This creek lies on Doyon, Limited selected or conveyed land. For more information, contact Doyon, Limited. See also: Nugget Creek (CY023), Eagle Creek (CY012), Dome Creek (CY009), and Surprise Creek (CY031).
Location: Washington Creek is a northward-flowing tributary of the Yukon River. The mines' coordinates are arbitrarily placed at the confluence with Nugget Creek (section 8, T. 4 N., R. 27 E., of the Fairbanks Meridian). The exact locations of the placer gold deposits are unknown, but prospecting took place along the entire length of Washington Creek. The location is accurate to within 8 miles. The main portion of this creek is located within Doyon, Limited selected or conveyed land.
Geology: Traces of gold have been found along Washington Creek, but all of the productive placer mines, such as Nugget Creek (CY023), Dome Creek (CY009), Surprise Creek (CY031), and Eagle Creek (CY012) are along tributaries of Washington Creek (Mertie, 1942). The bedrock along middle and lower Washington Creek includes Mesozoic shale, argillite, and quartzite, and Precambrian basalt and red beds. Cretaceous and Tertiary sandstone and conglomerate, as well as Precambrian metamorphic rocks are found near the head of the creek (Dover and Miyaoka, 1988). The traces of gold that might be found in the creek are most likely derived from the conglomerate, but all of the productive mining was on the tributaries (Mertie, 1942).
Workings: Prospecting was done along the creek starting in the early 1900's. Some gold was found in Washington Creek, but all of the productive mining took place on tributaries of Washington Creek.
Age: Quaternary.
