This site is located within Denali National Park and Preserve.
Location: Reed and others (1978, locality 12) locate this occurrence in the northwest quarter of Section 36, T. 22 S., R. 23 W., of the Fairbanks Meridian in an easterly draining tributary to the Swift Fork Kuskokwim River at about 4000 feet within Denali National Park and Preserve. Location is approximate.
Geology: The location of this site is approximate. Reed and others (1978) describe a float sample of quartz semischist that contains unknown secondary hydrous copper carbonate minerals. The sample site lies near a thrust fault that places Devono-Mississippian(?) black shale and calcareous sedimentary rocks (Pzsl), considered to correlate with the Totalanika Schist in the Kantishna Hills to the north, over a lower Paleozoic quartzite, semischist, and metavolcanic rocks (Pzsv) (Reed and Nelson, 1980).
Workings: Reed and others (1978) describe a float sample of quartz semischist that contains unknown secondary hydrous copper carbonate minerals.
