Tucumcari Mountain is a mesa outside of Tucumcari, New Mexico.

A mesa (Spanish and Portuguese for "table") is the American English term for tableland, an elevated area of land with a flat top and sides that are usually steep cliffs. It takes its name from its characteristic table-top shape.

It is a characteristic landform of arid environments, particularly the Southwestern United States. Many examples are also found in Spain, Sardinia, North and South Africa, Arabia, India, Australia, badlands and in the mountainous parts of Wyoming, Idaho, Montana, Texas, and Oklahoma. Grand Mesa is a large mesa located in western Colorado in the Southwest United States.

The term "mesa" is used throughout the United States to describe a flat-topped mountain or hill. In Spanish such a landform is more usually known as a meseta.^[1]

Formation[link]

Mesas are formed by weathering and erosion of horizontally layered rocks that have been uplifted by tectonic activity. Variations in the ability of different types of rock to resist weathering and erosion cause the weaker types of rocks to be eroded away, leaving the more resistant types of rocks topographically higher than their surroundings.^[2] This process is called differential erosion. The most resistant rock types include sandstone, conglomerate, quartzite, basalt, chert, limestone, lava flows and sills.^[2] Lava flows and sills, in particular, are very resistant to weathering and erosion, and often form the flat top, or caprock, of a mesa. The less resistant rock layers are mainly made up of shale, a softer rock that weathers and erodes more easily.^[2]

The differences in strength of various rock layers is what gives mesas their distinctive shape. Less resistant rocks are eroded away on the surface into valleys, where they collect water drainage from the surrounding area, while the more resistant layers are left standing out.^[2] A large area of very resistant rock, such as a sill may shield the layers below it from erosion while the softer rock surrounding it is eroded into valleys, thus forming a caprock.

Differences in rock type also reflect on the sides of a mesa, as instead of smooth slopes, the sides are broken into a staircase pattern called "cliff-and-bench topography".^[2] The more resistant layers form the cliffs, or stair steps, while the less resistant layers form gentle slopes, or benches, between the cliffs. Cliffs retreat and are eventually cut off from the main cliff, or plateau, by basal sapping. When the cliff edge does not retreat uniformly, but instead is indented by headward eroding streams, a section can be cut off from the main cliff, forming a mesa.^[2]

Basal sapping occurs as water flowing around the rock layers of the mesa erodes the underlying soft shale layers, either as surface runoff from the mesa top or from groundwater moving through permeable overlying layers, which leads to slumping and flowage of the shale.^[3] As the underlying shale erodes away, it can no longer support the overlying cliff layers, which collapse and retreat. When the caprock has caved away to the point where only a little remains, it is known as a butte.

Mesas on Mars[link]

There is a transitional zone on Mars known as the fretted terrain which lies between highly cratered highlands and less cratered lowlands. The younger lowland exhibits steep walled mesas and knobs. The mesa and knobs are separated by flat lying lowlands. They are thought to be formed from ice-facilitated mass wasting processes from ground or atmospheric sources. The mesas and knobs decrease in size with increasing distance from the highland escarpment. The relief of the mesas range from nearly 2 km to 100m depending on the distance they are from the escarpment.^[4]

Biography[link]

The Grid formed in 1988 and had their first success with debut single, "Floatation", released on East West Records in 1990. They went on to release a string of ten UK hit singles and four albums,^[1] and toured the UK, Europe, Asia and Australia. The group's 1994 album Evolver reached #14 in the UK Albums Chart.^[1] The lead single from this album, "Swamp Thing", featuring elaborate banjo lines played by Roger Dinsdale. "Swamp Thing" proved to be a commercial success in the UK, Europe and Australia, reaching #3 in the UK^[1] and Australia and selling a total of one million copies.^{[citation needed]}

In 1996, Norris and Ball agreed to a hiatus period in order pursue individual music interests. Norris formed the Droyds, which went on to remix tracks by musicians including Armand Van Helden and Siobhan Fahey, and wrote the official biography of Paul Oakenfold (published in 2007): Ball reformed Soft Cell with Marc Almond, and also wrote music scores for films.^{[citation needed]} Norris has since formed the psychedelic duo, Beyond The Wizard's Sleeve, with DJ Erol Alkan, and has released a number of solo records and remixes under the name The Time and Space Machine.

