Sheridan County

Sheridan County is an administrative county in northeastern Montana that spans plains and rolling hills along the borders with North Dakota and Saskatchewan, characterized by open farmland and wide spaces. The county is centered around the town of Plentywood, which serves as its administrative and economic hub.

The county was established in 1913 when the Montana Legislature divided portions of Dawson and Valley Counties, naming it after Civil War General Philip Sheridan. This creation reflected the administrative reorganization happening across Montana during the state's early development.

The region became known in the early 20th century as a center for socialist political movements, where local communities actively engaged with alternative political ideas. This distinctive history shaped how residents viewed themselves and continues to influence local identity today.

All local government services and administrative functions are headquartered in Plentywood, the county seat, making it easy to find official information. The flat to gently rolling terrain makes it simple to explore by car, with roads well maintained throughout the area.

Part of the Medicine Lake National Wildlife Refuge lies within the county, serving as a crucial stopping point and breeding ground for migratory birds traveling across North America. This refuge draws birdwatchers from across the region who come to observe waterfowl and other native species.
