Big Lost River bisects the valley floor, defining the agricultural character of this central Idaho landscape. The small settlements of Leslie and Darlington serve as the primary human hubs, situated along a network of ranching roads like Leslie Rd and Fullmer Rd. This area reveals a sophisticated water management system critical to high-desert farming, featuring an extensive grid of irrigation infrastructure including the Blaine Canal, Three in One Ditch, and Angelo Ditch. To the west, the terrain rises sharply into the White Knob Mountains and Sheep Canyon, while the eastern portion provides access to the Challis National Forest. Local history is anchored at the Darlington Cem, while unusual geological features like the Darlington Sinks highlight the unique hydrology of the Big Lost River Valley.
