Geology of National Parks, 3D and Photographic Tours
This view is looking south from Overlook Hill toward the Caliente Range. Soda Lake Road passes just east of the fringes of saltbush habitat. Plant-stabilized clay-dust dunes are in the foreground area.
During the summer months when daily temperatures typically range above
100 degrees F, the surface of the playa and other sag ponds along the
San Andreas Fault become encrusted with sodium sulfate (less
than 10 percent is sodium-chloride salt). Salt and sodium sulfate were mined intermittently from the playa between the 1880s and 1940s (Hildinger, 1995).
