H-T Ranch is a historic ranch complex 10 mi west of Amidon, North Dakota.
 The ranch originally consisted of ten buildings; however, only the ranch house and log barn survive.
 The ranch served as the headquarters of the Little Missouri Cattle Company, which was run by Arthur Clark Hidekoper.
 Hidekober established the ranch in the 1880s, and by the end of the decade, it had become the "most notable" ranch in the area.
 The ranch house, called Shackford, was built in 1896; its uncommon style resembles a bungalow but also borrows from other styles such as the Stick style.
 By 1906, the "Fargo Forum" described the ranch as "the biggest and most important [ranch] in the state" and "one of the largest horse raising outlets in the world".
 In the same year, Hidekoper sold the 70,000 acre ranch; the sale was the largest land deal in North Dakota history.
 After the sale, a land company reduced the ranch to 5000 acre ; it was later used as a dude ranch in the 1920s.
The CCC Ranch Headquarters is a historic ranch headquarters in Texhoma, Oklahoma.
 The headquarters site consists of a ranch house and bunkhouse located along the Beaver River.
 Built circa 1880, the ranch headquarters served the CCC Ranch, the largest ranch in the Oklahoma Panhandle from 1890 to 1901.
 The ranch, owned by a group from Tombstone, Arizona, covered 90 mi2 from Texhoma to Boise City at its peak.
 Like the other ranches in the area, the CCC Ranch shrank as homesteaders settled its land; its headquarters are the only intact ranch headquarters in the Panhandle, and the buildings now represent the cowboy era of the American West.
The White Grass Dude Ranch is located in the White Grass Valley of Grand Teton National Park.
 The rustic log lodge, dining hall service building and ten cabins were built when a working ranch was converted to a dude ranch, and represented one of the first dude ranch operations in Jackson Hole.
 The White Grass was established in 1913 by Harold Hammond and George Tucker Bispham, who combined two adjacent ranches or 160 acre each, and was converted to a dude ranch in 1919.
 Bispham had worked at the Bar B C before moving out on his own.
 The dude ranch operation continued to 1985, when the ranch was acquired by the National Park Service.
The Chico Basin Ranch is a working cattle ranch thirty minutes southeast of Colorado Springs, Colorado.
 The Chico Basin is owned by the Colorado State Land Board, and managed by Ranchlands, Duke and Janet Phillips' family based ranch management company.
 The cattle raised on the ranch are grass fed and no hormones added.
 Working cowboys tend to the cattle primarily using quarter horses born and trained on the ranch.
 The Chico Basin now has a horse sanctuary for old or injured horses.
 Not only is the Chico Basin a working cattle ranch, it is also a wildlife preserve.
 The Chico Basin works with the Rocky Mountain Bird Observatory to band migratory birds.
 This activity is also open to schools and universities to come and learn about birds.
 Free programs are offered to all ages of children and adults to learn about wildlife and ranch life.
The Percheron is a breed of draft horse that originated in the Huisne river valley in western France, part of the former Perche province from which the breed takes its name.
 Usually gray or black in color, Percherons are well muscled, and known for their intelligence and willingness to work.
 Although their exact origins are unknown, the ancestors of the breed were present in the valley by the 17th century.
 They were originally bred for use as war horses. Over time, they began to be used for pulling stagecoaches and later for agriculture and hauling heavy goods.
 In the late 18th and early 19th centuries, Arabian blood was added to the breed.
 Exports of Percherons from France to the United States and other countries rose exponentially in the late 19th century, and the first purely Percheron stud book was created in France in 1883.
The Bar U Ranch National Historic Site, located near Longview, Alberta, is a preserved ranch that for 70 years was one of the leading ranching operations in Canada.
 At its peak, the ranch extended over 160000 acre with 30,000 cattle and 1000 Percheron horses.
 Two owners were instrumental in the establishment of the Calgary Stampede, forming part of the Big Four.
NAN Ranch, also known as Y Bar NAN Ranch, is a ranch in Faywood, New Mexico, that was added to the National Register of Historic Places in 1988.
 The property was developed as a ranch beginning in the late-1860s by John Brockman, who grew corn, alfalfa, and several types of fruit and bred cattle.
 Cattleman John T. McElroy purchased the ranch in 1927 and hired Trost & Trost to renovate and expand the ranch compound to become the NAN Ranch headquarters.
 The project included a new house, extensive landscaping, swimming pool, a slaughterhouse, powerhouse, and other residential and ranch buildings.
 It is historically significant due to its architecture and its role as a major 19th century ranch.
Bertha Muzzy Sinclair or Sinclair-Cowan, "née" Muzzy (November 15, 1871 – July 23, 1940), best known by her pseudonym B. M. Bower, was an American author who wrote novels, fictional short stories, and screenplays about the American Old West.
 Her works, featuring cowboys and cows of the Flying U Ranch in Montana, reflected "an interest in ranch life, the use of working cowboys as main characters (even in romantic plots), the occasional appearance of eastern types for the sake of contrast, a sense of western geography as simultaneously harsh and grand, and a good deal of factual attention to such matters as cattle branding and bronc busting."
 She was married three times: to Clayton Bower in 1890, to Bertrand William Sinclair (also a Western author) in 1905, and to Robert Elsworth Cowan in 1921.
 However, she chose to publish under the name Bower.
The Cunningham Cabin is a double-pen log cabin in Grand Teton National Park.
 The cabin was built as a homestead in Jackson Hole and represents an adaptation of an Appalachian building form to the West.
 The cabin was built just south of Spread Creek by John Pierce Cunningham, who arrived in Jackson Hole in 1885 and subsisted as a trapper until he established the Bar Flying U Ranch in 1888.
 The Cunninghams left the valley for Idaho in 1928, when land was being acquired for the future Grand Teton National Park.
The Bar B C Dude Ranch was established near Moose, Wyoming in 1912 as a dude ranch by Struthers Burt and Dr. Horace Carncross, using their initials as the brand.
 Rather than converting a working ranch, Burt and Carncross built a tourist-oriented dude ranch from the ground up, using a style called "Dude Ranch Vernacular", which featured log construction and rustic detailing.
 As one of the first dude ranches in Jackson Hole, the Bar B C was a strong influence on other dude ranches in the area, and employed a number of people who went on to establish their own operations.
 It was acquired by the National Park Service and incorporated into Grand Teton National Park upon the expiration of a life estate.
 The ranch was listed on the National Register of Historic Places in 1990.
