Mammoths, giant bison, and short-faced bears were witness to the first tremblings of the earth and firework-like explosions of molten rock thousands of feet into the air. Approximately 60,000 years ago, the rain of cooling cinders and four lava flows formed Capulin Volcano, a nearly perfectly-shaped cinder cone, rising more than 1000 feet above the surrounding landscape. Although long extinct, Capulin Volcano is dramatic evidence of the volcanic processes that shaped northeastern New Mexico. Today the pine forested volcano provide habitat for mule deer, wild turkey, and black bear. A 2-mile road spiraling to the top of the volcano and paved trails into the crater and around its rim provide access to explore the volcano and enjoy spectacular views of the surrounding volcanic landscape.

Petroglyph National Monument stretches 17 miles along Albuquerque's West Mesa, a volcanic basalt escarpment that dominates the city’s western horizon. It protects a variety of cultural and natural resources including five volcanic cones, hundreds of archeological sites and an estimated 25,000 images carved by native peoples and early Spanish settlers. Many of the images are recognizable as animals, people, brands and crosses; others are more complex.

Aztec Ruins National Monument preserves structures and artifacts of Ancestral Pueblo people from the 1100's through 1200s. People associated with Chaco Canyon to the south built and used the structures, then people related to the Mesa Verde region to the north used the site in the 1200's. The monument was established in 1923, and designated a World Heritage Site in 1987.

Santa Fe emerged as the hub of the overland continental trade network linking Mexico and United States markets—a network that included not only the Old Spanish Trail, but also the Santa Fe Trail and El Camino Real de Tierra Adentro. After the United States took control of the Southwest in 1848 other routes to California emerged, and use of the Old Spanish Trail sharply declined. Because of its rich history and national significance, the Old Spanish Trail has been designated as a national historic trail.

Established to preserve Carlsbad Cavern and numerous other caves within a Permian-age fossil reef, the park contains more than 100 known caves, including Lechuguilla Cave—the nation's deepest limestone cave at 1,567 feet (478m) and third longest. Carlsbad Cavern, with one of the world's largest underground chambers and countless formations, is highly accessible, with a variety of tours offered year-round.

Best known for mesas, sheer-walled canyons, and the ancestral Pueblo dwellings found among them, Bandelier also includes over 23,000 acres of designated Wilderness. It was named for Adolph Bandelier, a 19th-century anthropologist. Bandelier National Monument is located near Los Alamos.

Chaco Canyon was a major center of ancestral Puebloan culture between AD 850 and 1250. It was a hub of ceremony, trade, and administration for the prehistoric Four Corners area. Chaco is remarkable for its monumental public and ceremonial buildings, and its distinctive architecture. To construct the buildings, along with the associated Chacoan roads, ramps, dams, and mounds, required a great deal of well organized and skillful planning, designing, resource gathering, and construction. The Chacoan people combined pre-planned architectural designs, astronomical alignments, geometry, landscaping, and engineering to create an ancient urban center of spectacular public architecture. The Chacoan cultural sites are fragile and irreplaceable and represent a significant part of America's cultural heritage. The sites are part of the sacred homeland of Pueblo Indian peoples of New Mexico, the Hopi Indians of Arizona, and the Navajo Indians of the Southwest, all of whom continue to respect and honor them. Chaco Canyon is located in northwestern New Mexico.

El Camino Real de Tierra Adentro is recognized throughout the United States of America and Los Estados Unidos de Mexico as a timeless route of trade and cultural exchange and interaction among Spaniards and other Europeans, American Indians, Mexicans, and Americans, which shaped individual lives and communities and affected settlement and development in the greater Southwest. 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.

