About this map

Salmon sits at the confluence of several mountain drainages where the Salmon River flows northward through the Lemhi Valley. This modern topographical survey illustrates the town's position as a regional hub, anchored by the Lemhi County Courthouse and serving as a gateway to the expansive Salmon National Forest. The map detail captures the residential grid extending toward the City Cem, while the Lemhi County Airport provides critical access to this high-altitude landscape.

Mountainous terrain dominates the western portion of the quadrangle, rising toward the Salmon River Mountains and notable summits like Morning Glory Peak. Historically significant routes, including the Lewis and Clark Trl, follow the river corridor through Carmen and across the Big Flat. The intricate network of forest roads and trails, such as Old Leesburg Rd and the Nat For Dev Rd 082, underscores the area's ongoing relationship with the surrounding wilderness and its canyon features like Pollard Canyon.
