Eureka Dunes ~ Death Valley National Park
Looking south to the Eureka Dunes and Saline Range at sunrise.
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.
