2014 Map of Pompeys Pillar

About this map

Pompeys Pillar sits as the focal point of this northern Montana landscape, located just south of the Yellowstone River and north of the expansive Smith Coulee. This 2014 survey documents the intricate water management systems essential to the region, including the Reservoir Line Canal and Lower Canal Rd, which network across the plains to support local agriculture. The terrain is defined by a series of drainages and coulees, such as Barley Coulee, Lost Cabin Coulee, and Fly Creek, which carve through the high ground. Notable infrastructure includes Us-312 and the Anita Reservoir near Anita Dam Rd. The boundary between Yellowstone Co and Big Horn Co is clearly marked in the southern portion of the map, illustrating how historical political lines intersect with the natural topography of the Yellowstone valley and its surrounding creek systems.
