This is a small placer-mining district in the vicinity of the town of Wheatland on the lower Bear River in western Placer and southern Yuba Counties. During the gold rush placer gold was recovered from the creeks and streams. During the 1930s gold was recovered from the gossan by cyanidation at the Dairy Farm copper mine a few miles to the east and by drag line dredging in some of the ravines.
