| Relative position | This occurrence is at an elevation of about 4,800 feet on the south side of a glacier that occupies the central headwater tributary of the South Fork Kuskokwim River. The map site is in the SE1/4 section 32, T 17 N, R 23 W, of the Seward Meridian. This is locality 8 of Cobb (1972 [MF 412]; 1976 [OF 76-485]) and locality 24 of Gamble and others (1989). The location is probably accurate to within a quarter of a mile. |
