Crook County, Wyoming

Crook County sits in the northeastern corner of Wyoming and takes its name from General George Crook. The area was once at the center of Wyoming’s early oil boom, but today, life here is much quieter and more laid-back.

Ranching and timber are the mainstays of the local economy. The landscape blends rolling grasslands with thick pine forests, while the towering Devils Tower stands out on the horizon. The landmark holds deep spiritual importance for many Native American tribes and attracts visitors from all over.

Sundance, the county seat, is full of Old West history and gave the famous Sundance Kid his nickname after he was jailed there. Winters can be long and bitterly cold, but spring brings colorful wildflowers across the countryside. With a small population spread across a large area, Crook County offers a slower, quieter way of life—and locals are perfectly happy with that.
