Location: This occurrence is at an elevation of about 2,600 feet, about 2 miles southeast of the Walker Fork Campground shown on the U.S. Geological Survey 1:63,360-scale topographic map of the Eagle A-2 quadrangle (1956; revised in 1971). The occurrence is in section 6, T. 26 N., R. 20 E., of the Copper River Meridian. The location is accurate.
Geology: The rocks in the vicinity of this occurrence are Paleozoic amphibolite-facies paragneiss, quartzite, and schist that are cut by northeast-trending high-angle faults (Werdon and others, 2001). The quartzite is locally dark gray (biotite or carbon-bearing?), and it is interlayered with quartz-rich biotite gneiss. Samples of an unusual, light-sea-green quartzite contain 1,170 ppm lead and 51 ppm molybdenum (Werdon and others, 2000).
Age: Paleozoic or younger.
