The terrain is rugged, with steep slopes, and finger ridges dissected by small intermittent or permanent drainages. Streams in the northern portion of this area drain into the Sauk River, while the southern portion drains into the Skykomish River. Main features of this area include Skykomish Peak, Cady Creek Ridge and Cady Creek, as well as the Beckler River's tributary the Rapid River, the true source of the South Fork Skykomish River.
