About this map

Lolo National Forest and the Bitterroot National Forest meet at a high-elevation boundary along the border of Missoula and Ravalli Counties. The terrain is defined by a series of prominent summits including Lolo Peak, Sweeney Peak, and Mormon Peak, which separate numerous glacial basins and drainages. This high country is dotted with small alpine water bodies such as Carlton Lake, McClain Lake, and the One Horse Lakes chain, providing a clear picture of the hydrological patterns at the headwaters of the regional creek system.

The northern edge of the map shows the transition from the wilderness toward the valley floor, indicated by the development of Mill Creek Rd and Mormon Peak Rd. While much of the area remains largely undeveloped forest land, the survey tracks numerous named watercourses such as One Horse Cr, Lolo Creek, and Mormon Cr as they descend from the ridges. These landmarks offer a precise look at the geography of the Bitterroot Range in the early 21st century.
