Henrys Lake anchors this high-elevation region where the border between Idaho and Montana follows the crest of the Continental Divide. The map details a landscape transition from the expansive water of the lake to the prominent heights of Targhee Peak and Black Mtn. Human settlement is concentrated primarily along the northern shoreline and through the mountain passes, characterized by established properties like the Wild Rose Ranch, Johnson Ranch, and Webster Ranch.
