Report: Stonewall Creek LC007410 Dredge piles, an occasional foundation and equipment fragments are the only remnants of the placer operations located in this valley. Pardee and Schrader (1933), Lyden (1948) and Earhart and others (1977) all mention this placer. Lyden (1948) speculated that the gold here was probably derived from quartz veins on Stonewall Mountain. The cobbles in the dredge piles are primarily Precambrian Belt with lesser amounts of intrusive. One patented mining claim adjacent to Stonewall Creek: Giant MS # 1547.
