The Montana Idaho border cuts through this high-altitude landscape where the Clearwater National Forest and Lolo National Forest converge. The terrain is defined by a series of prominent ridges, including Swamp Ridge, Pollock Ridge, and Hanson Ridge, which dictate the flow of numerous drainages like Japanese Creek and Pollock Creek. High-mountain water bodies such as Siamese Lakes, Straight Lake, and Fish Lake are centered in the northern half of the quadrangle.