The duo reunited in 2005, initially playing two gigs under the name GDM with female singer Misty Woods, before writing and recording new material as the Grid. A single, "Put Your Hands Together", was released in 2007 and an album, Doppelgänger, followed in 2008. Both were released on the Some Bizzare label. The album featured vocals by the British musician, Chris Braide.

Mesa Verde National Park is a U.S. National Park and UNESCO World Heritage Site located in Montezuma County, Colorado, United States. The park was created in 1906 by President Theodore Roosevelt, to protect some of the best-preserved cliff dwellings in the world, or as he said, "preserve the works of man". It occupies 81.4 square miles (211 km²) near the Four Corners and features numerous ruins of homes and villages built by the Ancestral Puebloan people, sometimes called the Anasazi. There are over 4,000 archaeological sites and over 600 cliff dwellings of the Pueblo people at the site.

The Anasazi inhabited Mesa Verde between AD 600 to 1300, though there is evidence they left before the turn of the century. They were mainly subsistence farmers, growing crops on nearby mesas. Their primary crop was corn, the major part of their diet. Men were also hunters, which further increased their food supply. The women of the Anasazi are famous for their elegant basket weaving. Anasazi pottery is as famous as their baskets; their artifacts are highly prized. The Anasazi kept no written records.

By 750 AD, the people were building mesa-top villages made of adobe. In the late 1190's CE, they began to build the cliff dwellings for which Mesa Verde is famous.

Mesa Verde is best known for cliff dwellings, which are structures built within caves and under outcropping in cliffs — including Cliff Palace, thought to be the largest cliff dwelling in North America. The Spanish term Mesa Verde translates into English as "green table". It is considered to contain some of the most notable and best preserved archaeological sites.^[3]

Geography and climate[link]

Mesa Verde National Park, with 52,000 acres, is located in the southwestern Colorado.^[4][5]:220 Its canyons were created by erosion from receding ancient oceans and waterways, which resulted in Mesa Verde National Park elevations ranging from about 6,000 to 8,572 feet (1,800 to 2,613 m), the highest elevation at Park Point. The terrain in the park is now a transition zone between the low desert plateaus and the Rocky Mountains.^{[6]:9-13, 24}

The climate is semi-arid. Water for farming and consumption by the Ancient Pueblo Peoples was provided by summer rains, winter snowfall and seeps and springs in and near the Mesa Verde villages. The middle mesa areas, 10 degrees cooler than on the mesa at 7,000 feet (2,100 m), were ideal for agriculture, and the lower temperatures reduced the amount of water needed for agriculture.^[6]:15 The cliff dwellings were built with obvious attention to managing solar energy. In the winter, the angle of the sun warmed the masonry of the cliff dwellings, warm breezes blew from the valley, and the air was 10-20 degrees warmer in the canyon alcoves than on the top of the mesa. In the summer, due to the angle of the sun, much of the village was protected from direct sunlight in the cliff dwellings.^[6]:16-17

By 1300 CE prolonged drought had caused the fragile adaptation to collapse and the Mesa Verde area was abandoned. The surviving Mesa Verde people retreated to the south and east.

Geologic history[link]

In the late Cretaceous Period, the Mancos Shale was deposited on top of the Dakota Sandstone, which is the rock formation that can be found under much of Colorado. The beds of the Mancos Shale are "fine-grained sand-stones, mudstones, and shales" which accumulated in the deep water of the Cretaceous Sea. It has a high clay content which causes it to expand when wet leading to sliding of the terrain.^[7]

