Powder River Country, Geographic region in northeastern Wyoming, United States.
Powder River Country is a large region in northeastern Wyoming, spreading across expansive rolling grassland plains. The area is characterized by open landscapes and several geographic features shaped by its geological development over time.
The region became central to westward expansion in the 1800s, serving as hunting grounds for Lakota Sioux and Northern Cheyenne tribes. Settlement and economic development later transformed the area as people moved in and established ranching and other industries.
The region remains deeply tied to its past as hunting grounds for Native American tribes, and this heritage shapes how local communities view themselves today. Museums and ranching traditions keep these stories alive for residents and visitors.
The region is best explored by car, as the area is large and sparsely populated with few towns in between. Visitors should prepare for changing weather conditions common to open plains areas.
The area sits above coal deposits that formed millions of years ago when this land was covered by a shallow sea. These buried resources now drive much of the economic activity visitors encounter in the region today.
