|Location and accuracy||Healy Creek is a tributary to the Nenana River. The creek has been placer mined for about 8 miles from the mouth of Healy Creek upstream nearly to the junction of Coal Creek. The map site is near the upper end of the workings, in the NE1/4 of sec. 15, T. 12 S., R. 6 W., of the Fairbanks Meridian.|
Geologic descriptionUpper Healy Creek drains an area underlain by Birch Creek Schist cut by Mesozoic to Tertiary granites. Lower Healy Creek drains Eocene to Miocene sandstone, claystone and subbituminous coal (Wilson and others, 1998), unconformably overlain by gold-bearing Miocene gravels. The auriferous gravels are the likely source of placer gold in Healy Creek.
