Historical Overview

In 1849, a notorious horse thief named James 'Yankee Jim' Robinson accidentally discovered a highly lucrative placer gold deposit in Placer County while hiding from law enforcement. To conceal his massive find, Jim constructed a horse corral directly on top of his diggings, but his subsequent displays of large nuggets at nearby mining camps drew intense suspicion. When a mob discovered his horse-stealing operations in 1852, Jim narrowly escaped hanging by fleeing to Southern California, leaving behind his amassed gold fortune. He was eventually captured and executed in San Diego, and his legendary hidden hoard has never been recovered from the ridge.
