Comments on the geologic information

  • Geologic Description = The country rocks at this site are altered sandstone and volcanic rocks cut by andesite dikes and sills (Wilson and others, 1988). The volcanic rocks are mapped as Miocene (Wilson and others, 1995). Five samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in arsenic, barium, copper, lead, tin, and zinc (Wilson and others, 1988).
  • Age = Miocene or younger.
