2013 Map of Long Valley

About this map

Hancock Ranch and the high basins of eastern Idaho define this landscape of high-altitude water management and volcanic geology. The presence of the Willow Creek Lava Field in the southern portion of the quadrangle highlights the region's recent geologic activity, contrasting with the numerous drainages such as Crane Cr and Sheep Cr that carve through the hills. Water is a central theme of this terrain, evident in the development of the Robison Reservoir and Parleys Reservoir, along with isolated sources like Dynamite Spring and Gold Spring. Prominent landmarks such as Mollies Nipple, Sheep Mtn, and the Three Buttes provide essential navigational points within the complex topography of the Long Valley. This mapping reveals a remote ranching and grazing territory where seasonal water flow and named terrain features like Cranes Flat dictate the use of the land.
