2023 Map of Gilmore

About this map

Gilmore sits at the edge of the high mountain terrain where the Lemhi Range meets the valley floor, serving as the primary human footprint in this high-altitude interior. This 2023 survey by the U.S. Geological Survey details the complex topography of the Salmon National Forest and Challis National Forest, highlighting a landscape defined by dramatic peaks like Negro Peak and Portland Mtn. The settlement’s history is anchored by the Gilmore Cem, while the surrounding wilderness is etched with a network of resource-access routes such as the Silver Moon Gulch RD and the Long Canyon Main RD. Water is scarce but vital, found in high alpine basins like Meadow Lake and Mill Cr Lake. The terrain is deeply fissured by numerous gulches, including Sourdough Gulch, Shorty's Gulch, and Federal Gulch, which suggest a legacy of prospector exploration and seasonal livestock movement throughout the range.
