Alibates Flint Quarries National Monument is a U.S. national monument in the state of Texas. 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. Indians of the Ice Age Clovis culture used Alibates flint for spear points to hunt the imperial mammoth before the Great Lakes were formed. The flint usually lies just below the surface at ridge level in a layer up to 6 ft thick. The quarry pits were not very large, between 5 and 25 ft wide and 4 to 7 ft deep. Many of these quarries were exploited by the Antelope Creek people of the Panhandle culture between 1200 and 1450 AD. The stone-slabbed, multiroom houses built by the Antelope Creek people have long been of interest to the public and studied by archaeologists. Today, this area is protected by the U.S. National Park Service and can only be viewed by ranger-led guided tours, which must be reserved in advance.

Big Bend National Park is an American national park located in West Texas, bordering Mexico. The park has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States, and was named after a large bend in the Rio Grande/Río Bravo. The park protects more than 1,200 species of plants, more than 450 species of birds, 56 species of reptiles, and 75 species of mammals. Additional park activities include scenic drives, programs led by Big Bend park rangers, and stargazing.
The Burro Mesa Archeological District encompasses a quarry in Big Bend National Park used by Native Americans as a source of chert for chipped-stone tools. The quarry was used intermittently beginning in the paleoindian period starting about 12,000 to 13,000 years ago. The chert is found in a variety of colors and rests on top of tuff beds which themselves contain veins of kaolinite that was suitable for making claystone ornaments and beads. The quarry area is carpeted with lithic debris from the initial knapping process by which chert was rough-shaped into material of suitable size and shape for later refinement at more convenient locations.
Buttermilk Creek Complex refers to the remains of a paleolithic settlement along the shores of Buttermilk Creek in present-day Salado, Texas dated to approximately 15,500 years old. If confirmed, the site represents evidence of human settlement in the Americas that pre-dates the Clovis culture.

Caddo Mounds State Historic Site (41CE19) is an archaeological site in Weeping Mary, Texas. This Caddoan Mississippian culture site is composed of a village and ceremonial center that features two earthwork platform mounds and one burial mound. Located on an ancient Native American trail later named by the Spanish as El Camino Real de los Tejas, the settlement developed hundreds of years before the arrival of Europeans and Africans to the region. Archaeologists believe the site was created in approximately 800 CE, with most major construction taking place between 1100 and 1300 CE.

El Orcoquisac Archeological District is a registered U.S. historic site located near Galveston Bay in present-day Wallisville, Texas. The site preserves an important Spanish presidio and trading center as well as an important settlement for the Akokisa and Bidai tribes that once inhabited the area.
The French colonization of Texas began with the establishment of a fort in present-day southeastern Texas. It was established in 1685 near Arenosa Creek and Matagorda Bay by explorer Robert Cavelier de La Salle. He intended to found the colony at the mouth of the Mississippi River, but inaccurate maps and navigational errors caused his ships to anchor instead 400 miles (640 km) to the west, off the coast of Texas. The colony survived until 1688. The present-day town of Inez is near the fort's site. The colony faced numerous difficulties during its brief existence, including Native American raids, epidemics, and harsh conditions. From that base, La Salle led several expeditions to find the Mississippi River. These did not succeed, but La Salle did explore much of the Rio Grande and parts of east Texas.

The Gault archaeological site is an extensive, multicomponent site located in central Texas, United States, about 40 miles (64 km) north of Austin. It bears evidence of almost continuous human occupation, starting at least 16,000 years ago—making it one of the few archaeological sites in the Americas at which compelling evidence has been found for human occupation dating to before the appearance of the Clovis culture.

Guadalupe Mountains National Park is an American national park in the Guadalupe Mountains, east of El Paso, Texas. The mountain range includes Guadalupe Peak, the highest point in Texas at 8,749 feet (2,667 m), and El Capitan used as a landmark by travelers on the route later followed by the Butterfield Overland Mail stagecoach line. The ruins of a stagecoach station stand near the Pine Springs visitor center. The restored Frijole Ranch contains a small museum of local history and is the trailhead for Smith Spring. The park covers 86,367 acres in the same mountain range as Carlsbad Caverns National Park, about 25 miles (40 km) to the north in New Mexico. The Guadalupe Peak Trail winds through pinyon pine and Douglas-fir forests as it ascends over 3,000 feet (910 m) to the summit of Guadalupe Peak, with views of El Capitan and the Chihuahuan Desert.

