Shorty Harris and Ed Cross struck gold in August, 1904, in the Bullfrog Mountains west of Death Valley. One of the towns that sprang up after the strike was called Rhyolite, named for the area's unique volcanic, rock-and-sand compound.
Rhyolite grew as long as the gold held out, from 1905 through 1910. By 1914, Rhyolite was well on its way to becoming a ghost town, but in its heyday, Rhyolite had 3 train lines, 3 newspapers, 3 swimming pools, 3 hospitals, 2 undertakers, an opera and symphony and 53 saloons. By 1919, Rhyolite was a deserted ghost town. more information can be obtained by clicking the link