On top of this shale, there are three formations in the Mesaverde group which reflect the changes in depositional environment in the area over time. The first is the Point Lookout Sandstone, which is named for the Point Lookout feature in the park (elevation 8427 feet).^[7] This sandstone--which formed in the marine environment of shallow water when the Cretaceous sea was receding--is "massive, fine-grained, cross-bedded, and very resistant", in its layers reflecting waves and currents that were present during the time of its formation. Its sediments are approximately 400 feet thick, and its upper layers feature fossiliferous invertebrates.^[7]

Next is the Menefee Formation, the middle formation whose content features "interbedded carbonaceous shales, siltstones, and sandstones". These were deposited in a semi-marine environments of brackish water in "bays, lagoons, and swamps". Due to its depositional environment and the organic material in its composition, there are thin coal seams running through the Menefee Formation. At the top, this Formation is intruded upon or "inter fingers with" the Cliff House Sandstone.^[7]

The Cliff House Sandstone is the "youngest rock layer present in the area." It was formed after the Cretaceous sea had completely receded and as a result has a high sand content from beaches, dunes, etc. and from this receives its characteristic yellow tint to its canyon faces. Like the Point Lookout Sandstone, it is about 400 feet thick. It contains numerous fossil beds of different types of shells, fish teeth, and other invertebrate leftovers from the receded sea. The shale zones in this feature determine where alcoves formed where the Anasazi indians constructed their dwellings.^[7]

Continuing through the Cretaceous period and into the early Tertiary, there was uplifting in the area of the Colorado Plateaus, the San Juan Mountain, and the La Plata Mountain which led to the formation of the Mesa Verde pediment with the help of erosion. Small channels of water ran across this formation depositing gravel. Later in the tertiary, the last period of uplift and rock tilting towards the south caused these streams to cut rapidly into the rock removing loose sediment and forming the vast canyons seen today. This caused the isolation of the Mesa Verde pediment from surrounding rock. Today, since the climate is more arid, these erosional processes are significantly slowed.^[7]

History[link]

Mesa Verde residents[link]

The Mesa Verde area was settled by 400 CE, and villages subsequently spread into a variety of local ecological settings (reference 34). Over time masonry replaced jacal walls and central villages came to dominate smaller subordinate ones scattered around them in multivillage polities.

Modified Basketmakers AD 550 to 750

This era resulted in the introduction of pottery, which reduced the number of baskets that they made and eliminated the creation of woven bags. The simple, gray pottery allowed them a better tool for cooking and storage. Beans were added to the cultivated diet. They replaced spears and atlatls with bows and arrows which made hunting easier, and thus the acquisition of hides for clothing. ^[8] Turkey feathers were woven into blankets and robes. On the rim of Mesa Verde, small groups built pit houses several feet below the surface with elements suggestive of the introduction of celebration rituals.^[6]:33-37

Developmental Pueblo AD 750 to 1100

Pueblo buildings were built with stone, windows facing south, and in U, E and L shapes. The buildings were located more closely together and reflected deepening religious celebration. Towers were built near kivas and likely used for lookouts. Pottery became more versatile, including pitchers, ladles, bowls, jars and dishware for food and drink. White pottery with black designs emerged, the pigments coming from plants. Water management and conservation techniques, including the use of reservoirs and silt-retaining dams also emerged during this period.^[6]:39-45

Like the people at Hovenweep National Monument and Canyon de Chelly National Monument, about AD 1100, the Mesa Verde village communities moved from mesa tops to the heads of canyons.^[9]:146

Great Pueblo period AD 1100 to 1300

Architecture

Since Fire Temple was at least partially built to conform to the dimensions of the cliff alcove in which it was built, it is neither round in form nor truly subterranean like other structures generally defined as kivas.

