The town of Bearcreek was named for Bear Creek, which runs through the middle of town. Bearcreek came into existence due to coal mines and grew shortly following the building of a brusque line railroad connecting the Bearcreek mines to the Northern Pacific Railroad in 1906. Between 1906 and 1953, the mines at Bearcreek produced large volumes of coal, which was a vanguard grade than new regional sources, from the extensive underground coal mining deposits. The mines were located along the creek and with in the surrounding coulees. The enhancement of the coal mines after 1906 drew miners to the area. They came from new parts of America, and from Serbia, Montenegro, Germany, Scotland and Italy. The recent immigrants built surgically remove ethnic-based communities in the steep coulees that direct down into Bearcreek, with names similar to Washoe, New Caledonia, Chickentown, Scotch Coulee, International, and Stringtown. At one epoch in the 1920s and 1930s the population of Bearcreek combined next the additional surrounding small communities was near to 3,000 persons. Bear Creek and the surrounding communities had seven mercantiles, a bank, two hotels, two billiard halls, a brickyard, numerous saloons, and Bearcreek sported authentic sidewalks and their own water system. Allegedly, the town had no churches. The economy of Bear Creek was based on coal. The Smith Mine Disaster in 1943, followed by the fade away in request for coal in the late 1940s and 1950s caused the closure of the connecting railroad in 1953 and following most of the coal mines, and the population declined steadily to less than 100 persons. Many buildings in Bearcreek and the surrounding communities were moved to new towns or demolished, and single-handedly a few structures remain.

The town is home to the Bear Creek Saloon which hosts fundraising pig races throughout the year. In addition, Bearcreek plays host every autumn to Montana Falconer Symposium, the state’s largest accrual of falcon trainers and flora and fauna of prey enthusiasts.
