Bare Mountain, a tilted fault block in western Nevada.

Bare Mountain, just south of Beatty Nevada illustrates the defining structural style of Basin and Range extension: a tilted fault block. Its southern part consists of faulted Precambrian and Cambrian sedimentary rock. In this photo, one can see a large normal fault separating brown-colored Precambrian-Cambrian Wood Canyon Formation (below) faulted against lighter-colored Cambrian Carrara and Bonanza King Formations. The Carrara and Bonanza King formations show numerous smaller normal faults within them.
