About this map

Split Rock Junction serves as a focal point in this landscape where the Sun River winds through the borderlands of Teton and Lewis and Clark Counties. The area is defined by an extensive network of irrigation infrastructure essential to Montana ranching and agriculture, including the Sun River-Slope Canal, the Floweree Canal, and the Kirkaldie Canal. These waterways feed into and draw from significant catchment areas like the Willow Cr Reservoir.

Elevated terrain features such as Carey Butte and Sandy Butte overlook the broad, level expanse of the Kirkaldie Flats. The map reveals a transition from the riparian corridors of the N Fork Willow Cr to the more arid coulees, such as Clemons Coulee and Murphy Coulee. Rural access is maintained through a grid of named roads like Sun Canyon Rd and Warden Rd, which connect remote homesteads to the primary junction.
