Last Chance Canyon - Mojave desert, California

resistant volcanic breccia, tuffaceous sandstones, sedimentary material, ash ejecta. rivers and streams cut through the strata carving a dramatic profile. as you hike along the floor the canyon walls vary from shades of gray, to red, black and buff white. embedded in the walls and buried throughout the washes are fossil remains of three-toed browsing horses, a species of short-legged camel, wolverine, shrew, and saber tooth cats.