La Belle was one of Robert de La Salle's four ships when he explored the Gulf of Mexico with the ill-fated mission of starting a French colony at the mouth of the Mississippi River in 1685. La Belle was wrecked in present-day Matagorda Bay the following year, dooming La Salle's Texas colony to failure. The wreckage of La Belle lay forgotten until it was discovered by a team of state archaeologists in 1995. The discovery of La Salle's flagship was regarded as one of the most important archaeological finds of the century in Texas, and a major excavation was launched by the state of Texas that, over a period of about a year, recovered the entire shipwreck and over a million artifacts.

Operated by the Texas Historical Commission, the site includes a campground, museum, gift shop and hiking trails.
Mission San José y San Miguel de Aguayo is an historic Catholic mission in San Antonio, Texas, United States. The mission was named in part for the Marquis de San Miguel de Aguayo, José de Azlor y Virto de Vera. Many buildings on the campus of Texas Tech University in Lubbock, Texas, borrow architectural elements from those found at Mission San José.

Mission San Juan Capistrano was founded in 1731 by Spanish Catholics of the Franciscan Order, on the eastern banks of the San Antonio River in present-day San Antonio, Texas. The new settlement was named for a 15th-century theologian and warrior priest who resided in the Abruzzo region of Italy. The mission San Juan was named after Saint John of Capestrano.

Mission Santa Cruz de San Sabá was one of the Spanish missions in Texas. It was established in April 1757, along with the Presidio San Luis de las Amarillas, later renamed Presidio of San Sabá, in what is now Menard County. Located along the San Saba River, the mission was intended to convert members of the Lipan Apache tribe. Although no Apache ever resided at the mission, its existence convinced the Comanche that the Spanish had allied with the Comanche's mortal enemy. In 1758 the mission was destroyed by 2,000 warriors from the Comanche, Tonkawa, Yojuane, Bidai and Hasinai tribes. It was the only mission in Texas to be completely destroyed by Native Americans. The Indians did not attack the nearby presidio.

Panhandle culture is a prehistoric culture of the southern High Plains during the Middle Ceramic Period from AD 1200 to 1400. Panhandle sites are primarily in the panhandle and west central Oklahoma and the northern half of the Texas Panhandle.
San Antonio Missions National Historical Park is a National Historical Park and part of a UNESCO World Heritage Site preserving four of the five Spanish frontier missions in San Antonio, Texas, USA. These outposts were established by Catholic religious orders to spread Christianity among the local natives. These missions formed part of a colonization system that stretched across the Spanish Southwest in the 17th, 18th, and 19th centuries.

The Southern Plains villagers were semi-sedentary American Indians who lived on the Great Plains in western Oklahoma, Texas, Kansas, and southeastern Colorado from about AD 800 until AD 1500.

The Spanish Missions in Texas comprise a series of religious outposts established by Spanish Catholic Dominicans, Jesuits, and Franciscans to spread the Catholic doctrine among area Native Americans, but with the added benefit of giving Spain a toehold in the frontier land. The missions introduced European livestock, fruits, vegetables, and industry into the Texas area. In addition to the presidio and pueblo (town), the misión was one of the three major agencies employed by the Spanish crown to extend its borders and consolidate its colonial territories. In all, twenty-six missions were maintained for different lengths of time within the future boundaries of the state of Texas.

The Waco Mammoth National Monument is a paleontological site and museum in Waco, Texas, United States where fossils of 24 Columbian mammoths and other mammals from the Pleistocene Epoch have been uncovered. The site is the largest known concentration of mammoths dying from a (possibly) reoccurring event, which is believed to have been a flash flood. The mammoths on site did not all die at the same time but rather during three separate events in the same area. A local partnership developed around the site after the initial bone was discovered. The Waco Mammoth Foundation worked in partnership with the city of Waco and Baylor University to develop the site. Baylor's involvement mainly included the research, preservation, and storage of materials from the site, while the city of Waco contributed to the protection of the land. In 2015, they successfully sought the National Monument designation to bring the expertise of the National Park Service into the partnership.
