Comments on the geologic information

  • Geologic Description = Placer claims were staked in 1915 after gold was discovered near the mouth of [Little] Eldorado Creek. The creek follows the probable faulted contact between Paleozoic slate and limestone and Mesozoic andesitic volcanics. (Also see Dime Creek, ARDF number CA002).
  • Age = Quaternary.
