1991 Map of Overwhich Falls

About this map

Overwhich Falls serves as a central landmark in this high-altitude landscape where the Bitterroot National Forest meets the Salmon National Forest. This 1991 provisional survey captures a remote wilderness straddling the Montana-Idaho state line and the border between Ravalli and Lemhi counties. The drainage network is complex, with Overwhich Creek and Straight Creek carving through the terrain towards the North Fork Salmon River system. Small alpine basins hold isolated water bodies like Capri Lake, Pass Lake, and Frog Pond Lake. This map is particularly useful for identifying the established Pack Trail routes that navigated the steep drainages of Hughes Creek and Nicol Creek before modern developments, providing a detailed look at the hydrology of the Bitterroot range's southern reaches.
