2020 Map of Thebes

About this map

Big Porcupine Rd and Cohagen Rd cross this part of Rosebud County, marking the sparse transit network of the high plains north of the Yellowstone River. The terrain is defined by the drainage patterns of Big Porcupine Cr and W Blacktail Cr, which carve into the landscape to form distinct coulees like Blind Coulee and Sun Coulee. While the map reflects the modern landscape as of 2020, the arterial naming of Petroleum Rd suggests the enduring influence of regional energy development on the local geography. This area is characterized by large township grids and open range, where topographic variations are primarily found along the edges of these water-carved depressions.
