The Chamizal Convention was a milestone in diplomatic relations between Mexico and the United States in 1963. Chamizal National Memorial in El Paso was established to commemorate this treaty which resulted in the peaceful settlement of a century-long boundary dispute between the neighboring countries. Far more than mere acreage, Chamizal is an idea, a dynamic process, dedicated to furthering the spirit of understanding and goodwill between two nations that share one border. Utilizing the visual, literary and performing arts as a medium of interchange, Chamizal serves as an open door to help people better understand not only other cultures, but their own cultural roots as well.

Recognition of this route as an international historic trail will commemorate a shared cultural heritage and contribute in a meaningful way to eliminating cultural barriers and enriching the lives of people along El Camino Real de Tierra Adentro.

The Preserve consists of nine land units and six water corridors encompassing more than 97,000 acres. Big Thicket was the first Preserve in the National Park System established October 11, 1974, and protects an area of rich biological diversity. A convergence of ecosystems occurred here during the last Ice Age. It brought together, in one geographical location, the eastern hardwood forests, the Gulf coastal plains, and the midwest prairies.

Lyndon B. Johnson National Historical Park tells the story of our 36th President in a unique and encompassing way.

Set in the rugged beauty of the Davis Mountains of west Texas, Fort Davis is one of America's best surviving examples of an Indian Wars' frontier military post in the Southwest. From 1854 to 1891, Fort Davis was strategically located to protect emigrants, mail coaches, and freight wagons on the Trans-Pecos portion of the San Antonio-El Paso Road and the Chihuahua Trail, and to control activities on the southern stem of the Great Comanche War Trail and Mescalero Apache war trails. Fort Davis is important in understanding the presence of African Americans in the West and in the frontier military because the 24th and 25th U.S. Infantry and the 9th and 10th U.S. Cavalry, all-black regiments established after the Civil War, were stationed at the post. Today, twenty-four roofed buildings and over 100 ruins and foundations are part of Fort Davis National Historic Site. Five of the historic buildings have been refurnished to the 1880s, making it easy for visitors to envision themselves being at the fort at the height of its development.

Situated on the United States-Mexico Border, Amistad NRA is known primarily for excellent year round, water-based recreation including: boating, fishing, swimming, scuba diving and water-skiing. Amistad NRA also provides opportunities for picnicking, camping and hunting. The reservoir, at the confluence of the Rio Grande, Devils and Pecos rivers, was created by Amistad Dam in 1969.

On May 8, 1846 troops of the United States and Mexico clashed on the prairie of Palo Alto in the first battle of a two-year war. Signed into law in June 1992, Palo Alto Battlefield National Historic Site located near Brownsville preserves the 3,400-acre scene of this clash between nations and informs visitors about its national and international importance. As the only unit of the National Park Service with a primary focus on the U.S.-Mexican War, Palo Alto Battlefield also interprets the entire conflict--including the details of its origins and the broad range of consequences. In an effort to turn a scene of conflict into a place of bi-national exchange and understanding, all research and interpretation conducted by the park reflects perspectives of both the United States and Mexico.

Contrasting spectacularly with its surroundings, Lake Meredith lies on the dry and windswept High Plains of the Texas Panhandle. The lake itself was created by Sanford Dam on the Canadian River; it now fills many breaks whose walls are crowned with white limestone caprock, scenic buttes, pinnacles, and red-brown, wind-eroded coves. Lake Meredith’s shores are dotted with mesquite, prickly pear, yucca, and grasses of arid plains. Up the sheltered creek beds stand cottonwoods, soapberry, and sandbar willows. The 50,000-acre national recreation area includes a 10,000-acre reservoir where visitors can enjoy a variety of recreational opportunities for a day or an entire vacation.

Big Bend is one of the largest and least visited of America’s national parks. Over 801,000 acres await your exploration and enjoyment. From an elevation of less than 2,000 feet along the Rio Grande to nearly 8,000 feet in the Chisos Mountains, Big Bend includes massive canyons, vast desert expanses, and the entire Chisos Mountain range. Here, you can explore one of the last remaining wild corners of the United States, and experience unmatched sights, sounds, and solitude. Big Bend National Park also marks the northernmost range of many plants and animals, such as the Mexican long-nosed bat. Ranges of typically eastern and typically western species of plants and animals come together or overlap here. Here many species are at the extreme limits of their ranges. Latin American species, many from the tropics, range this far north, while northern-nesting species often travel this far south in winter. Contrasting elevations create additional, varied micro-climates that further enhance the diversity of plant and animal life and the park’s wealth of natural boundaries.

The Rio Grande Wild and Scenic River, or El Rio Bravo del Norte, provides protection and maintenance of the pristine character of the Rio Grande from the Coahuila/Chihuahua, Mexico, state border upstream from Mariscal Canyon to the Terrell/Val Verde County line in Texas downstream.

Approximately 69 miles of The Rio Grande Wild and Scenic River designation lies within Big Bend National Park, and an additional 118 miles borders the Park. The National Park Service manages both the Rio Grande Wild and Scenic River, and the Rio Grande along the park’s boundary for recreation and preservation.

For thousands of years, people came to the red bluffs above the Canadian River for flint, vital to their existence. Demand for the high quality, rainbow-hued flint is reflected in the distribution of Alibates Flint through the Great Plains and beyond.

The Monument is located 25 miles north of Amarillo and 7 miles south of Fritch.
