Britton (Eagle) Creek flows southeast for 11.5 kilometres before entering the Tulameen River, 10.5 kilometres west-southwest of the town of Tulameen.

The lower part of the creek descends rapidly into the Tulameen River through a narrow V-shaped canyon, 4 kilometres long. The upper part of the creek, and its various tributaries, flow through broader, flaring valleys. The stream contains gravel deposits of limited extent, especially in the lower sections. Above the canyon, the gravels are deeper and more widespread.

Coarse gold and platinum were recovered near the mouth of the creek (Geological Survey of Canada Memoir 26, page 135). These deposits were prospected and mined as early as 1885.
