Location: Colorado Creek is about 6 miles west of Eagle; it is a 12-mile-long tributary of Mission Creek. Colorado Creek has also been referred to as Boulder Creek. The location of placer gold mining on Colorado Creek is uncertain; the mine coordinates are arbitrarily placed at the approximate midpoint of the creek, in section 36, T. 1 S., R. 31 E., of the Fairbanks Meridian.
Geology: The rocks in the vicinity of lower Colorado Creek are Paleozoic quartz-mica schist and greenschist and Tertiary to Cretaceous sedimentary rocks; the upper part of Colorado Creek is underlain by Paleozoic greenstone (Foster, 1976). Prospecting occurred on Colorado Creek in 1896, but gold was not found in paying quantities (Spurr,1898). Mining occurred on Colorado Creek in 1902 (Brooks, 1903). Mission Creek (EA033) had placer gold production downstream of Colorado Creek.
