About this map

Dahl Lake sits at the heart of Pleasant Valley, a long topographic depression cutting through the heavily timbered lands of northwest Montana. This 1964 survey, updated through the early 1980s, captures the boundary between the Kootenai National Forest and the Flathead National Forest, where the border between Lincoln and Flathead Counties follows the high ridges. The landscape is defined by its drainages, including Coniff Creek and Meadows Creek, which flow toward the central valley basin.

Evidence of human activity is primarily limited to resource management and passage. A remote Gravel Pit and several Pack Trails underscore the isolation of the area. Named landmarks like Lemonade Spring and a distinctive terrain feature known as the Elbow provide specific points of reference for those navigating this expanse of the Northern Rockies. The map preserves the hydrological state of the valley floor before modern shifts in drainage or forest cover.
