2017 Map of Bighorn

About this map

The confluence of the Bighorn River and the Yellowstone River serves as the focal point of this Montana landscape, where the town of Bighorn sits near the crossing of Old Hwy 10. The terrain is defined by wide river bottoms and intricate coulees, with irrigation infrastructure such as the Bighorn Tullock Ditch and Victory Ditch supporting agricultural activity in the lowlands. Extensive island formations, including Government Island, and natural landmarks like Guys Bluffs characterize the winding waterway. The map captures a transition from the level terrain of Pease Bottom and Big Ox Bottom to the rising breaks of Jacobs Coulee and Petes Coulee. This layout reflects a region shaped by both water-rights engineering and the historical transportation corridors that followed the river valleys through Treasure and Yellowstone Counties.
