The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula). The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less precipitation than that of the tall and mixed grass prairies to the east.

Lying largely in the rain shadow of the mountains to the west, the prairie includes lands in the eastern foothills of the Rocky Mountains and extends east as far as Nebraska and north into Saskatchewan. The prairie stretches through parts of Alberta, Wyoming, Montana, North Dakota, South Dakota, and Kansas, and passes south through the high plains of Colorado, Oklahoma, Texas, and New Mexico.

Glyptotherium (from Ancient Greek for 'grooved or carved beast') is a genus of glyptodont (an extinct group of large, herbivorous armadillos) in the family Chlamyphoridae that lived from the Early Pliocene, about 3.9 million years ago, to the Late Pleistocene, around 15,000 years ago. It was widely distributed, living in the United States, Mexico, Guatemala, Costa Rica, Honduras, El Salvador, Panama, Venezuela, Colombia, and Brazil. Fossils that had been found in the Pliocene Blancan Beds in Llano Estacado, Texas were named Glyptotherium texanum by American paleontologist Henry Fairfield Osborn in 1903. Another species, G. cylindricum, was named in 1912 by fossil hunter Barnum Brown on the basis of a partial skeleton that had been unearthed from the Pleistocene deposits in Jalisco, Mexico. The two species differ in several aspects, including age: G. texanum is from the older Early Pliocene to Early Pleistocene strata, whereas G. cylindricum is exclusive to the Late Pleistocene.

Glyptotherium was a large, four-legged (quadrupedal), herbivorous armadillo with an armored top shell (carapace) that was made of hundreds of interconnected osteoderms (structures in dermis composed of bone). Other pieces of armor covered the tail and cranium roof, while small pebbly pieces of armor were in the skin. Glyptotherium grew up to 2 meters (6.56 feet) in length and 400 kilograms (880 pounds), making it one of the largest glyptodonts known. Glyptotherium is morphologically most similar to Glyptodon: though they differ in several ways. Glyptotherium is smaller on average, with a shorter carapace, a longer tail, and had a different distribution.

The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. The High Plains are located in eastern Montana, southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico, the Oklahoma Panhandle, and the Texas Panhandle. The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or on satellite maps. From east to west, the High Plains rise in elevation from around 1,500 to 6,000 ft (460 to 1,830 m).

Eastern New Mexico is a physiographic subregion within the U.S. state of New Mexico. The region is sometimes called the "High Plains", or "Eastern Plains (of New Mexico)", and was historically referred to as part of the "Great American Desert". The region is largely coterminous with the portion of the Llano Estacado in New Mexico. Portions of Eastern New Mexico's elevation extend to over 4,000 ft (1,200 m). The region is characterized by flat, largely featureless terrain with the exception of the Pecos River valley and the abrupt breaks along the Mescalero Ridge and northern caprock escarpments of the Llano Estacado. The region typically lacks the high relief of central and northern New Mexico, such as that in the Sangre de Cristo and Sandia mountain ranges. The climate is semi-arid with hot summers and is characterized by significant wind and dust storms in the springtime.

Like much of the Llano Estacado region, Eastern New Mexico is largely rural and agricultural, and resembles West Texas in geography, economy, and demographics. The population is sparse as compared to the rest of the country. The region includes portions of the counties of Curry, De Baca, Guadalupe, Lea, Quay, and Roosevelt. It is served by Eastern New Mexico University, a state university located in Portales, and the Blackwater Draw archaeological site is located there.

Lubbock (/ˈlʌbək/ LUB-ək)is a city in the U.S. state of Texas and the county seat of Lubbock County. With a population of 272,086 in 2024, Lubbock is the 10th-most populous city in Texas and the 84th-most populous in the United States. The city is in the northwestern part of the state, in the Great Plains region, an area known historically and geographically as the Llano Estacado, and ecologically is part of the southern end of the High Plains, lying at the economic center of the Lubbock metropolitan area, which had an estimated population of 367,109 in 2024.

Lubbock's nickname, "Hub City", derives from it being the economic, educational, and healthcare hub of the multicounty region, located north of the Permian Basin and south of the Texas Panhandle, commonly called the South Plains. The area is the largest contiguous cotton-growing region in the world and is heavily dependent on water from the Ogallala Aquifer for irrigation.

The vaquero (Spanish: [baˈkeɾo]; Portuguese: vaqueiro, European Portuguese: [vɐˈkɐjɾu]) is a horse-mounted livestock herder of a tradition that has its roots in the Iberian Peninsula and extensively developed in what is today Mexico (then New Spain) from a method brought to the Americas from Spain. The vaquero became the foundation for the North American cowboy, in Northern Mexico, Southwestern United States, Florida and Western Canada.

The cowboys of the Great Basin still use the term "buckaroo", which may be a corruption of vaquero, to describe themselves and their tradition. Many in Llano Estacado and along the southern Rio Grande prefer the term vaquero, while the indigenous and Hispanic communities in the age-old Nuevo México and New Mexico Territory regions use the term caballero. Vaquero heritage remains in the culture of Mexico (Especially in Northern Mexico), along with the Californio (California), Neomexicano (New Mexico), Tejano (Texas), Central, and South America, as well as other places where there are related traditions.
