About this map

The Missouri River and its confluence area with the Teton River dominate this Chouteau County landscape, where the water has carved a complex network of breaks and bars. The northern portion of the map highlights Rowe Bench and the prominent Crocon du Nez, while the riverbed itself features distinctive landing points like Evans Bend and Shonkin Bar. These fluvial features speak to the historical importance of the river corridor for navigation and early transit.

Moving south, the terrain rises toward Frenchmans Ridge and is dissected by numerous coulees, including O'Hanlon Coulee and Early Coulee. The transportation network is defined by a mix of modern routes like MT-80 and local traces such as Stagecoach Trl and Rode School Rd, reflecting a legacy of ranching and rural movement across the high plains. Landmarks like Shaws Peak provide orientation across this sparsely settled but topographically diverse region.
