Comments on the geologic information

  • Geologic Description = This site is a gold placer mine about0.5 mile below the headwater forks of Bear Creek. Bedrock in area is early to mid-Paleozoic marble and schist. Prospect was mined intermittently for several years prior to 1930. Mining was done in the portion of the stream underlain by schist (Reed, 1932).
  • Age = Quaternary.

Comments on the production information

  • Production Notes = Production through 1930 reported as 95 ounces (Cobb and others, 1981).

Comments on the workings information

  • Workings / Exploration = Central and Bear valleys were optioned as prospective placer ground in the early 1930's. Preliminary examinations were begun to determine the feasibility of installing hydraulic equipment or a dredge. A line for a ditch about 3 miles long was laid out and surveyed. Prospecting continued through the winter of 1934-35 (Smith, 1936).
