Geologic setting

Geologic description An unpublished National Park Service map and accompanying database identify this prospect. The database indicates that a lode mining claim for copper in basalt was located in this area between 1975 and 1981 by the Sheep Creek Mining Company. The bedrock in the surrounding area is part of the Jurassic or Cretaceous, Nutzotin Mountains sequence of marine clastic, sedimentary rocks (Richter, 1976). No other basalt-hosted copper occurrences is known in this sequence.
