The Llano Estacado is a large plateau located in the southwestern United States, primarily in the states of Texas and New Mexico. It covers an area of approximately 37,000 square miles and is characterized by its flat terrain and high elevation, averaging around 3,000 feet above sea level. The region is known for its unique geography, which includes mesas and canyons. This plateau is part of the larger Great Plains and is one of the largest mesas in North America. The Llano Estacado is also significant for its agriculture, particularly in cotton and cattle ranching, due to its fertile soil and favorable climate. The area has a rich cultural history, influenced by Native American tribes and later by European settlers.
