Comments on the geologic information

  • Geologic Description = The bedrock is the Cretaceous Valdez Group metasediments (MacKevett and Holloway, 1977). Small quantities of gold have been recovered from the upper part of glacial-fluvial gravel benches along the banks of the Kenai River (Martin and others, 1915). Gold from the Kenai River valley is very fine, light, and flaky, and has a value of about $17.58 per ounce (with gold at $20.67 per ounce)(Martin and others, 1915, p.199).
  • Age = Quaternary.

Comments on the workings information
