|Location and accuracy||Willow Creek is a 5-mile-long, headwater tributary to Robert Creek, approximately 7 miles north-northeast of the north end of Twin Lakes. There is an early reference to placer prospecting on Willow Creek but no information on its location along the creek. Arbitrarily, this site is located about 2 miles upstream from the mouth of the creek, near the northeast corner of section 30, T. 33 N., R. 6 W.|
Geologic descriptionReed (1938) reported that very good placer gold prospects were found in Willow Creek in the early 1900s. A small amount of gold was probably produced during the prospecting. Kurtak and others (2002) note that 28 placer claims were staked and kept current on Willow Creek from 1982 to 1986. They saw no evidence, however, of past or ongoing mining along the creek. Some of their panned concentrates from the creek contained small amounts of gold.
