Geologic setting

Geologic description

Data from J.W. Reiter and M.J. Olson indicated (1913) the presence of quartz veins in Late Cretaceous graywackes. The quartz veins, 6 to 30 inches thick, contain stibnite, chalcopyrite, and galena. One 8 to 36 inch thick vein can be traced 200 ft (Johnson, 1914).
