Death Valley National Park, California. Typical stand of burroweed near the road along Furnace Creek Wash, above Corkscrew Canyon. This shrub grows on the high parts of the gravel fans above the main stands of creosote bush. Burroweed grows in washes between bare surfaces on the fans with desert pavement. Commonly, desert holly grows along the sides of the washes, and burroweed on the bottom. Photo by J.R. Stacy, circa 1960. Figure 18, U.S. Geological Survey Professional paper 509. Sketch of photo.

Death Valley National Park, California. The last big earthquake in Death Valley accompanied the faulting that produced this escarpment near the road just south of the Furnace Creek fan. The fault movement occurred about 2,000 years ago, and since that time the fault escarpment has been buried where it crossed the mouths of the canyons issuing from the Tertiary formations at the north end of the Black Mountains. Photo by J.R. Stacy, circa 1960. Figure 72, U.S. Geological Survey Professional paper 494-A. Sketch of photo.
