About this map

Big Porcupine Cr carves a central path through this section of the Montana high plains, where the Garfield Co and Rosebud Co line marks the northern boundary of the map. The landscape is defined by its drainage patterns, featuring deeply etched coulees and a prominent landmark at Hole-in-the-Rock near the northern edge. Significant erosion has created complex terrain such as Devils Canyon and the neighboring Germo Coulee, which descend toward the eastern watercourses.

Transportation in this cattle-ranching and grazing country is limited to a few arterial paths, most notably Acorn Flats Rd and Shoup Rd. These routes connect remote homesteads and access points along Indian Cr and Acorn Cr. The map provides a precise look at the 2020 township and range system, specifically within T12N R36E and the adjacent townships, illustrating the vast open-range character of this part of the state.
