About this map

The Big Lost River Valley forms a broad agricultural corridor at the base of the Lost River Range, where early water management infrastructure was essential for settlement. The valley floor is crisscrossed by irrigation features like the Moore Diversion and various segments simply labeled Ditch, which carry water from the Big Lost River to the surrounding fields. Local history is anchored by the Pioneer Cem near the riverbanks, marking the presence of early inhabitants who worked this land before the era of modern utility infrastructure, such as the Substation and Storage Bin now seen along Moore Road.

To the east, the terrain rises sharply into the Challis National Forest, defined by a series of deep drainages including Ramshorn Canyon, Limekiln Canyon, and King Canyon. These canyons descend from peaks like King Mountain, illustrating the stark transition between the irrigated valley floor and the high alpine desert. Primitive access routes like the Beck and Evan Ditch Road and several Jeep Trails provide a record of how this backcountry was navigated for ranching and resource management.
