Comments on the geologic information

  • Geologic Description = At this site volcaniclastic sandstone, siltstone, and conglomerate of the Eocene to Oligocene Stepovak Formation (Wilson and others, 1995) are intruded by numerous basalt? dikes or sills (Wilson and others, 1988). The U.S. Geological Survey collected one sample in the mid-1980's. It was reported to be anomalous in antimony and arsenic (Wilson and others, 1988).
