About this map

The Yellowjacket Mountains dominate this high-elevation landscape within the Salmon National Forest, where the settlement of Forney sits at the northern edge. The geography is defined by a series of deep drainages and basins, most notably McGowan Basin, Moyer Basin, and Rooker Basin, which collect the waters of Panther Creek and its many tributaries. This modern survey reflects the enduring importance of historical transit and resource access, highlighting the Thunder Mountain Historic Trl and various mountain routes like the Meyers Cove Road (Winter Trl).

Tracing the path of Opal Creek leads to the secluded Opal Lake, situated at the base of steep slopes. The map details a network of forest trails, including the Singheiser Trl and Opal Trl, providing a clear look at the access points used by researchers and outdoorsmen today. The drainage patterns of South Fork Moyer Creek and Silver Creek illustrate the complex water systems that have shaped the local topography of Lemhi County.
