The Missouri River meanders across this landscape at the intersection of Roosevelt, McCone, and Valley counties, marking a significant hydrologic and historical boundary. This 2020 survey illustrates the complex drainage network of northeastern Montana, where the Flynn Cr and its E Fork Flynn Cr join the river system near the iconic Lewis and Clark Trl. The geography is defined by its coulees and seasonal watercourses, including Steele Coulee and Spring Coulee, which carve through the plains. Tribal and local infrastructure is evident through the presence of Indian Hwy and several Bureau of Indian Affairs routes like BIA Rte 1. Other notable waterways such as Oswego Cr and Littleman Cr further illustrate the terrain's reliance on these vital drainage patterns.
