Comments on the geologic information

  • Geologic Description = Four rock samples of altered basalt collected in this area by the U.S. Geological Survey in the mid-1980s contained anomalous values of arsenic, antimony, copper, and lead (Wilson and others, 1988). The basalt is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995).
  • Age = Eocene or younger.
