This placer prospect lies on Doyon, Limited selected or conveyed land. For more information, contact Doyon, Limited. See also Washington Creek (CY035), Nugget Creek (CY023), Dome Creek (CY009), and Surprise Creek (CY031).
Location: Eagle Creek is a northwest-flowing tributary of Washington Creek. It joins Washington Creek about 1 mile downstream of the Dome Creek junction. Eagle Creek is about 5 miles long. The coordinates are for the center of mining activity along Eagle Creek, in section 33, T. 4 N., R. 27 E., of the Fairbanks Meridian, although placer mining and prospecting probably took place along the length of the creek. The location is accurate to within 1 mile. This creek is located within Doyon, Limited selected or conveyed land.
Geology: Placer gold was first found in Eagle Creek in 1907. The creek has been prospected but was never mined (Lyle, 1973). The bedrock in the Eagle Creek drainage is composed of Cretaceous to Tertiary sandstone, conglomerate, and mudstone. The sedimentary rocks are poorly sorted and poorly consolidated, and the conglomerate contains well-rounded clasts (Lyle, 1973; Dover and Miyaoka, 1988).
Workings: Placer gold was first found in Eagle Creek in 1907. The creek has been prospected but never mined (Lyle, 1973).
Age: Tertiary - Quaternary?

Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a).
