2017 Map of Long Valley

About this map

The Willow Creek Lava Field dominates the southwestern portion of this Idaho landscape, where the basaltic flows meet the high-altitude drainage systems of the Caribou Range. Water is the primary defining feature of this 2017 survey, with an intricate network of seasonal flows and managed water sources including Robison Reservoir and Parleys Reservoir. The terrain is marked by distinctive geological formations such as the steep Mollies Nipple and the broad The Basin, reflecting the complex volcanic and erosional history of Bingham County. Local travel is facilitated by Long Valley Rd and Bone Rd, which navigate the undulating topography between Outlet Ridge and the Pack Saddle Basin. The abundance of named springs, such as Dynamite Spring and Gold Spring, indicates the critical importance of these water points for livestock and land management in this high-desert environment.
