About this map

The Yellowstone River dominates this mid-century landscape in Yellowstone County, Montana, carving a wide path through the prairie terrain. At the center of this reach lies Big Marys Island, a large landform situated within the river's main channel. The map illustrates the sophisticated water management and transportation systems that defined the region's development during the late 1960s, including the Pacific Clark and Lewis Main Canal and the Northern Pacific railroad line.
