Comments on the geologic information

  • Geologic Description = Only information is that placer claims were staked along an unnamed stream west of Long Lake (U.S. Bureau of Mines, 1973). The bedrock consists of Tertiary volcanics and Cretaceous to Tertiary medium-grained granite (Nelson and others, 1983; unit Tv and unit TKi11). Unit Tv includes rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows. Potassium-argon ages for unit Tv range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
  • Age = Quaternary.
