The confluence of three major waterways—the Marias River, Teton River, and Missouri River—dominates this northern Montana landscape. At this historic junction, the settlement of Loma serves as the focal point, connected to the surrounding plateaus by the Loma Bridge and a network of rural routes like Loma Ferry Rd. The terrain is defined by dramatic elevation changes, where high flats like Rowe Bench and the prominent Vimy Ridge give way to deeply eroded drainages including Fisher Coulee and Dry Fork Coulee. Along the Missouri River at the southern edge, sandbars and distinctive landforms such as Brule Bar and Crocon du Nez reveal the shifting hydrology of the riverbanks. This 2017 survey details a landscape where traditional agricultural benchlands meet the complex breaks of the Missouri River system.
