The Bitterroot Mountains form the backbone of this high-elevation landscape where the Montana-Idaho state line divides Lolo National Forest from Clearwater National Forest. This modern 2024 survey documents the intricate network of forest roads and snowmobile routes, such as the E Fk-W Fk Butte Snowmo Tr # 7, that connect the region's prominent peaks and drainages. The terrain is defined by deep creek valleys like Cloudburst Creek and West Fork Butte Creek, which fall away from high points including West Fork Butte and Skookum Butte. Localized geography is marked by landmarks such as Sally Ridge and Sally Basin in the north, while the southern reaches feature the high-mountain waters of Granite Lake and Lily Lake. The transition between Missoula County and Idaho County is clearly delineated alongside the remote Lost Park Meadows.
