Location and accuracy Dry Creek (Gulch) is a short north tributary to the Casadepaga River. The mouth of Dry Creek is about 2.5 miles upstream from the mouth of Big Four Creek (SO069). This is locality 66 of Cobb (1972, MF 445; 1978, OF 78-181).

Geologic setting

Geologic description

Dry Creek is incised into a terrace of the Casadepaga River. Mining along the active channel started in 1900 and one person was mining here in 1907 (Smith, 1910). The gold was concentrated on a clay seam and most was fine; a 0.1 ounce nugget was recovered in 1900 (Brooks and others, 1901).

Mineral deposit model Placer Au-PGE (Cox and Singer, 1986; model 39a).
Mineral deposit model number 39a
Age of mineralization 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.

Production and reserves

Workings or exploration Small-scale placer mining took place between 1900 and 1907.
Indication of production Yes; small