Mesa Verde is best known for a large number of well-preserved cliff dwellings, houses built in shallow caves and under rock overhangs along the canyon walls. The structures contained within these alcoves were mostly blocks of hard sandstone, held together and plastered with adobe mortar. Specific constructions had many similarities but were generally unique in form due to the individual topography of different alcoves along the canyon walls. In marked contrast to earlier constructions and villages on top of the mesas, the cliff dwellings of Mesa Verde reflected a region-wide trend towards the aggregation of growing regional populations into close, highly defensible quarters during the AD 1200s.^{[6]:13, 47-59}

While much of the construction in these sites conforms to common Pueblo architectural forms, including kivas, towers, and pit-houses, the space constrictions of these alcoves necessitated what seems to have been a far denser concentration of their populations. Mug House, a typical cliff dwelling of the period, was home to around 100 people who shared 94 small rooms and eight kivas built against each other and sharing many of their walls; builders in these areas maximized space in any way they could, with no areas considered off-limits to construction.^[10]

Not all of the people in the region lived in cliff dwellings; many colonized the canyon rims and slopes in multi-family structures that grew to unprecedented size as populations swelled.^[10] Decorative motifs for these sandstone/mortar constructions, both surface and cliff dwellings, included T-shaped windows and doors. This has been taken by some archaeologists, such as Stephen H. Lekson, as evidence of the continuing reach of the Chaco Canyon elite system, which had seemingly collapsed around a century before.^[11] Other researchers see these motifs as part of a more generalized Puebloan style and/or spiritual significance, rather than evidence of a continuing specific elite socioeconomic system.^[12]

The buildings that were built here showed a trend at the time of inhabitants moving towards time masonry techniques over former jacal walls that were commonplace in architectural design. One of the reasons settlers moved into the cliff dwellings was to increase their farming production by creating irrigation systems as water flowed down the cliff to attempt to combat the changing, drought induced, climate.

Migration from Mesa Verde

These construction and water-related activities lead archaeologists to speculate that climatic change and increased population placed the communities under stress. The ancient people of Mesa Verde left the area in the late 1200s, possibly in response to a 24-year regional drought.^{[6]:73-74[13]:133-137[nb 1]} People in the entire Four Corners region were also abandoning smaller communities at that time, and the area may have been nearly empty by AD 1300.^{[5]:220[13]:156} Having left the Mesa Verde area, the people of Mesa Verde moved south to southern Arizona and New Mexico.^[6]:74

Since then, there is evidence of Native Americans hunting in the Mesa Verde area. There is no evidence, though, that anyone lived in the cliff dwellings or pueblos after the Ancient Puebloan people.^[13]:9

Notable sites[link]

Pueblo	Photo	Comments
Balcony House		Set on a high ledge facing east, Balcony House with 45 rooms and 2 kivas, would have been cold for its residents in the winter. The modern visitor enters by climbing a 32-foot ladder and a crawling through a 12-foot tunnel. The exit, a series of toe-holds in a cleft of the cliff, was believed to be the only entry and exit route for the cliff dwellers, which made the small village easy to defend and secure. One log was dated at AD 1278 so it was likely built not long before the Mesa Verde people migrated out of the area.[5]:225-226[6]:55-56 It was officially excavated by Jesse Nusbaum, one of the first Superintendents of Mesa Verde National Park, in 1910.[14] Visitors can enter Balcony House through ranger-guided tours.[15] This photo is of Emmett Harryson, a Navajo, at a T-shaped doorway at Balcony House (1929).
Cliff Palace		This multi-storied ruin, the largest and best-known of the cliff dwellings in Mesa Verde, is located in the largest cave in the center of the Great Mesa. It was south- and southwest-facing, providing greater warmth from the sun in the winter. The site had 200 rooms, including storage rooms, open courts, walkways, and 23 kivas. Dating back more than 700 years, the dwelling is constructed of sandstone, wooden beams, and mortar.[16] Many of the rooms were brightly painted.[6]:51[13]:3, 29, 31, 37
Long House		Located on the Wetherill Mesa, Long House is the second-largest village, for about 150 people. The location was excavated as part of the Wetherhill Mesa Archaeological Project during the years 1959 through 1961.[17] The 150 rooms are not clustered like the standard cliff dwellings, and they are not one of the most elegant set of buildings. Stones were used without shaping for fit and stability. Two overhead ledges contain more rooms. One ledge seems to include an overlook with small holes in the wall to see the rest of the village below. A spring is accessible within several hundred feet and seeps are located in the rear of the village.[6]:57Long Houses were structures designed to expand as needed to hold large extended families. [18]
Mesa Verde Reservoirs		These ancient reservoirs, built by the Ancient Puebloans,[6]:43 on September 26, 2004, became a National Civil Engineering Historic Landmark.[19]
Mug House		This ruin situated on Wetherill Mesa contains 94 rooms, a large kiva, and a nearby reservoir. It received its name from four mugs the Charles Mason and the Wetherill brothers found strung together on a string.[6]:59 This ceremonial structure has a keyhole shape, due to a recess behind the fireplace and a deflector, that is considered an element of the Mesa Verde style. The rooms clustered around the kiva formed part of the courtyard, indicating the kiva would have been roofed.[citation needed]
Oak Tree House		Oak Tree House and neighboring Fire Temple can be visited via a 2 hour ranger-guided hike.[20]
Spruce Tree House		Spruce Tree House is the third-largest village, within several hundred feet of a spring, and had 130 rooms and eight kivas. It was constructed sometime between AD 1211 and 1278. It is believed anywhere from 60 to 80 people lived there at one time.[21] Because of its protective location, it is well preserved.[6]:52[21] The short trail to Spruce House begins at the Chapin Mesa Archeological Museum.[22]
Square Tower House		The Square Tower House is one of the stops on the Mesa Top Loop Road driving tour.[22] The tower that gives this site its name is the tallest structure in Mesa Verde. This cliff dwelling was occupied between AD 1200 and 1300.[citation needed]

