A French expedition, said to number three hundred men, worked placers in the San Juan country around 1790 and ran into disaster: attacks, starvation, a brutal winter. The story holds they buried millions in gold on Treasure Mountain before the handful of survivors staggered east. Maps claimed to descend from the expedition still circulate, and the mountain wears the name on the federal quads.
