1968 Map of Swift Reservoir

About this map

Lewis and Clark National Forest dominates this high-altitude landscape, where the Eastern Front of the Rockies meets the Blackfeet Indian Reservation Boundary. The primary water feature is the Swift Reservoir, controlled by Spillway 4884 and fed by the converging waters of Birch Creek and its many tributaries, including North Fork Birch Creek and South Fork Birch Creek. The terrain is characterized by massive peaks and ridges, most notably Feather Woman Mountain, Mount Poia, and the sharp crest of the Backbone. This survey, field-checked in the late 1960s, documents a complex drainage system where Whitetail Creek and Haywood Creek carve through the foothills. Evidence of local geography and land use is found in labels like Killem Horse Creek and the high Mowitch Basin, illustrating the intersection of federal forest land and indigenous reservation territory.
