Location: Glacier Creek is a north-flowing tributary of Big Creek, and is about 3 miles long. The placer ground along Glacier Creek is located approximately at the midpoint of the creek, 3 miles south-southeast of Ruby. The coordinates listed correspond to location 3 of Cobb (1972 [MF405]) and mark the approximate midpoint of the creek, in section 22, T. 9 S., R. 17 E. of the Kateel River meridian. The location is accurate within 1.5 miles.
Geology: The bedrock underlying Glacier Creek is slaty schist; abundant crystalline limestone and dolostone are present at the head of the creek (Eberlein and others, 1977). Gold was found on Glacier Creek as early as 1946 (Mertie, 1936). In 1953, a sluice box concentrate contained 29 percent bismuth (White and Stevens, 1953). Near the head of the creek, muck and gravel are about 70 feet thick. Cassiterite and some gold were recovered from dump piles (Eberlein and others, 1977) of unknown location. The main pay streak is about 1 1/2 to 2 miles downstream from the head of the stream. It is about 10 feet wide and 2 feet thick, and occurs in a bench on the east side of the creek. Chapman rand others (1963) reported estimated gold yield from some workings was 25 to 30 cents per square foot of bedrock (gold at $35 an ounce).
Workings: Glacier Creek was intermittent mined prior to 1977 and may have been mined or explored more recently (Eberlein and others, 1977).
Age: Quaternary.
Production: Estimated gold yield from some of the workings was 25 to 30 cents per square foot (gold at $35 an ounce) (Chapman and others, 1963).
