Bighorn Basin

Quick Facts
  • Located in northwestern Wyoming, the Bighorn Basin is formed by the Bighorn Mountains to the east, the Owl Creek Mountains to the south, and the Absaroka Mountains to the west.
  • The Bighorn Basin is vast, larger than Connecticut and Delaware combined. It is arid; most of the Basin receives between six and 10 inches of precipitation annually. Irrigated communities create small corridors of greenery in the arid badlands.
  • Archaeological evidence indicates human habitation of the Basin goes back 10,000 years.
  • Difficult terrain made the Basin one of the last parts of Wyoming to be settled. Summits in the Bighorn Mountains and the Absaroka Mountains extend over 13,000 feet.
  • John Colter came through the area in 1807. The first baseball game in the Basin was staged in 1870 by a mining expedition camped on the Greybull River.
  • The four counties which contain the Basin cover 14,323 square miles. Their total population is approximately 42,000 people.
