2017 Map of Lake Marshall

About this map

Flathead National Forest and Lolo National Forest converge in this high-elevation region of Missoula County, where the headwaters of the Swan River and the W Fork Clearwater River drain opposing sides of the continental divide. The landscape is dominated by steep timbered ridges and alpine summits such as Sunset Peak and Mount Henry, reflecting a wilderness defined by its complex drainage network. A network of forest roads, including Colt Lake Rd and Marshall Lake Rd, provides the primary access points for this backcountry. Lake Marshall sits as a primary hydrological feature near the center of the sheet, feeding into Marshall Cr. The map preserves the 2017 boundaries and land management divisions between these two major national forests, documenting the protected status of the peaks and river forks that define the northern Rockies.
