Geologic setting

Geologic description

At this site calcarenite and siltstone, probably belonging to the Lower Cretaceous Herendeen Formation, are cut by a diorite dike (Wilson and others, 1995). Two samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in copper and zinc (Wilson and others, 1988).
