Wright Creek flows north into the west end of Surprise Lake about 22 kilometres northeast of the community of Atlin. The creek is about 8 kilometres long with its upper reaches flowing west for about 2.5 kilometres. The creek produced approximately 426,049 grams of gold between 1896 and 1945 and was known for producing the coarsest gold in Atlin. It was the seventh largest producer of gold.

The lower section of the creek flows over mafic volcanics of the upper Mississippian to Permian Nakina Formation (Cache Creek Complex) and upper Mississippian to Permian ultramafic rocks (Cache Creek Complex). The ultramafic rocks are often highly talc and serpentine altered. The upper, west-flowing portion of the creek flows over cherts, argillites and minor limestone of the Mississippian to Triassic Kedahda Formation which occurs slightly higher in the Cache Creek Complex. The creek flows just west and south of the southern margin of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite).

The creek was initially mined near its mouth at Surprise Lake by mainly hydraulic with lesser underground mining techniques. The middle and upper portions were developed more recently and with less success due to many large boulders and a lack of water.
