How many acres is the Horse Range that was established by Congress in Bighorn Canyon National Recreation Area?
Bighorn Canyon National Recreation Area Bighorn Canyon National Recreation Area is a national park unit established by an act of Congress on October 15, 1966, following the construction of the Yellowtail Dam by the Bureau of Reclamation. It straddles the border between Wyoming and Montana. The dam, named after the famous Crow leader Robert Yellowtail, harnesses the waters of the Bighorn River by turning that variable watercourse into Bighorn Lake. The lake extends 71 mi through Wyoming and Montana, 55 mi of which lie within the national recreation area. About one third of the park unit is located on the Crow Indian Reservation. Nearly one-quarter of the Pryor Mountains Wild Horse Range lies within the Bighorn Canyon National Recreation Area.

The Grassland ranges in elevation from 3600 ft to 5200 ft , and the climate is semi-arid. The Grassland provides opportunities for recreation, including hiking, sightseeing, hunting, and fishing. There are no developed campgrounds; however, camping is allowed. The Grassland abounds with wildlife year-round, provides forage for livestock, and is underlain with vast mineral resources. Land patterns are very complex because of the intermingled federal, state, and private lands.
