About this map

Bitterroot Irrigation District Canal winds through the lower elevations of this Ravalli County landscape, illustrating the critical role of water management in Montana's agricultural development. The terrain is defined by a series of drainages, including Threemile Creek, Ambrose Creek, and Grayhorse Creek, which flow westward from the high timber of the Bitterroot National Forest. Human presence is anchored by the Lone Rock Sch and a local Cem, alongside scattered extraction sites like a Gravel Pit and several Prospect locations.

Conservation and land use boundaries are clearly delineated, with a significant portion of the eastern territory dedicated to the Threemile Wildlife Management Area. Notable topographic landmarks such as Reed Butte and the Grayhorse formation overlook the complex network of creeks and gulches, including Dry Gulch and Sheep Creek. This map captures the intersection of public forest lands, state-managed wildlife habitats, and the private ranching and farming interests supported by the extensive canal system.
