|Location and accuracy||This occurrence is on the crest of the continental divide in the headwaters of French Creek. It is about 1,000 feet east of elevation 1,223 on the divide. This is locality 34 of Gamble (1988).|
Geologic descriptionQuartz-hematite (?) veins and gossan zones in marble are developed near a small fault (Gamble, 1988). A sample of gossan contained 20 % Fe, 1,100 ppm As, 270 ppm Zn, 80 ppm Sb, and 10 ppm Mo. A sample of the veins contained 1,400 ppm Zn and 250 ppm As. The marble is Lower Paleozoic in age (Till and others, 1986).
