Geographic coordinates: -144.62889, 64.1636 (WGS84)
Relative position Michigan Creek drains into the South Fork of the Goodpaster River, approximately 32 miles north-northeast of Big Delta. The creek is approximately 8 miles long and has several small tributaries. The Alaska Division of Mining Kardex file system reports placer mining on Michigan Creek, but it is unclear where mining activity took place. The approximate midpoint of the creek is in SW1/4NW1/4 section 4, T. 9 S., R. 16 E., of the Fairbanks Meridian. A winter trail from the South Fork of the Goodpaster River provides access to the Creek. It is locality 18 of Cobb and Eberlein (1980), who summarized relevant references under the name 'Michigan Creek'.

Comments on the geologic information

  • Geologic Description = The area is characterized by rounded hills and flat-topped ridges (Thomas, 1970). According to Weber and others (1978) the bedrock in the area is composed of gneiss, quartzite, augen gneiss, and some amphibole schist. The gravels on Michigan Creek are 12 to 25 feet thick and contain coarse gold (Brooks, 1916). Eberlein and others (1977) reported that a 1/2 ounce nugget was found on Michigan Creek. Stream-sediment and rock-chip samples collected from unknown locations in the creek drainage contain up to 10 ppb Au (North Star Exploration Inc., unpublished data, 1998).? the first discovery of placer gold in the Goodpaster region was on Michigan Creek in 1915 (Thomas, 1970). However, deposits were low grade, and mining activities soon ended. Before World War I, reports of placer mining deposits in the region were vague (Cobb, 1973; B 1374). Therefore, it is unclear where mining activities on Michigan Creek took place. Cobb (1973; B 1374) reports insignificant placer gold production from the Goodpaster region. It is unclear how much gold was produced from Michigan Creek.
