Geologic setting

Geologic description

An unpublished National Park Service map and accompanying database identify this locality as a gold and cobalt prospect. Four mining claims were located here between 1972 and 1974 as the Gay 1-4 claims. These claims may have been on or may have included the calcite vein with gold and cobaltite at locality NB041. That vein is in highly altered and limonite-stained Triassic, Nikolai Greenstone(?) near the contact with a Tertiary porphyry intrusion (Richter, 1973).
