|Location and accuracy||This site is at an elevation of about 600 feet, on the Alaska Peninsula approximately 1.5 miles north of triangulation point Chichagof. It is in the NW1/4 of sec. 8, T. 52 S., R. 71 W., Seward Meridian. It is referred to as PMRGX-13 in Wilson and others (1988, locality 62). The location is accurate to within 1,200 feet.|
Geologic descriptionAt this site, near the American Bay batholith, sandstone, shale, and mudstone of the Eocene to Oligocene Stepovak Formation are cut by basalt or diabase dikes (Wilson and others, 1995). Five rock samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in antimony, arsenic, lead, and zinc (Wilson and others, 1988).
