Location: This occurrence is about 2.4 miles east-southeast of the center of the mouth of Ford Terror and about 0.5 mile south of the center of section 19, T. 49 S., R. 77 E.
Geology: A stream-sediment sample at this site contained 1,000 parts per million (ppm) tungsten, 2,000 ppm arsenic, and 30 ppm beryllium (Kimble and others, 1984). A search for the source of this anomaly was unsuccessful other than that a float sample collected nearby contained traces of galena, pyrrhotite, and chalcopyrite. The site is at or near the contact between Cretaceous biotite schist and Tertiary or Cretaceous tonalite (Brew and Grybeck, 1984).
