Arrowhead Ranch Pryor
Mountain Mustangs



The origins of this rare strain began in the 16th century with importation of horses to America by the Spanish explorer Hernando Cortez. They were small and sturdy and adapted easily to the area. Native Americans captured them and used them in battle. Sure footed and fleet, they were also used by early cowboys to gather longhorn cattle. The Pony Express used them for there endurance.

Eventually, some Spanish Horses escaped and formed herds roaming in the west. Other horses escaped from early settlers and the mustang herd flourished. Eventually, they encroached on farmers land and paid for this with their lives. By mid-20th century, all wild herds faced extinction as mustangs were cruely shipped to slaughter.

Thanks to Wild Horse Annie (Velma Johnson), the Mustang made a comeback but now the herds of the Spanish Mustang had dwindled. During the 70's, wild horse specialists from the Bureau of Land Management discovered a group of horses with the color, conformation and primitive markings of the pure spanish Mustang. Genetic testing performed at the University of Kentucky confirmed that this group, now living on the Pryor Mountain range on the Montana and Wyoming border, in fact were decendents from those used by early Spanish Explorers. In 1992, the Pryor Mountain Mustang Breeders Association was formed to preserve and promote the Spanish strain.

The University of Kentucky has blood tested almost 200 of these Pryor Horses. Dr. Gus Cothran, head of the Blood Typing Research Laboratory, says: "The QAC variant is suggestive that the Pryor Mountain Wild horse herd is derived from old "Spanish" stock. The combination of evidence points to almost certain "Spanish" origins of the Pryor horses. This may be the most significant wild horse herd remaining in the United States."

Dr. Phil Sponenberg of Virginia Technical Veterinary College, and Chairman of the "Breeds Conservancy in the U.S." says: "The Pryor Mountain wild horse herd is the single most Spanish of the feral horse herds in the U.S.A. at this time."

Dr. Frank Singer of the "National Biological Survey" team, and from Colorado State University says: "I am amazed at the similarity of the Pryor horses, with few exceptions, to the Spanish Paso fino horses which I have." He also is doing blood work on the Pryor horses.

Dr. Jay Kirkpatrick of Zoo Montana and a man who has studied wild horses throughout the U.S. and, in fact, the world, says: "The Pryor horses are a very unique primitively marked type of horse and well worth saving."

Vicki Ives Speir, past Chairman of the National Indian Horse Registry and one of only five approved Indian horse judges in the world, has seen the Pryor horse and says: "The Pryor horses are one of the most unique "Northern type" of Spanish horses I have seen".

Mr. Charles Williamson, Forest Ranger on the Pryor Mountains (ca.1922) says in a letter dated 1967: "There were about 70 head of the genuine little Spanish horses in the remote and almost inaccessible canyons. I did not try to get them and neither did anyone else."
This letter is in my files.

The Pryor Mountain horses are a very unique National treasure. It is about time the people join together to preserve them before they too, are lost. These horses are one of the few remaining of the type of horse that roamed our country by the millions at one time.

"Mustang Sunrise" which is on display in the exhibit.
"At the heart of every western classic lives the hope that somewhere in the great american countryside there is a hidden valley where a herd of mustangs will
roam forever wild, proud, and free. "Mustang Sunrise" photographed at the
Arrowhead Ranch, is a moment's glimpse into one of those rare but swiftly
vanishing places, where some of the last of
America's Pryor Mountain Mustangs make their home."
