Economic information

Comments on the geologic information

  • Geologic Description = Tiny Gulch cuts through alluvial bench deposits on the south side of Bear Creek (RM032). From 1909 to 1914, placer mining of 2- to 3-foot-thick gravels on the lower part of the creek produced about 250 ounces of gold (Maddren, 1915).
  • Age = Quaternary.
