|Location and accuracy||Beaver Creek is not labeled on the U.S. Geological Survey topographic map; it is probably the creek that flows through the middle of sections 22 and 27, T. 22 S., R. 14 E. , Kateel River Meridian (Cobb, 1976 [OFR 76-567]. Beaver Creek is a north-northeast flowing, headwater tributary of Graham Creek. The coordinates are for the approximate midpoint of the creek. The location is accurate within 2 miles.|
The rocks in the vicinity of Beaver Creek are chert, argillite, and volcaniclastic strata (Chapman and others, 1987). Prospecting or mining along Beaver Creek was first reported in 1926 (Holzheimer, 1926 [MR 64-1]. Prospecting and development work are also reported in 1940 (Smith, 1942). At least 1,640 ounces of gold and 163 ounces of silver were recovered from Beaver Creek between 1910 and 1950 (Bundtzen and others, 1987). The average fineness of the gold at Beaver Creek is 910 (Metz and Hawkins, 1981).Also see OP003.
