota as well — currently 3 endemic plants and 5 endemic beetles have been identified on the dunes themselves. The Eureka Valley dune grass (Oenothera californica ssp. eurekensis) was the most spectacular to find on our winter trip. I had never seen a grass that looks like this — quite primordial indeed. The other two endemic plants on the dunes are shining milk vetch (Astragulus lentiginosus var. micans) and Eureka Dune evening-primrose (Oenothera californica spp. eurekensis). Though we saw the astragulus, both are best viewed in early spring when in bloom.
The legendary plant explorers of the Eureka Valley are Mary and Paul Dedecker. As self taught botanists they often explored the Mojave looking for plants. One a fateful day in the summer of 1975 the two ventured into the Eureka Valley and eventually into a canyon on the south side of the valley. It was a hot July day when Mary found a shrub in bloom — bright yellow when all other plants were browning in the summer heat. It turned out the this was a new species and a new genus that favors a rare limestone outcrop in the canyon. She aptly named the plant July gold (Dedeckera eurekensis). The canyon itself was later named Dedeckera Canyon and can be traveled (with 4-wheel drive and experience) all the way to Saline Valley.

Very nice photos, hope to visit the area sometime for an Ansel Adams experience, that is photographing the dunes and surrounding area with a large format camera and b/w film.

Fantastic pics Mike. I took the road between Eureka and Saline Valleys as well, back in about 1997…brutal. Glad I had a rented car. Did you see the Marble Bath, noted on the USGS quad? Not what you expect. We need to share our desert trip photos.
Dave- I have done that road twice and missed the Marble Bath each time–guess it was a bit stressful from Saline to the saddle and I was distracted when we passed that spot. -Michael
