Location: Gold Moon Gulch is a small east tributary to Quartz Creek; it is about 2 miles southeast of Mount Dixon. The mouth of Gold Moon Gulch is 0.9 miles above the confluence of Quartz Creek and Goose Creek, a north tributary to the Casadepaga River. Gold Moon Gulch is not labeled on current USGS topographic maps. This is locality 60 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Gold Moon Gulch flows near the contact between marble and schist. A very uneven bedrock surface is developed on the marble including underground caverns (karst ?) that rob water from the surface. Coarse gold, some with quartz, to 0.8 ounce nuggets has been recovered. The bright, angular character and common attachment to quartz suggested to Smith (1910) that the gold was locally derived. Bedrock in the area is primarily part of a pelitic schist assemblage of possible Cambrian or Precambrian age (Till and others, 1986); some Paleozoic marble is also probably present.
Workings: Small-scale placer operations took place in 1907 or 1908.
Age: Quaternary; the numerous incised terraces along the Casadepaga River indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.
