| Relative position | This occurrence is in Glacier Bay National Park and Preserve at an elevation of about 5,000 feet near the top of the steep west face of a ridge west of Rendu Glacier. It is in the SE1/4, section 6, T. 33 S., R. 52 E. of the Copper River Meridian. It corresponds to sample sites 65048 to 65050 on Figure C-44 in Brew and others (1978). Location 3 of Cobb (1972; MF-424), which refers to the 'Rendu Glacier' deposit, is probably the same occurrence but is shown about 0.5 miles farther to the west and is considered to be a less accurate location. Still (1991 [BOM, v. 2, sec A) refers to this as the 'Massive Chalcopyrite Deposit.'? The deposit is extremely inaccessible. It can only be reached from a helicopter landing site on the ridge by a 200 foot rappel down a vertical to overhanging cliff that continues down for another 3,000 feet. |
