About this map

The high plains and rugged draws of the Blackfoot Valley Conservation Area dominate this landscape along the border of Teton and Lewis and Clark Counties. The terrain is defined by a complex irrigation network essential to this semi-arid region, featuring the Sun River, Sun River Slope Canal, and the Floweree Canal which divert water through the coulees. At the heart of the map, the Willow Creek Reservoir serves as a central hydrological feature, fed by the North Fork Willow Creek and smaller tributaries like Willow Creek.

Human presence is sparse, centered on the modest crossroads at Split Rock Junction. Beyond the junction, the map reveals a history of land use through features like Kirkaldie Flats and Clemons Coulee, while local landmarks like Carey Butte and Beals Lake provide fixed points in the shifting topography of the Montana backcountry. The network of local roads, such as Sun Canyon Rd and Warden Rd, traces the contours of the coulees and provides access to the expansive conservation lands.
