The surficial geology in its vicinity consists of Wisconsinan Till, alluvium, bedrock, wetlands, and lakes. The creek is a Coldwater Fishery and a Migratory Fishery. It has one named tributary, which is known as Willow Brook.
Utley Brook begins in Lenox Township, Susquehanna County. It flows south for several tenths of a mile and passes through a wetland before turning southeast. After a few tenths of a mile, the stream turns south for several tenths of a mile before turning south-southwest and passing through another wetland. It then turns south for several tenths of a mile and enters Nicholson Township, Wyoming County. Here, it turns south-southwest for several tenths of a mile, receiving Willow Brook, its only named tributary, from the right. It then crosses Pennsylvania Route 92 and reaches its confluence with Tunkhannock Creek.
