Comments on the geologic information

  • Geologic Description = At this site, near the American Bay batholith, sandstone, shale, and mudstone of the Eocene to Oligocene Stepovak Formation are cut by basalt or diabase dikes (Wilson and others, 1995). Five rock samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in antimony, arsenic, lead, and zinc (Wilson and others, 1988).
  • Age = Eocene or younger.
