About this map

The high plains of Garfield County are defined here by a network of drainage systems and ranching infrastructure as they appeared in the mid-1960s. York Reservoir sits at the northern edge of the sheet, feeding into the upper reaches of Langs Fork. The landscape is etched with coulees and seasonal waterways, including Lone Tree Creek and Lynch Coulee, which traverse the undulating terrain.

Evidence of local land use is captured through labels for the Rimrock Ranch and a remote Corral, while the Two Furrow Road cuts across the southern portion of the quadrangle, likely serving as a primary route for moving livestock or equipment. The map also records numerous benchmarks, such as BM 3037, providing specific elevation data across the divides separating Red Horse Creek and Hay Creek. This survey offers a clear look at the spatial organization of Montana rangeland before modern development altered these traditional boundaries.
