2013 Map of Opal Lake

About this map

Salmon National Forest defines the rugged geography of this Lemhi County landscape, where deep gulches and basins dictate the path of travel. The settlement at Forney sits near the northern boundary, serving as a focal point for the surrounding canyon network. Long-standing land use is evident through the presence of established homesteads such as Merritt Ranch and Kingsbury Ranch, positioned along the drainage of Panther Cr. The terrain is characterized by a series of high-elevation depressions, including Moyer Basin, Prairie Basin, and Rooker Basin, which are connected by forest service routes like Nat For Dev Rd 383. Moving toward the southeast, the landscape rises toward the namesake Opal Lake, the headwaters for several mountain streams including Opal Cr and Weasel Cr. This modern survey provides a clear view of the drainage patterns and historical ranching sites within the interior of Idaho's wilderness.
