2017 Map of Hole-in-the-Rock

About this map

Hole-in-the-Rock serves as the namesake landmark for this stretch of the northern plains along the boundary of Rosebud and Garfield Counties. The landscape is defined by the complex drainage systems of Big Porcupine Cr and Indian Cr, which have carved deep into the terrain to form significant natural features such as Devils Canyon. Further east, the drainage of Acorn Cr continues this pattern of erosion, creating a network of landforms including Hanson Coulee and Germo Coulee. Human presence is sparse in this 2017 snapshot, marked primarily by rural routes such as Shoup Rd and Acorn Flats Rd. The map illustrates the intersection of Township and Range lines T13N, T12N, R35E, and R36E, providing a clear record of the cadastral grid overlying this varied Montana topography.
