Beaverhead National Forest dominates this high-elevation landscape in the Pioneer Mountains, where the 2020 survey captures a wilderness of glacial lakes and prominent summits. The terrain is anchored by Mt Tahepia and Mt Alverson in the southwest, with drainage systems like Sappington Cr and Trapper Cr carving through the granite massifs. Alpine basins hold numerous water bodies including Tahepia Lake, Vera Lake, and Rainbow Lake, illustrating the complex hydrology of the range. Small clearings such as Cleve Park and Yanks Pasture break the timberline, while Trapper Creek Rd represents the limited human infrastructure in this backcountry. Notable peaks like Brownes Peak and Sheriff Mtn define the northern skyline, providing a detailed reference for those studying the physical geography of this corner of Beaverhead County.
