About this map

The Ninemile Divide serves as the dominant spine of this high-country landscape, tracing the border between Missoula and Mineral counties. Located within the Lolo National Forest, the terrain is defined by a dense network of drainages flowing from the peaks, including Ninemile Creek, Eustache Creek, and St Louis Creek. Evidence of mountain activity is concentrated around Ninemile and the nearby Sparks location.

Prominent summits such as Horsehead Peak and Lookout Mountain anchor the southeastern portion of the map. The intricate topographic detail captures the steep canyons of Deep Gulch and Eddy Creek, illustrating the natural barriers that shaped local transport and forestry. A series of unnamed trails provide the only interior access through this remote forest land, connecting the various forks and gulches of the divide.
