|Location and accuracy||Woods Creek is a small south headwater tributary of Canyon Creek about 2 miles north of Boundary. Woods Creek is commonly referred to as Canyon Creek by local miners. Placer workings extend for the lower 1 mile of Woods Creek,and up an unnamed tributary on the east side of Woods Creek for one-half mile (Yeend, 1996). The mine coordinates are the aproximate midpoint of placer workings on Woods Creek, on the boundary of sections 20 and 21, T. 27 N., R. 22 E., of the Copper River Meridian; the location is accurate. Woods Creek is locality 107 of Burleigh and Lear (1994), locality 66 of Eberlein and others (1977), and locality 74 of Cobb (1972 [MF-393]).|
The rocks in the vicinity of Woods Creek are Paleozoic amphibolite-facies paragneiss, schist, amphibolite, and lesser quartzite and orthogneiss (Szumigala and others, 2002). These units are tightly folded and are cut by a northeast-trending high-angle fault; the creek follows the trace of the fault.Placer gold was mined on Woods Creek in the early 1900s, notably in 1907 (Prindle, 1909). Prindle (1908) included Woods Creek in production statistics for the Canyon Creek drainage, and Canyon Creek and its tributaries produced 447 fine ounces of gold from 1904 to 1907. Placer mining occurred on Woods Creek in 1969 (Asher, 1970) and during the 1990s (Swainbank and others, 1993; Burleigh and Lear, 1994; Yeend, 1996). A small open-cut operation was active on Woods Creek in 2000.
