2020 Map of Lonetree Coulee

About this map

The Missouri River cuts through the southwestern corner of this landscape, marking the primary topographical boundary in a region defined by high plains and deeply cut drainages. In Chouteau County, the drainage network of Big Sandy Cr and Little Sandy Cr dictates the local geography, with seasonal watercourses carving distinct breaks into the terrain. Transportation in the area relies on a series of historical thoroughfares, most notably the prominent Judith Landing Rd, which provides a vital link across the high country. Local routes such as Mountain View Rd and Sheep Coulee Rd navigate the undulating elevation, reflecting a land usage focused on ranching and large-scale agriculture. The network of trails and unimproved roads, including Lonetree Trl and Kamut Ln, reveals the sparse but intentional infrastructure required to maintain this stretch of the Big Sky state.
