|Location and accuracy||Wolf Creek is a 10-mile-long tributary of Mission Creek. One mile of Wolf Creek was mined. The mine coordinates are placed next to the cabin shown on the U. S. Geological Survey topographic map of the Eagle C-1 quadgangle (1956; revised in 1973); the location is accurate within 1/2 mile. Wolf Creek is locality 16 of Burleigh and Lear (1994), locality 65 of Eberlein and others (1977), and locality 34 and 36 of Cobb (1972 [MF-393]).|
The rocks in the vicinity of Wolf Creek are Paleozoic schist, greenschist, and greenstone, Paleozoic or Mesozoic serpentinite, and Cretaceous to Pliocene nonmarine detrital rocks (Foster, 1976). Quaternary terrace gravel deposits are extensive near the mouth of the creek. There has been placer gold production downstream on Mission Creek (EA033).Placer gold on Wolf Creek was probably discovered in the early 1900s. Pay gravel was found on Wolf Creek, and it was mined for about 1 mile (Powers, 1935). An automatic dam was constructed on Wolf Creek in 1911 to facilitate placer mining (Porter, 1912). Mining also occurred in 1939 on Wolf Creek (Smith, 1941 [B 926-A]). Tertiary sedimentary rocks along Wolf Creek have been interpreted to be the source of the placer gold (Mertie, 1969). Heavy-mineral concentrates from Wolf Creek contain ilmenite, iron oxides, chromite, zircon, garnet, anatase, and trace rutile, tourmaline, and monazite (Wedow, 1954; Cobb, 1973 [B 1374]).
