Since 1911, Musselshell County continues to be a strong piece of Montana history and the state's culture. The county's name comes from the Musselshell River that Lewis & Clark traveled, and today hosts over 4,600 residents and countless visitors each year. The largest city and county seat is Roundup, that received it's name from the historic cattle roundups dating back to the 1800's.

The local economy includes a lasting history of cattle ranching, coal mining, dry land farming, other rural agriculture, local businesses, coal, oil and gas, and a railroad service that now serves the current coal mine. In the 90's the coal industry came back online to grow an impressive production that employs 300 workers at today's Signal Peak Mine.
