2014 Map of White Horse Coulee

About this map

Larb Hills anchor this high plains landscape along the boundary of Phillips and Valley Counties, where the drainage systems of Larb Cr and its many tributaries carve a network of coulees. The map documents a land shaped by erosion and seasonal water, featuring distinctive landforms such as The Sag and White Horse Coulee. The presence of Beartracks Reservoir and numerous ephemeral streams like Spring Cr and Sage Cr indicates the critical importance of water management in this cattle-ranching region. Transportation is defined by remote thoroughfares including Carnahan Trail Rd and Content Rd, which follow the natural contours of the terrain to connect disparate grazing lands. The topography is a complex arrangement of ridges and draws, from Black Coulee in the north to Badland Coulee further south, illustrating the intricate hydrography that defines the eastern Montana breaks.
