1949 Map of Cedar Hill

About this map

Ammon sits at the northeastern corner of this 1949 landscape, where the high plains of the Missouri River Basin meet the complex drainage systems of the Wyoming interior. This territory is defined by a series of significant cattle operations that established the local economy, including the Stephenson Ranch, Cundall Ranch, and Stirrup Ranch. The map captures the area just as aerial photogrammetry was becoming the standard for the Geological Survey, providing a precise look at the seasonal water sources and ranching infrastructure necessary for survival in this environment.
