Location: Twocent Creek is not named on the Wiseman C-3 topographic map. Based on descriptions by Reed (1938), Twocent Creek, is probably the short, west tributary of Flat Creek whose mouth is about 0.2 mile south of the junction of Deadman and Flat Creeks. Another, less likely, possibility is that Twocent Creek is one of two short, west tributaries to Flat Creek about a mile farther downstream. The coordinates are the most likely locality in the NW1/4 section 8, T. 31 N., R. 17 W., of the Fairbanks Meridian. The location is accurate within 1 mile.
Geology: Reed (1938) reported that miners in the early 1900's could pan small amounts of gold from this creek --two cents worth per pan at the old $20.67 per ounces price of gold. Dillon and others (1986) map the rocks in this area as Devonian Hunt Fork Shale. No other information is available.
Workings: Apparently only prospecting.
Age: Quaternary.
