Comments on the geologic information

  • Geologic Description = Smith (1910) noted that considerable prospecting had occurred by 1907 along the active drainage of lower Lightning Creek where it crosses terraces of the Casadepaga River. The terrace gravels here are 5 to 10 feet above the active stream. Bedrock in the area is primarily part of a lower Paleozoic metasedimentary assemblage (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.
