Ancestral Puebloan People of MesaVerde

On a cold wintry December day in 1888, Richard Wetherill and his brother-in-law, Charlie Mason, cowboys from the Alamo ranch in Southwestern Colorado, spent most of their afternoon rounding up strays on the high mesas and steep canyons above their winter camp on the Mancos River. The going was tough and blowing snow made hard work of finding their cattle. As they rested their horses on the edge of a mesa, they saw at the far side of the canyon a complex of stone buildings built under a large outcropping of rock. Under this protective rock overhang was a village of houses, towers, and kivas, all strung together like a huge apartment complex. The cowboys named the location Cliff Palace. Years later, Charlie Mason described their discovery, “From the rim of the canon we had our first view of Cliff Palace…. To me this is the grandest view of all among the ancient ruins of the Southwest. We rode around the head of the canon and found a way down over the cliffs to the level of the building. We spent several hours going from room to room and picked up several articles of interest, among them a stone axe with the handle still on it.”

No one knows for sure who constructed, with such skill, a community of buildings high up on the side of a canyon wall; buildings that have survived the harsh elements of the mesa country for over a 1000 years. Anthropologists and historians refer to the people as hunters gathers, basket makers, cliff dwellers, Anasazi, (Navajo for “ancient ones) or more formally, or Ancestral Puebloan People. All that is known about them is found in the ruins of their cliff dwellings. (The Anasazi occupied a large area of mesa and canyon lands known today as the four corners, where Colorado, Utah, Arizona and New Mexico meet.)

After the Cowboys discovered Cliff Palace, they used their winter camp in the Mancos Valley as a base from which to explore the canyon close to their initial discovery (later to be called Cliff Canyon).

Over the next two months, Wetherill, Mason and cowboys from the Alamo ranch dug through the ruins collecting artifacts, some of which they sold to a museum in Denver for $3000.00. (The artifacts helped launch the newly established Denver Historical Society museum) Other artifacts were kept in a barn on the Alamo ranch.

Below are some of the artifacts found by the cowboys from the Alamo Ranch.

Regardless of the monetary value of the artifacts in the ruins, the Wetherills, owners of the Alamo Ranch, understood the archaeological and historical value the ruins had to Colorado and to the nation. Richard Wetherill wrote to the directors of the Smithsonian and Harvard’s Peabody Museum requesting that these institutions sponsor him and his brothers or at least send their own specialists to work with them to excavate the cliff dwellings. Neither museum offered financial assistance or a team of professionals to help in excavating the ruins. Without outside help, the ruins would continue their march into obscurity; the Wetherills could not take the time away from ranching to explore further the ruins of Cliff Canyon. Not until Gustaf Nordenskiold from Sweden, an adventurer of sorts, heard about the cliff dwellings in the American Southwest, did Cliff Canyon and the Anasazi people get attention from the scientific community. In 1891, Nordenskiold made the long journey to America, crossed the continent on the newly established Santa Fe line to Durango, and forty miles by buggy to the Alamo ranch to meet with the Wetherill family. The family introduced Nordenskiold to the Cliff Dwellings, all of which were which named by the Wetherill family. The most impressive of the dwelling complex being Cliff Palace, Spruce Tree House, Square Tower House, Mug House and Sandal House. In all, the Wetherills counted 182 cliff dwellings. Today, the count is 600. After spending several years exploring the cliff dwellings and its artifacts, Nordenskiold wrote The Cliff Dwellers of the Mesa Verde, where he detailed each dwelling and the artifacts found at the different locations.

Typically, in each of the complexes, small rooms were built around a kiva; some rooms had access to the kiva by tunnels. They also constructed a small opening adjunct to the kiva called a sipapu, which symbolized the entrance to the underworld or mother earth. In most kivas there are stone benches, and an area that appears to be a fire pit. There are different theories on the use of the kiva. The most popular thought is that the round recessed circular room was used for religious purposes, and most likely as a place for social gatherings. At Cliff House complex, there are 23 kivas.
There are also areas in the dwelling complex, where grain was ground in order to make flour that they used for multiple food preparations.

