Location: Straight Creek is a 2 1/2-mile-long, east-flowing tributary of Birch Creek, a southeast-flowing tributary of Flint Creek, which subsequently flows northeast into the Sulatna River. The coordinates given correspond to location 6 of Cobb (1972 [MF405]) and mark the center of placer mining ground. The site lies in section 12, T. 12 S., R. 17 E. of the Kateel River meridian. The location is accurate.
Geology: The hill drained by Straight Creek is composed of schist intruded by granitic dikes (White and Stevens, 1953; Eberlein and others, 1977). The contact between granite and schist is located near the mouth of the creek. Gold and cassiterite were mined near the mouth of Straight Creek from a bench deposit of Birch Creek that is cut by Straight Creek (Chapman and others, 1963). A placer mine was first established at Straight Creek in 1916 (Smith, 1917 [BMB153]). Straight Creek was mined until 1920, although more recent prospecting may have occurred along the creek (Eberlein and others, 1977).
Workings: Straight Creek was mined from 1916 to 1920 (Eberlein and others, 1977).
