Most of the gold occurs within 80 feet of bedrock and consists of particles 1 -2 mm in diameter and 0.1 - 0.2 mm thick or smaller. A USGS study of the San Juan Ridge deposits conducted in the 1960s identified values as high as $6.35 per cubic yard ($35.00 gold), but concluded that rarely do the lower gavels exceed $1.00 per yard ($35.00 gold).
