Comments on the geologic information

  • Geologic Description = Placer gold mining of about the lower one-half mile of Disappointment Creek started in 1914 and continued intermittently until 1939 (Hoare and Cobb, 1977). The pay streak was as much as 300 feet wide. The gravels were 10 to 12 feet thick upstream and more than 35 feet thick at the mouth. The gravels comprised mostly small and well-rounded pebbles and cobbles as much as 8 inches in diameter. The placer concentrates included hematite, magnetite, and minor platinum (Harrington, 1918). Bedrock near the mouth includes slate and conglomerate. Elsewhere in the drainage, Carboniferous (?) to Cretaceous sedimentary and volcanic rocks are intruded by Mesozoic or Tertiary granitic rocks (Hoare and Coonrad, 1959).
  • Age = Quaternary.

Comments on the workings information

  • Workings / Exploration = Open-cut mining took place intermittently from 1914 to 1939. A shaft sunk 35 feet failed to reach bedrock near the mouth, but it was abandoned because of flooding.
