Table of Contents
This district is in eastern Placer County 25 miles northeast of Forest Hill and about 10 miles south of Cisco. It includes the Sailor Flat, Robertson Flat, Sailor Canyon and New York Canyon areas.
The Canada Hill channel, a branch of the Tertiary American River, is believed to have flowed northeast and east across Sailor Canyon and then southeast to join the southwest-flowing main Tertiary channel near French Meadows. The channel is steep, narrow, and has not been too productive. The gravels are usually angular and poorly washed. Bedrock is slate and quartzitic schist of the Blue Canyon Formation (Carboniferous) and schist of the Sailor Canyon Formation (Lower Jurassic). The gravels are capped by rhyolite and andesite. There are some gold-quartz veins that contain abundant sulfides.
