The Sun River valley dominates this landscape, where the confluence with Muddy Creek near Vaughn highlights a complex irrigation and transport network in central Montana. The terrain is defined by a series of distinct plateaus known as Third Bench, Second Bench, and First Bench, which rise above the river bottoms. This mid-century survey captures the region's agricultural infrastructure, including the Greenfields Canal and Fort Shaw Canal, which divert water to the surrounding fields.
