This is a photo gallery which I am putting together in 2018 from a trip back in 2005. I had actually participated in eight Jepson workshops before I ever started doing my photo galleries and so I thought it would be fun to go back and do photo galleries for some of them. This was a trip led by the highly knowledgeable former Death Valley botanist Dana York. The Eureka Dunes sand system is the tallest in California, possibly in North America, rising to almost 700'. The dunes occupy an area about 1 by 3 miles and are located in the Eureka Valley, an enclosed basin located northwest of Death Valley at 3000 foot elevation. The high limestone wall of the Last Chance Mountains looms above the dunes and captures precipitation from passing storms, resulting in a higher level of rainfall than other dunes in the Death Valley area. The dunes in effect thus becomes a vertical reservoir, and there are endemic beetles and plants like Swallenia alexandrae, Astragalus lentiginosus var. micans, and Oenothera californica ssp. eurekensis that live nowhere else in the world. Eureka Dunes is a relatively recent addition to the national park and may be reached by a gravel road off a road running from Big Pine to the Grapevine section of Death Valley. Deckera Canyon is a canyon to the southeast of the dunes that carries the name of the noted California botanist Mary Dedecker. An asterisk next to the common name indicates a non-native species.
