The Little Rocky Mountains rise sharply in this 2017 survey of the border between Blaine and Phillips counties. This island range is defined by complex topography, with prominent summits like Old Scraggy Peak, Silver Peak, and Beaver Mtn towering over a network of canyons and gulches. The historic mining legacy of the area is evident in the proximity of Zortman and Landusky, settlements that flourished during the regional gold rush. Numerous drainages such as Ruby Gulch, Alder Gulch, and Mill Gulch radiate from the central peaks, illustrating the erosional patterns that exposed the area's mineral wealth. To the north, the terrain transitions toward the plains near Hays and Lodge Pole, while the Zortman Airport and Zortman Cemetery serve as modern landmarks for the local community.
