About this map

The Chesterfield Range dominates this corner of Idaho, with its high-elevation terrain carved by deep drainages and cattle-country outposts. Settled into the eastern foothills near where Grizzly Creek meets Thompson Creek, the Chesterfield Cow Camp serves as a lone marker of human occupation in a landscape otherwise defined by topography and hydrology. To the west, the Sawmill Ridge provides a steep backdrop to the various named springs like Dairy Spring and Millward Spring that feed into the larger river systems.

Water management and grazing patterns are visible through the network of 4wd tracks that navigate around landmarks such as Devils Gate and over Swaps Pass. The northern portion of the map is defined by the winding course of the Blackfoot River, which draws from several tributaries including Negro Creek and Corral Creek. This survey captures the area at a time when traditional ranching infrastructure remained central to the local geography, linked by seasonal trails and high-country passes.
