Location and accuracy | This prospect is about one-third mile northwest of the north peak of Marshall Mountain. It is at an elevation of about 4,200 feet near the center of the SW1/4 section 14, T. 2 S., R. 4 W., of the Copper River Meridian. This prospect is probably located to within one-quarter mile. It is locality 82 of Winkler and others (1981 [OFR 80-892-B]). |
Geologic descriptionWinkler and others (1981 [OFR 80-892-B]) reported that sheared pillow basalt and massive greenstone contains pyrite, pyrrhotite, and chalcopyrite. Old cabins are present at this prospect, below it at timberline, and nearby on Klutina Lake. The metavolcanic rocks are part of the McHugh Complex melange (Winkler and others, 1981 [OFR 80-892-A]). | |
