Geology: Mertie (1918) reports that placer mining took place along this creek in 1916. Moonlight Creek flows close to the contact of pelitic schist of possible Cambrian or Precambrian age to the east with a lower Paleozoic metasedimentary assemblage, that includes marble in this drainage, to the west (Till and others, 1986).
Workings: Some small-scale mining is reported to have taken place in 1916 along this creek.
Age: Quaternary; the numerous incised terraces along the Casadepaga River and its major tributaries 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.
Commodities (Major) - Au
Development Status: Yes; small
