Feather Creek flows east into the upper reaches of the O'Donnel River sometimes referred to as Dixie Creek. The creek confluence with Dixie Creek is about 30 kilometres southeast of the community of Atlin and has received all of the placer work. A 16-metre shaft was sunk to bedrock and 61 metres of drifting was done from the shaft from 1914 to 1921 but only 156 grams of gold were recovered. An additional 187 grams of gold were recovered in 1937 (Bulletin 28). Recent activity involving a small surface operation using a cat and excavator has been conducted in the same area of the creek in the early 1980s.

The creek flows over chert, argillite, and limestone of the Mississippian to Triassic Kedahda Formation of the Cache Creek Complex. The creek is in a low relief area and there is not a great deal of outcrop.

The best channel gravels are found overlying bedrock. This creek is referred to as Slate Creek on some older maps, in particular Map 1082A of Geological Survey of Canada Memoir 307. On this map, the creek immediately north is incorrectly referred to as Feather Creek.
