|Location and accuracy||The prospect is at an elevation of about 4,100 feet, about two miles southwest of the summit of Pyramid Peak. The map site is in the SW1/4 of sec. 19, T. 17 S., R. 4 W., of the Fairbanks Meridian. The location is accurate to within 1,500 feet.|
Geologic descriptionThe country rocks in the area of this prospect are Upper Triassic, generally thin-bedded, commonly cross-bedded, carbonaceous shale, argillite, sandstone, and siltstone. The strata are cut by numerous dikes, sills, and plugs of altered diabase and gabbro, and by Upper Cretaceous?-Lower Tertiary granites (Wilson and others, 1998). The prospect consists of pyrite, chalcopyrite, and sphalerite disseminated in the bedded rocks.
