Comments on the geologic information

  • Geologic Description = Placer scheelite was reported to occur near the west foot of the Horn Mountains (Cady and others, 1955). The Horn Mountains form a volcano-plutonic complex similar to Chicken Mountain in the Iditarod quadrangle. In light of known geology, the report of scheelite is considered valid by M.L. Miller.
  • Age = Tertiary/Quaternary
