Deer Lodge is the county seat of Powell County, Montana. The population was 3,111 at the 2010 census. The city is perhaps best known as the home of the Montana State Prison, a major local employer. More museums and historical collections can be found here than in any other town in the Northwest.
Deer Lodge’s 1,500-acre Grant-Kohrs Ranch National Historic Site illustrates the development of the northern plains cattle industry from the 1850s to recent times. This was the headquarters of one of the largest and best known 19th-century range ranches in the country.
Grant-Kohrs Ranch National Historic Site, dedicated to the interpretation of the frontier cattle ranching era. This site was the home of Conrad Kohrs, one of the famous “Cattle Kings” of Montana whose land holdings once stretched over a million acres (4,000 km²) of Montana, Wyoming, and Alberta, Canada. The Grant-Kohrs ranch was built in 1862 by Johnny Grant, a Scottish/French/Metis fur-trader and trapper who encouraged his people to settle in Deer Lodge because of its pleasant climate and large areas of bunchgrass prairie, ideal for raising cattle and horses.
Deer Lodge was also once an important railroad town, serving as a division headquarters for the Chicago, Milwaukee, St. Paul and Pacific Railroad (“the Milwaukee Road”) before the railroad’s local abandonment in 1980.
The current Montana State Prison occupies a campus 3.5 miles (5.6 km) west of town. The former prison site, at the south end of Deer Lodge’s Main Street, is now the Old Prison Museum. In addition to a former cell-block building, the museum complex includes a theater, antique and automobile museums, and a former Milwaukee Road “Little Joe” electric locomotive.
