|Location and accuracy||This prospect is along the west side of lower Nabesna Glacier. It is at an elevation of about 3,500 feet in the SW1/4 of section 7, T. 4 N., R. 14 E. of the Copper River Meridian. This is National Park Service locality WRST-28 (unpublished data) and the coordinates for this prospect were provided by the National Park Service.|
Geologic descriptionAn unpublished National Park Service map and accompanying database identify this locality as a gold and cobalt prospect.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).
