2020 Map of Pompeys Pillar

About this map

Yellowstone River currents define the northern boundary of this region, where the historic settlement of Pompeys Pillar stands as a focal point for the surrounding rural landscape. The terrain south of the river is characterized by complex drainages and elevation changes, managed in part by irrigation infrastructure like the Huntley Main Canal. This 2020 survey illustrates the modern layout of these long-established agricultural corridors and transportation routes as they follow the natural contours of the valley. The map provides a detailed look at the interface between the river's riparian zone and the higher ground to the south, reflecting the ongoing importance of water management in the development of this section of Montana.
