2017 Map of Ayer Spring

About this map

Ayer Spring sits near the intersection of several county lines in this sparsely populated stretch of the eastern Montana prairie. The map documents a landscape defined by its drainage systems, most notably Pennel Cr and its tributaries like Dry-Fork Cr, which carve subtle relief into the terrain. Situated at the juncture where Fallon, Prairie, and Custer counties meet, the area represents a classic high-plains ranching environment. Transportation is limited to a few arterial routes such as Westmore Rd and the crossing of Riley Trl. These primitive roads and seasonal water sources reflect the remote character of this region during the early twenty-first century, providing a clear record of the rural infrastructure and land divisions in a part of the state where few formal settlements exist.
