1964 Map of Yellowtail Dam

About this map

Yellowtail Dam stands as the central engineering marvel of this mid-1960s landscape, holding back the waters of the Yellowtail Reservoir as it snakes through Bighorn Canyon. This era represents a significant transformation of the Bighorn River valley, where newly established infrastructure like the Yellowtail Afterbay Dam, a Substation, and Sewage Disposal Ponds contrast with the area's deeper history. The presence of the Fort Smith Ruins near the modern settlement of Fort Smith highlights the strategic importance of this river crossing over time.
