2017 Map of Opal Lake

About this map

Salmon National Forest defines the topography of this Idaho wilderness, where the high country is broken by several prominent basins and steep drainages. The Panther Creek Rd provides the primary corridor through the terrain, following the course of Panther Cr and serving as a lifeline for those navigating the remote interior. The map reveals a series of named alpine basins including McGowan Basin, Moyer Basin, Prairie Basin, and Rooker Basin, which likely served as seasonal landmarks for grazing or early forest management. High-altitude water sources are critical features here, notably the small Opal Lake and the reliably named Bull Spring. For those tracing the history of land use in Lemhi County, the presence of Sawmill Gulch and Treloar Gulch suggests early localized industrial activity or family-named landmarks tied to the development of the region's natural resources.
