The divide between Lewis and Clark and Cascade counties runs vertically through this landscape, marking a transition in the central Montana plains. The drainage network is the defining structural element of the area, centered on the various branches of Simms Creek. To the north, Loomis Coulee and Anderson Coulee carve through the terrain, while the Crown Butte Canal provides a managed water route to the east. This 2017 survey reveals a classic rural township-and-range grid, where the movement of water and the paths of roads like Simms Crk Rd and Long Butte Rd dictated the patterns of land use. The presence of the canal alongside the natural forks of N Fork Simms Cr and S Fork Simms Cr highlights the region's reliance on both natural and engineered water systems.
