The Big Hole River winds through this section of Beaverhead County, defining a landscape shaped by high-altitude ranching and complex water management. An extensive network of irrigation infrastructure, including the Huntley-Ditch, Miller Ditch, and the aptly named Big Ditch, illustrates the historical effort to divert alpine runoff to the valley floor. In the eastern portion of the map, the terrain rises into the timbered slopes of the Beaverhead National Forest, where drainage features like Fox Gulch and Broomfield Gulch cut through the foothills.