At the northern end of the Chihuahuan Desert lies a mountain ringed valley called the Tularosa Basin. Rising from the heart of this basin is one of the world's great natural wonders - the glistening white sands of New Mexico. Here, great wave-like dunes of gypsum sand have engulfed 275 square miles of desert and have created the world's largest gypsum dune field. The brilliant white dunes are ever changing: growing, cresting, then slumping, but always advancing. Slowly but relentlessly the sand, driven by strong southwest winds, covers everything in its path. Within the extremely harsh environment of the dune field, even plants and animals adapted to desert conditions struggle to survive. Only a few species of plants grow rapidly enough to survive burial by moving dunes, but several types of small animals have evolved a white coloration that camouflages them in the gypsum sand. White Sands National Monument preserves a major portion of this gypsum dune field, along with the plants and animals that have successfully adapted to this constantly changing environment.

El Malpais National Monument and Conservation Area near Grants, New Mexico, preserves 114,277 acres of which 109,260 acres are federal and 5,017 acres are private. El Malpais means "the badlands" but contrary to its name this unique area holds many surprises, many of which researchers are now unraveling. Volcanic features such as lava flows, cinder cones, pressure ridges and complex lava tube systems dominate the landscape. Sandstone bluffs and mesas border the eastern side, providing access to vast wilderness. For more than 10,000 years people have interacted with the El Malpais landscape. Historic and archeological sites provide reminders of past times. More than mere artifacts, these cultural resources are kept alive by the spiritual and physical presence of contemporary Indian groups, including the Puebloan peoples of Acoma, Laguna,and Zuni, and the Ramah Navajo. These tribes continue their ancestral uses of El Malpais including gathering herbs and medicines, paying respect, and renewing ties.

Pecos preserves 12,000 years of history including the ancient pueblo of Pecos, two Spanish Colonial Missions, Santa Fe Trail sites, 20th century ranch history of Forked Lightning Ranch, and the site of the Civil War Battle of Glorieta Pass.

Fort Union was established in 1851 by Lieutenant Colonel Edwin V. Sumner as a guardian and protector of the Santa Fe Trail. During its forty-year history, three different forts were constructed close together. The third and final Fort Union was the largest in the American Southwest, and functioned as a military garrison, territorial arsenal, and military supply depot for the southwest. Today, visitors use a self-guided tour path to visit the second fort and the large, impressive ruins of the third Fort Union. The largest visible network of Santa Fe Trail ruts can be seen here. Fort Union is located near Watrous.

Gila Cliff Dwellings National Monument offers a glimpse of the homes and lives of the people of the Mogollon culture who lived in the Gila Wilderness from the 1280s through the early 1300s. The surroundings probably look today very much like they did when the cliff dwellings were inhabited. It is surrounded by the Gila National Forest and lies at the edge of the Gila Wilderness, the nation's first designated wilderness area. This designation means that the wilderness character of the area will not be altered by the intrusion of roads or other evidence of human presence. Located 44 miles outside of Silver City.

Once, thriving American Indian trade communities of Tiwa and Tompiro speaking Puebloans inhabited this remote frontier area of central New Mexico. Early in the 17th-century Spanish Franciscans found the area ripe for their missionary efforts. However, by the late 1670s the entire Salinas District, as the Spanish had named it, was depopulated of both Indian and Spaniard. What remains today are austere yet beautiful reminders of this earliest contact between Pueblo Indians and Spanish Colonials: the ruins of four mission churches, at Quarai, Abó, and Gran Quivira and the partially excavated pueblo of Las Humanas or, as it is known today, Gran Quivira. Established in 1980 through the combination of two New Mexico State Monuments and the former Gran Quivira National Monument, the present Monument comprises a total of 1,100 acres.

Between 1821 and 1880, the Santa Fe Trail was primarily a commercial highway connecting Missouri and Santa Fe, New Mexico. From 1821 until 1846, it was an international commercial highway used by Mexican and American traders. In 1846, the Mexican-American War began. The Army of the West followed the Santa Fe Trail to invade New Mexico. When the Treaty of Guadalupe ended the war in 1848, the Santa Fe Trail became a national road connecting the United States to the new southwest territories. Commercial freighting along the trail continued, including considerable military freight hauling to supply the southwestern forts. The trail was also used by stagecoach lines, thousands of gold seekers heading to the California and Colorado gold fields, adventurers, fur trappers, and emigrants. In 1880 the railroad reached Santa Fe and the trail faded into history.
