Eureka Valley is huge. And remote.
Check out the dry lake bed, the Last Chance Range to the east, the Sylvania and Piper regions to the north or giant canyons of the Saline Range to the west. Lots of space to explore.
I've attempted Saline Peak from the dunes, it was a very long day and we never got close.
Eureka Valley from the north. The dunes are in the upper center of the shot.