Approximately 600 of the over 4700 archeological sites found in Mesa Verde National Park are cliff dwellings.^[6]:7 In addition to the cliff dwellings, Mesa Verde boasts a number of mesa-top ruins.^[5]:220-221 Examples open to public access include the Far View Complex and Cedar Tree Tower on Chapin Mesa, and Badger House Community, on Wetherill Mesa.^[5]:222

Discovery[link]

Ute[link]

The area in and around Mesa Verde had been home to the Utes. In 1868, a treaty between the United States government and the Ute tribe recognized Ute ownership of Colorado land by identifying land west of the Continental Divide as Ute land. After there had become an interest in land in western Colorado, a new treaty in 1873 left the Ute with a strip of land in southwestern Colorado between the border with New Mexico and 15 miles north. Most of Mesa Verde lies within this strip of land. The Ute wintered in the warm, deep canyons and found sanctuary there and the high plateaus of Mesa Verde. Believing the cliff dwellings to be sacred ancestral sites, they did not live in the ancient dwellings.^[6]:77

Spanish explorers[link]

Mexican-Spanish missionaries and explorers Francisco Atanasio Domínguez and Silvestre Vélez de Escalante, seeking a route from Santa Fe to California, faithfully recorded their travels in 1776. They reached the Mesa Verde (green plateau) region, which they named after its high, tree-covered plateaus, but they never got close enough, or into the needed angle, to see the ancient stone villages.^{[6]:77[13]:9-10} They were the first white men to travel the route through much of the Colorado Plateau into Utah and back through Arizona to New Mexico.^[23]

1870s and 1880s American visitors[link]

