2020 Map of Split Rock Junction

About this map

The Sun River winds through the eastern portion of this Montana landscape, shaping a terrain defined by complex water management and high-plains topography. Centered on the Willow Creek Reservoir, the map illustrates a network of essential irrigation infrastructure, including the Sun River Slope Canal, Floweree Canal, and Kirkaldie Canal. These waterworks supported the agricultural vitality of the region near Split Rock Junction, where the local road system branches out to service scattered ranchlands. To the south, the terrain rises toward distinct landmarks such as Carey Butte and Sandy Butte, while the lowlands features the Kirkaldie Flats and the drainage of Willow Creek. This area, situated along the border of Lewis and Clark County and Teton County, reflects the modern engineering required to sustain ranching and farming in the shadow of the Rocky Mountain Front.
