The settlement of Ellis serves as the focal point for this high-desert landscape where the Salmon River meets the Pahsimeroi River along the border of Custer and Lemhi Counties. The map illustrates a ranching and conservation corridor centered on the Pahsimeroi Valley, where localized water sources such as Magpie Spring and Anderson Spring have long supported settlement. Human impact and access are clearly defined by naming conventions for the terrain, including Cronks Canyon and the notable Eagle Rock formation. Infrastructure for the local ecosystem is visible at the Pahsimeroi Rearing Ponds, while designated points like the Deer Gulch Access Area and Ellis Access Area highlight the importance of river access. The layout of rural routes such as Ennis Gulch Rd and Bursteadt Ln trace the historical development of family lands and homesteads nestled between the gulches and the major river forks.