• Occasional trappers and prospectors visited, with one prospector, John Moss, making his observations known in 1873.^[24]
• The following year, he led eminent photographer William Henry Jackson through Mancos Canyon, at the base of Mesa Verde. There, Jackson both photographed and publicized a typical stone cliff dwelling.^[24]
• In 1875, geologist William H. Holmes retraced Jackson's route.^[24]
• Reports by both Jackson and Holmes were included in the 1876 report of the Hayden Survey, one of the four federally financed efforts to explore the American West. These and other publications led to proposals to study Southwestern archaeological sites systematically.^[24]
• Virginia McClurg, a journalist for the New York Daily Graphic, visited Mesa Verde in 1882 and 1885 in her quest to find Ancient Pueblo settlements. In 1885, her party found Echo Cliff House, Three Tier House and Balcony House, and these findings induced her future work to protect the dwellings and artifacts.^{[6]:78[25]:61-72}
• A family of cattle ranchers, the Wetherills, befriended members of the Ute tribe near their ranch southwest of Mancos, Colorado. With the Ute tribe's approval, the Wetherills were allowed to bring cattle into the lower, warmer plateaus of the present Ute Mountain Ute Tribe in the winter. Word had spread of the dwellings of Ancient Pueblo people. Acowitz, a member of the Ute tribe, told the Wetherills of a special dwelling in Mesa Verde: "Deep in that canyon and near its head are many houses of the old people - the Ancient Ones. One of those houses, high, high in the rocks, is bigger than all the others. Utes never go there, it is a sacred place."^{[6]:79[13]:17-18} On December 18, 1888, Richard Wetherill and Charlie Mason, cowboys from Mancos, found Cliff Palace in Mesa Verde after spotting the ruins from the top of the mesa. Wetherill gave the ruin its present-day name. Richard Wetherill, family and friends explored the ruins and gathered artifacts, some of which they sold to the Historical Society of Colorado and much of which they kept.^{[6]:79-80[13]:17-24}
• Among the people who stayed with the Wetherills and explored the cliff dwellings was mountaineer, photographer, and author Frederick H. Chapin, who visited the region during 1889 and 1890. He described the landscape and ruins in an 1890 article and later in an 1892 book, The Land of the Cliff-Dwellers, which he illustrated with hand-drawn maps and personal photographs.^[25]:63

Gustaf Nordenskiöld[link]

The Wetherills also hosted Gustaf Nordenskiöld, the son of polar explorer Adolf Erik Nordenskiöld, in 1891.^{[6]:81[13]:27} Nordenskiöld was a trained mineralogist who introduced scientific methods to artifact collection, recorded locations, photographed extensively, diagrammed sites, and correlated what he observed with existing archaeological literature as well as the home-grown expertise of the Wetherills.^[4] He removed a lot of artifacts and sent them to Sweden, where they eventually went to the National Museum of Finland. Nordenskiöld published, in 1893, The Cliff Dwellers of the Mesa Verde.^[6]:82-84 When Nordenskiöld shipped the collection that he made of Mesa Verde artifacts, the event initiated concerns about the need to protect Mesa Verde land and its resources.^[6]:83-84

National Park[link]

Becoming a National Park[link]

Virginia McClurg was diligent in her efforts between 1887 and 1906 to inform the United States and European community of the importance of protecting the important historical material and dwellings in Mesa Verde. Her efforts included enlisting support from 250,000 women through the Federation of Women's Clubs, writing and having published poems in popular magazines, giving speeches domestically and internationally, and forming the Colorado Cliff Dwellers Association. The Colorado Cliff Dwellers' purpose was to protect the resources of Colorado cliff dwellings, reclaiming as much of the original artifacts as possible and sharing information about the people who dwelt there. A fellow activist for protection of Mesa Verde and prehistoric archaeological sites included Lucy Peabody, who, located in Washington, D.C., met with members of Congress to further the cause.^{[4][6]:85[25]:61-72}

Former Mesa Verde National Park superintendent Robert Heyder communicated his belief that the park might have been far more significant with the hundreds of artifacts taken by Nordenskiöld.^[26]

J. Walter Fewkes at Mesa Verde cliff dwellings, circa 1910.

By the end of the 19th century, it was clear that Mesa Verde needed protection from people in general who came to Mesa Verde and created or sold their own collection of artifacts. In a report to the Secretary of the Interior, Smithsonian Institute Ethnologist J. Walter Fewkes described vandalism at Mesa Verde's Cliff Palace:

Parties of "curio seekers" camped on the ruin for several winters, and it is reported that many hundred specimens there have been carried down the mesa and sold to private individuals. Some of these objects are now in museums, but many are forever lost to science. In order to secure this valuable archaeological material, walls were broken down [...] often simply to let light into the darker rooms; floors were invariably opened and buried kivas mutilated. To facilitate this work and get rid of the dust, great openings were broken through the five walls which form the front of the ruin. Beams were used for firewood to so great an extent that not a single roof now remains. This work of destruction, added to that resulting from erosion due to rain, left Cliff Palace in a sad condition.^[27]