Also found on the mesa above Cliff Canyon were the ruins of villages, perhaps occupied by the ancestors of those who built the cliff dwellings. Archaeologists believe that the first people to occupy Mesa Verde did so around 2000 years ago. Anthropologists call these early people the basket weavers. These people lived in caves, but eventually by 750 A.D. moved into pithouses, a below ground system of housing around a kiva. The mesa environment was ideal for farming and there was enough moisture at the higher elevation of 8000 ft. to sustain agriculture. The Basket weavers mastered farming to where they had an expanded food supply and an increase in population. The people also began making crude pottery and developed the technique of crafting bows and arrows. By 1000 A.D. the basket weavers moved out of the below ground pithouses to above ground constructions made of pole and adobe. In this era, anthropologists refer to the above ground builders as the Anasazi, who improved building techniques by taking advantage of the natural environment that had an abundance of sandstone rock, which was easily cut into stone to build houses. The Anasazi became skilled masons, crafting each stone to an equal size to construct walls of their structures. They experimented with natural resources to develop mortar made out of sand, small gravel and ash. (This strong mortar can be seen in the ruins of Mesa Verde today.)

The Kiva was important in the construction of the below ground pithouse. When they move to above ground living, the kiva became the only below ground element of their culture that transferred to Ancestral Puebloan culture.

Drying racks line the walls of the kiva at the Far View Site, which indicates multiple uses of this kiva.

Agriculture land was on the top of the mesas. Archeologists are still trying to determine the canal system that ran from the reservoir in the picture below to the farming fields.

The National Park Service designation this reservoir, along with four others in Mesa Verde as a National Historic Civil Engineering Landmark. The water management system developed by the Anasazi people is one of the oldest engineered public works in the United States.

The Anasazi people grew three staple crops--corn, beans and squash all in the same field. The tall corn became a pole or sorts for the beans and the shade from the tall corn stalks protected the squash. They over produced, storing grain for the years of drought when rain or snow was not plentiful enough to sustain a crop.

The golden age of the Anasazi was between 1100-1300 AD. During this period they constructed houses with larger rooms, more complex attached buildings that could accommodate 1000 people. Their villages were spread out over many miles stretching across the mesas. During this era, the Anasazi demonstrated improved craftsmanship in masonry, pottery, weaving and jewelry. The evidence seems to indicate that all was well with the people who thrived on the mesa tops, but then they abandoned their above ground life to return to the caves and started engineering buildings along the cliffs. They used the same techniques that they mastered on the mesa tops; stone masonry buildings that fit under the rock umbrella perturbing out from the canyon walls.

Archaeologists and historians do not know why the Anasazi people left their prosperous villages and sought shelter along the canyon walls. One plausible explanation is that the canyons offered a defensible and secure location. Climate may also have been a reason for the move. Winter could be harsh on the mesa tops; the cliff dwellings offered a warmer environment.


Note the black soot on the back wall of the canyon. They constructed most of the structures with at least 3 to 4 ft. clearance from the wall. Evidence shows that they built their fires behind these structures. With small openings at the back of their rooms, the heat from the fires would penetrate their living quarters giving them a warmer environment.

The cliff dwellers still farmed on the mesas above and near some of their dwelling under the rock outcropping. At Spruce House complex, there is also a spring at the bottom of the canyon, which offered a water supply.

The inhabitants of the cliff dwellings only stayed under the protective rock for a couple of generations. By 1300, they were gone from the mesa. It is not known where the people migrated to, but most recent scholarship indicates that they are the ancestors of the Pueblo people. The most logical reason for their migration south would be climate change. A drought settled over the mesa region from 1272 to 1299, a long time to go with out a reliable food source. Also, years of farming on the mesa would have depleted the soil of nutrients to successfully grow crops and deforesting the land would cause erosion; the people had to move on to new fresh land where there was ample moisture to sustain life and agriculture. It is most probable that the hunter gathers, the Basket weavers, the Cliff Dwellers and the Anasazi people are the ancestors of the Pueblo people, who today live in the American Southwest.
