Location: This placer gold occurrence is on Winter Creek, a tributary to California Creek northeast of Jumbo Dome. Placer activity has occurred upstream from the mouth of Winter Creek, to the map site, which is in the NE1/4 of sec. 2, T. 11 S., R. 6 W., of the Fairbanks Meridian.
Geology: The drainage area of Winter Creek includes a sequence of Eocene to Miocene, poorly consolidated, pebbly sandstone, claystone and subituminous coal, that is overlapped unconformably by Nenana Gravel (Wilson and others, 1998). Most of Winter Creek flows over inliers of Keevy Peak Formation, cut by Pliocene hornblende dacite. The probable source of the placer gold in Winter Creek are Tertiary paleoplacers in the Nenana Gravel.
