Location: Quartz Creek is a north tributary to Goose Creek and Goose Creek is a north tributary to the Casadepaga River. The mouth of Quartz Creek is 1 mile above the confluence of Goose Creek and Casadepaga River. This is locality 59 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: By 1907, placer mining had taken place on Quartz Creek just above its mouth for several years (Smith, 1910). The creek is locally incised into older gravels. The gravels that were worked were 3 to 10 feet thick and the gold was recovered from the upper 2 feet of schist bedrock. The gold was coarse, some with attached quartz, and associated with garnet and magnetite. Bedrock in the area is primarily part of a pelitic schist assemblage of possible Cambrian or Precambrian age (Till and others, 1986).
Workings: Small-scale placer workingstook place along the lower part of the creek for several years up to 1907.
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.
