| Relative position | This site includes a placer occurrence and a lode occurrence. The placer occurrence includes the drainage below McCune Glacier and the southern outwash area of Heney Glacier. The placer covers an area of about 3 square miles. The map site is at about the midpoint of the placer, in the NE1/4 sec. 18, T. 11 S., R. 4 E., of the Copper River Meridian; the location is accurate to within 2000 ft. This site corresponds to loc. P-5 in Jansons and others (1984), which presumably represents both the placer and the lode occurrences. |
