Comments on the geologic information

  • Geologic Description = Berryhill (1963) collected five samples of the modern beach along the Bering Sea side of North Spit (Goodnews Bay). Chromite was present in pan concentrates from all of the samples and it was a major constituent in three of them; magnetite was present in about equal amounts to chromite. The iron content of the samples ranged from 1.3 to 6.1 pounds per cubic yard. There was a trace of gold in the three samples that had higher chromite concentrations.
  • Age = Holocene.