Milestones[link]

Some key occurrences are:

• 1756 - Don Juan Maria de Rivera, under orders from New Mexico governor Tomas Velez Cachupin, led what was possibly the first expedition of white men northwest from New Mexico. Rivera’s men saw ancient "ruins," but made no identifiable reference to Mesa Verde in their journals.
• 1886 - A Denver Tribune Republican article printed on December 12, 1886, was the first known suggestion to create a National Park around the archaeological site, meaning it took us 20 years to finally bring that suggestion to fruition.
• 1906 - President Teddy Roosevelt approved creation of the Mesa Verde National Park and the Federal Antiquities Act of 1906.^[6]:84-85 The park was an effort to "preserve the works of man" and was the first of its kind. The park was named with the Spanish term for green table because of its forests of juniper and piñon trees.^[28]
• 1908-1922 - The Spruce Tree House, Cliff Palace and Sun Temple ruins were stabilized.^[5]:221 Most of the early efforts were led by J. Walter Fewkes.^[29]
• 1930s-1940s - Civilian Conservation Corps workers, starting in 1932, played key roles in excavation efforts, building trails and roads, creating museum exhibits and constructing buildings at Mesa Verde.^[29]
• 1958-1965 - Wetherill Mesa Archeological Project included archaeological excavations, stabilization of sites, and surveys. With excavation and study of eleven Wetherill Mesa sites, it is considered the largest archaeological effort in the United States.^[29]
• 1966 - As with all historical areas administered by the National Park Service, the park was listed on the National Register of Historic Places.^[30]
• 1978 - It was designated a World Heritage Site in 1978.^[29]
• 1987 - The Mesa Verde Administrative District was listed on the National Register of Historic Places.^[30]
• 1996, 2000 (twice), 2001, 2002, and 2003 - The park, which is covered with pinyon pine and Utah juniper forests, suffered from a large number of wildland fires.^[31]

Mesa Verde's park entrance is on U.S. Route 160, about 9 miles (14 km) east of the community of Cortez and about 7 miles (11 km) west of Mancos, Colorado.^[32]

The park protects over 4,000 archaeological sites, including 600 separate cliff dwellings.^{[citation needed]}

Of the park's 600 separate cliff dwellings, 230 of them have been assessed for damage, and may be repaired in the coming years.

The Far View visitor center is 15 miles (24 km) from the entrance, and Chapin Mesa (the most popular area) is another 6 miles (9.7 km) beyond the visitor center.^[32]

Park facilities and access:^[32]

• The park's Chapin Mesa Archeological Museum is open all year.
• Three of the cliff dwellings on Chapin Mesa are open to the public.
  • Spruce Tree House is open all year, weather permitting.
  • Balcony House, Long House and Cliff Palace require tour tickets for ranger-guided tours. Many other dwellings are visible from the road but not open to tourists.
• The park offers hiking trails, a campground, and, during peak season, facilities for food, fuel, and lodging; these are unavailable in the winter.

The Mesa Verde National Park Post Office has the ZIP Code 81330.^[33]

Neighboring Ute Mountain Tribal Park[link]

The Ute Mountain Tribal Park, adjoining Mesa Verde National Park to the east of the mountains, is approximately 125,000 acres (51,000 ha) along the Mancos River. Hundreds of surface sites, cliff dwellings, petroglyphs and wall paintings of Ancestral Puebloan and Ute cultures are preserved in the park. Native American Ute tour guides provide background information about the people, culture and history who lived in the park lands. National Geographic Traveler chose it as one of "80 World Destinations for Travel in the 21st Century", one of only nine places selected in the United States.^[34]

Culturally modified trees[link]

In February 2008, the Colorado Historical Society decided to invest a part of its US$7 million budget into a culturally modified trees project in the National Park.^[35]
