Ellis stands at the strategic confluence of the Salmon River and the Pahsimeroi River, serving as a focal point for this high-elevation mountain basin. The landscape is defined by the broad Pahsimeroi Valley, where early 21st-century irrigation and transport networks such as Pahsimeroi River Rd and Custer Rd follow the natural contours of the river banks. This survey shows the intricate drainage systems and canyons that feed the main river arteries, including Cronks Canyon to the north and the steep Deer Gulch.
