Location: This site, a scheelite-bearing skarn bed, is located high on the ridge between the headwaters of Big Windy Creek and Puzzle Gulch, NW1/4 SE1/4 sec. 3, T. 3 N., R. 15 E.
Geology: Country rock consists of high-grade pelitic schist with subordinate calcareous schist, marble and augen gneiss. The country rock is intruded by W-bearing granitic rocks. The carbonate rocks are metamorphosed to skarn near the intrusive contacts. Scheelite appears in skarn beds and local quartz monzonite. W values are up to 2000 ppm, with minor Sn, Mo, and Cu (D. Menzie, oral commun., 1986).

Commodities (Major) - W
Development Status: None
Deposit Model: Contact metamorphic tungsten deposit (Cox and Singer, 1986; model 14a)
