About this map

Mt Douglas and the surrounding high-altitude terrain of the Boulder Plateau dominate this early 1940s survey of south-central Montana. The landscape is defined by the headwaters of the Boulder River and the Stillwater River, where isolated outposts like the Fourmile Guard Station and Box Canyon Guard Station provided early administrative presence in the Gallatin National Forest. Human activity is concentrated in the river valleys at sites like the Clydehurst Ranch and Hells Canyon Ranch, alongside the localized extraction at the Gish Mine near Graham Creek.

A network of glacial lakes, including Emerald Lake, Rainbow Lakes, and Lake Pinchot, highlights the complex hydrology of the high country. The map documents numerous family-named peaks and drainage features, such as Hicks Peak and Wegner Creek, offering a detailed record of the region's topography and early ranching footprint before later 20th-century developments altered the character of these mountain basins.
