The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This occurrence is low on the east valley wall of the White River. It is at an elevation of about 4,100 feet, 3,600 feet northwest of elevation 6368 (Bend) and about 2,700 feet west-southwest of the center of section 11, T. 2 S., R. 20 E., of the Copper River Meridian. This is locality 154 of MacKevett (1976); the location is accurate to within 1,000 feet.
Geology: This occurrence is associated with altered and weakly mineralized rocks along a 160-foot-wide fault zone near or in the Totshunda fault zone (MacKevett, 1976, 1978). In this area, the Totshunda fault juxtaposes Triassic Nikolai Greenstone to the north against upper Paleozoic volcanic and sedimentary rocks to the south (MacKevett, 1978). A sample of the altered rocks contained 3 parts per million (ppm) silver, 300 ppm arsenic, 200 ppm cobalt, 200 ppm copper, and 200 ppm zinc (MacKevett, 1976).
Workings: Only limited surface sampling.
