The Sacagawea River winds through this expanse of Petroleum County, carving a distinct path through the dry breaks of central Montana. The landscape is defined by its deep drainages and coulees, including Hanson Coulee and Spring Coulee in the north, while Lane Coulee and the headwaters of Drag Cr mark the southern reaches. This modern topographical study captures a rugged ranching and hunting territory where human presence is mostly limited to primitive routes like Horse Camp Trl and the winding path of Crooked Creek Rd. The map illustrates a high-desert terrain shaped by seasonal water flow, providing a clear record of the area's physical geography and the sparse network of tracks used by those navigating this part of the Missouri River watershed.
