The confluence of the Teton River and the Missouri River defines the northern reaches of this landscape in Chouteau County. The terrain transitions from the low-lying river bottoms at Evans Bend and Shonkin Bar to the elevated northern terrace of Rowe Bench. To the south, the namesake O'Hanlon Coulee carves through the breaks, illustrating the complex drainage patterns typical of the region.
