Location: Fourth of July Creek is a 2-mile-long, northwest-flowing tributary of Long Creek. The placer ground of Fourth of July Creek is found near its mouth, along a bench east of Long Creek as marked by location 21 of Eberlein and others (1977). The coordinates above mark a point in section 4, T. 13 S., R. 17 E. of the Kateel River meridian. The location is accurate within 1/2 mile.
Geology: Fourth of July Creek is underlain by phyllite and quartzite of the Ruby terrane, although a Tertiary granite body is located 3 miles east of the head of the creek (Puchner and others, 1998). Mining took place along Fourth of July Creek in the bench gravels on the east side of Long Creek. Unlike many creeks in this area, no cassiterite was found with the gold (Eberlein and others, 1977).
Workings: This creek was probably mined prior to 1977 (Eberlein and others, 1977).
