About this map

The Continental Divide serves as the primary geographic and administrative axis for this 1995 revision, separating Flathead and Lewis and Clark Counties. This high-altitude landscape is defined by the intersection of the Bob Marshall Wilderness and the Sun River Game Preserve, showcasing a wilderness managed for conservation and recreation. The mapping of the Continental Divide Trail and the Scenic Trail indicates the importance of backcountry navigation in this roadless area.

Water systems flow in opposing directions from the peaks, with the Spotted Bear River and Three Sisters Creek dominating the western slopes, while Lick Creek and Red Shale Creek drain the eastern side of the divide. Notable landmarks like Hahn Peak and the namesake Three Sisters provide vertical relief, while isolated water bodies such as Sock Lake and Hart Lake are nestled in the high basins. The survey reflects a period of modern wilderness management where traditional federal forest boundaries meet designated wild lands.
