The scenic Bighorn Basin and world-class fishing opportunities on the Bighorn River have made Big Horn County, Wyo., a tourist destination, but the area is also rich in oil and natural gas—and history. People have lived in the area since ancient times, as evidenced by the Medicine Wheel near the county’s northern corer. Ranch families still raise cattle and sheep, and farm families still raise sugar beets as they have for more than a century.
Boysen Dam, named for local businessman Asmus Boysen, was constructed on the Wind River in the 1940s to control flooding and to provide irrigation water for agricultural purposes. The dam was completed in early 1953 and its power plant continues to generate electricity today. Boysen Reservoir provides recreational opportunities as well.
