Pryor Mountains National Forest was established as the Pryor Mountains Forest Reserve by the U.S. Forest Service in Montana on November 6, 1906 by the U.S. Forest Service with 78732 acre .  It became a National Forest on March 4, 1907.  On July 1, 1908 it was combined with part of Yellowstone National Forest to establish Beartooth National Forest.  The name was discontinued. The Pryor Mountains are a mountain range in Carbon and Big Horn counties of Montana.  They are located on the Crow Indian Reservation and the Custer National Forest, and portions of them are on private land.  They lie south of Billings, Montana, and north of Lovell, Wyoming. The Pryor Mountains Wild Horse Range is a refuge for a historically significant herd of free-roaming Mustangs, feral horses colloquially called "wild horses", located in the Pryor Mountains of Montana and Wyoming in the United States.  The range has an area of 39650 acre and was established in 1968 along the Montana–Wyoming border as the first protected refuge dedicated exclusively for Mustangs.  It was the second feral horse refuge in the United States.  About a quarter of the refuge lies within the Bighorn Canyon National Recreation Area.  A group of federal agencies, led by the Bureau of Land Management, administers the range. In Crow called Alaxchiiaahush / Alaxchíia Ahú (″Many War Achievements″), he is better known by his English name as Plenty Coups (a translation of his name, coming from the word coup, meaning "counting many coups (war achievements"); 1848 – 1932) was the "Ashbacheeítche" (″Chief Of The Camp″, band chief) of the Mountain Crow Band (Ashalaho/, later: Awaxaawaxammilaxpáake) of the Crow Nation (Apsáalooke), a visionary leader, and a great diplomat.

Dryhead Country is a region in Carbon County and Big Horn County in southern Montana between Bighorn Canyon and the Pryor Mountains.  The locale was named after the piles of dry bison skulls that accumulated at the base of a local buffalo jump.  The Dryhead region starts near the Wyoming border in Bighorn Canyon National Recreation Area and extends northward into the Crow Indian Reservation.  Dryhead Creek drains a portion of the area, falling eastwards into Bighorn Canyon.  The semi-arid basin is one of the most remote areas in Montana.  The area is sparsely populated with isolated ranches. 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 Pryor Mountain Mustang is a substrain of Mustang considered to be genetically unique and one of the few strains of horses verified by DNA analysis to be descended from the original Colonial Spanish Horses brought to the Americas by the Spanish.  They live on the Pryor Mountains Wild Horse Range located in the Pryor Mountains of Montana and Wyoming in the United States, and are the only Mustang herd remaining in Montana.  They are protected by the Wild and Free-Roaming Horses and Burros Act of 1971 (WFRHBA) and managed by the Bureau of Land Management (BLM), who has set the optimum herd number at 120 animals.  Genetic studies have revealed that the herd exhibits a high degree of genetic diversity and a low degree of inbreeding, and BLM has acknowledged the genetic uniqueness of the herd.  Pryor Mountain Mustangs are relatively small horses, exhibit a natural ambling gait, and domesticated Pryor Mountain Mustangs are known for their strength, sure-footedness and stamina.
