The Butte County Courthouse and Historic Jail sit east of Belle Fourche's centre and give a more formal face to the town's county-seat role. The complex is a useful stop for anyone trying to understand how ranching towns on the edge of the Black Hills became administrative centres.
The surrounding area is quiet, so fold it into a broader Belle Fourche stop rather than treating it as a major destination. Its appeal is in the local history and the sense of scale: government built for a vast, thinly populated county.
