In the spring of 1848, a group of French gold miners arrived and camped in what would later be known as the Auburn Ravine. This group was on its way to the gold fields in Coloma, California, and it included Francois Gendron, Philibert Courteau, and Claude Chana. The young Chana discovered gold on May 16, 1848. After finding the gold deposits in the soil, the trio decided to stay for more prospecting and mining.
