Fine hand drawn map of a section of the Snake River, tracking also the Stage Road to Ross Fork and illustrating Bonanza Bar.
Bonanza Bar was centered on the mouth of Fall Creek, with Badger Bar, Warm Springs Bar, Sagebrush Bar, Bed Rock Bar and Boyd Claim Bar shown further to the left, near Raft River.
Gold Mining on the Snake River
The earliest recorded mining on the river was by soldiers from Fort Boise who mined near the confluence of the Boise River and the Snake. Rich gold discoveries in the Boise Basin in 1863 led to a rush to the upper Snake River, which resulted in mostly disappointment.
By the 1870s, most of the miners on the river were Chinese. As was generally the case in western placer camps, the Chinese were relegated to the low grade deposits which the Snake generally contained. The best were located on Bonanza Bar west of American Falls. This site, as well as the area from Raft River to Buhl, was extensively worked during the late 1800s and into the 1900s.
