Crowley Dam anchors this central Montana landscape, where the high plains of Petroleum County meet the northern border of Musselshell County. The terrain is defined by its deep drainage patterns, specifically the winding courses of Alkali Cr and Howard Cr. These waterways cut through the arid topography, creating the distinct geological depressions of Howard Coulee and Jim Coulee. The sparse road network, consisting primarily of Flatwillow Rd and Kelley Rd, reflects the area's transition into remote rangeland. The map clearly delineates the complex Public Land Survey System (PLSS) grid, showing the intersection of multiple townships including t12n r27e and t13n r27e, which is essential for understanding historical land claims and modern property boundaries in this sparsely populated region.
