Palo Duro Canyon is a canyon system of the Caprock Escarpment located in the Texas Panhandle near the cities of Amarillo and Canyon. As one of the largest canyons in the United States, it is roughly 25–40 mi (40–64 km) long and has an average width of 6 mi (9.7 km), but reaches a width of 20 mi (32 km) at places. Its depth is around 800 ft (240 m), but in some locations, valley bottom to surrounding hills increases to 1,000 ft (300 m). Palo Duro Canyon has been named "The Grand Canyon of Texas" both for its size and for its dramatic geological features, including the multicolored layers of rock and steep mesa walls, which are similar to those in the Grand Canyon. It is part of Palo Duro Canyon State Park. The State Park had 442,242 visitors in 2022.
The Texas panhandle is a region of the U.S. state of Texas consisting of the northernmost 26 counties in the state. The panhandle is a square-shaped area bordered by New Mexico to the west and Oklahoma to the north and east. It is adjacent to the Oklahoma Panhandle, land which Texas previously claimed. The 1820 Missouri Compromise declared no slavery would be allowed in states admitted from the Louisiana Purchase above 36°30′ north latitude. Texas was annexed in 1845 from still more westerly land. The Compromise of 1850 removed territory north of this line from Texas, and set the border between the Texas Panhandle and the New Mexico Territory at the 103rd meridian west. The eastern border at the 100th meridian west was inherited from the Adams–Onís Treaty of 1819, which defined the border between the United States and New Spain. The Handbook of Texas defines the southern border of Swisher County as the southern boundary of the Texas Panhandle region.
The Llano Estacado, sometimes translated into English as the Staked Plains, is a region in the Southwestern United States that encompasses parts of eastern New Mexico and northwestern Texas. One of the largest mesas or tablelands on the North American continent, the elevation rises from 3,000 feet (900 m) in the southeast to over 5,000 feet (1,500 m) in the northwest, sloping almost uniformly at about 10 feet per mile (2 m/km).
The South Plains is a region in northwest Texas, United States, consisting of 24 counties.
The Mescalero Ridge forms the western edge of the great Llano Estacado, a vast plateau or tableland in the southwestern United States in New Mexico and Texas. It is the western equivalent of the Caprock Escarpment, which defines the eastern edge of the Llano Estacado.
The Battle of Palo Duro Canyon was a military confrontation and a significant United States victory during the Red River War.

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 ," 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.
The geography of Texas is diverse and large. Occupying about 7% of the total water and land area of the U.S., it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico. Texas is in the South Central United States of America, and is considered to form part of the U.S. South and also part of the U.S. Southwest.

Blanco Canyon is a canyon located in the U.S. state of Texas.

It also gradually deepens from 50 feet (15 m) at its beginning to 300 to 500 feet at its mouth. One side canyon, 5-mile long Crawfish Canyon, was cut by Crawfish Creek as it feeds into the White River from the west.
