1960 Map of Hysham

About this map

Hysham serves as the focal point of this Treasure County landscape, situated along the southern banks of the Yellowstone River. The area’s agricultural character is defined by an intricate network of irrigation infrastructure, including the Yellowstone Canal, Hysham Main Canal, and Box Elder Ditch, which redirect water into the dry terrain of Mission Valley. This reliance on the river and its diverted channels highlights the transformation of the prairie into productive farmland during the mid-20th century.
