Wyoming: Big Horn County

Big Horn County (pop. 11,668) is west across the Big Horn Mountains from Sheridan County and south across the Montana border from Big Horn County, Montana.

Basin (pop. 1,285), the county seat, got its name because it’s in the middle of the Bighorn Basin; the 461-mile Bighorn River (a tributary of the Yellowstone River) flows north through the area on its way to Montana.

Basin is the second-smallest county seat in Wyoming and only the third-largest town in Big Horn County. Both Lovell (pop. 2,360) and Greybull (pop. 1,847) are larger.

Greybull is the home of the outdoor Museum of Flight and Aerial Firefighting.

In Lovell, the Hyart Theater (1950) – with its unique exterior design – still has movies on Fridays and Saturdays.

In Cowley (pop. 655), the former Big Horn Academy (1916) is now used for school administrative offices.

It was Cowley High School for many years.

In the northern part of the county, the Bighorn Canyon National Recreation Area includes Bighorn Lake on the Bighorn River; the lake was created by construction of Yellowtail Dam in 1965.
