About this map

The Salmon National Forest dominates the rugged northern and western portions of this 1987 survey, where high-altitude drainages like Mollie Gulch and Stroud Gulch descend toward the valley floor. Resource extraction is evident along the slopes of Mineral Hill, where several Prospects and a Mine Shaft are noted, indicating a history of mineral exploration in the Idaho backcountry. The landscape transitions from these steep forest lands to a broad basin where the Lemhi River meanders, supported by an intricate network of irrigation ditches and canals that define the local agricultural layout.

Water management is central to the area's development, as seen in the presence of a Fish Hatchery and numerous labeled water sources such as Milk Creek, Adams Creek, and Eightmile Creek. Numerous Gravel Pit locations suggest ongoing infrastructure needs, while the presence of an Adit near the forest boundary points to legacy mining activity. The map captures a moment in the late twentieth century when the traditional economy of ranching and mining operated alongside protected federal lands in Lemhi County.
