250px-Nokota_HorsesThe Nokota horse has an angular frame with prominent withers, a sloped croup, and a low set tail. Members of the breed are often blue roan, which is a color rare in other breeds, although black and gray are also common. Other, less common, colors include red roan, bay, chestnut, dun, grullo and palomino. Pinto patterns such as overo and sabino occur occasionally. There are two general types of the Nokota horse. The first is the traditional Nokota, known by the registry as the National Park Traditional. They tend to be smaller, more refined, and closer in type to the Colonial Spanish Horse, and generally stand between 14 and 14.3 hands (56 to 59 inches, 142 to 150 cm) high. The second type is known as the ranch-type or National Park Ranch, more closely resemble early "foundation type" Quarter Horses, and generally stand from 14.2 to 17 hands (58 to 68 inches, 147 to 173 cm). Members of the breed often exhibit an ambling gait, once known as the "Indian shuffle." Nokota horses are described as versatile and intelligent. Members of the breed have been used in endurance racing and western riding, and a few have been used in events such as fox hunting, dressage, three day eventing and show jumping. The Nokota derives its name from the Nokota Indian tribe that inhabited North and South Dakota.
