Comments on the geologic information

  • Geologic Description = The lower part of Sunshine Creek crosses benches of Canyon Creek; Sainsbury and others (1972, OFR 511) show placer tailings along the lower 0.5 mile of the creek. There are reports of placer mining here in 1918 and 1934 (Cobb, 1978, OF 78-181). Smith (1910) notes that placers along north tributaries of Canyon Creek derive ther gold from reworking the bench gravels. Bedrock of the area includes a pelitic schist of possible Cambrian or Precambrian age in contact with a lower Paleozoic metasedimentary assemblage to the west in the headwaters of Canyon Creek (Till and others, 1986).
  • 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.
