Mojave Desert Ruins...Bonanza Gulch.

The hills surrounding Bonanza Gulch are pock-marked with old mines, some of which, according to local lore, contain the remains of Chinese miners.  These miners were trapped during the late nineteenth century, when white prospectors deliberately caused cave-ins in order to keep the Chinese from competing with them.  Supposedly, the remains of some Chinese were found, when a few of the old mines were excavated during the 1980's.

The building shown in the photograph is the old Bonanza Gulch post office, which served the area through the early 1930's.
