Bighorn River, River in Wyoming and Montana, United States.
The Bighorn River is a waterway stretching roughly 460 km (286 miles) through Wyoming and Montana, beginning as the Wind River in the Rocky Mountains. It flows through mountainous and open terrain with several access points where visitors can reach the water and explore the surrounding landscape.
A French fur trader gave the river its name in 1805 after observing many bighorn sheep grazing on its banks during early exploration of the region. The name has remained unchanged and continues to reflect the wildlife that characterized the area when early visitors first arrived.
The Crow people call this waterway Iisaxpúatahcheeaashisee in their language, a name that refers directly to the large bighorn sheep that once roamed here. The name shows how central these animals were to those who lived on the land long before others arrived.
Visitors can reach the river at several public spots, especially in the upper section where parking and river access are available. The best time to visit depends on what you plan to do, so check local conditions beforehand to match them with your activities.
At a location called Wedding of the Waters, the Wind River suddenly transforms and takes on a new name as it continues downstream. This transition point shows how a river can change its identity while remaining one continuous flow of water.
