|Location and accuracy||This placer gold occurrence is on a south-flowing tributary to lower Wickersham Creek, just above its junction with Butte Creek. The tributary, locally called Tammany Creek, is not named on the topographic map. The area of activity extends about 2 miles downstream from the map site, which is in the SE1/4 of sec. 13, T. 21 S., R. 1 W., of the Fairbanks Meridian. This is location B-4 of Balen (1990: 34-90).|
Geologic descriptionThe drainage basin of Tammany Creek contains Tertiary or Cretaceous granodiorite and Cretaceous or Jurassic turbidites (Wilson and others, 1998). The placer gold was probably derived from auriferous lodes, such as those at HE172 and HE178.
