Established with the goal of preserving the largest concentration of archaeological sites in the United States, Canyons of the Ancients stretches east and west of Cortez in south western Colorado. As of 2005, over 6,000 individual structures have been identified, within more than 20,000 sites, within the Monument. Consisting of 176,056 acres, the Canyons of the Ancients was established on June 9, 2000, by President Clinton. The Monument surrounds three of the sections of Hovenweep National Monument, and is administered by the Bureau of Land Management.
By the middle of the 8th century CE, the peoples called the Ancestral Puebloans moved into this area of south western Colorado. Beginning with clustered pit houses, which later evolved into above ground masonry dwellings, with connecting walls and south facing windows. Common dwelling shapes were "U," "E" and "L" shapes. In this developmental period, pottery became more diverse, bowls, jars, and table ware were created with black designs on a white background. There is evidence of water management and techniques to conserve water with the use of small reservoirs, check dams, and terrace construction. By the 14th Centruy CE, these native populations moved out of the region, south east into the Rio Grande Valley of New Mexico, and west into the high mesas of north eastern Arizona.
Lowry Pueblo: National Historic Landmark with 8 kivas, a great kiva, and 40 rooms built as high as three stories. The underground kiva has been dated around 1103, and due to it's size, is considered as a gathering place for religious ritual. The last occupation of the pueblo was in the early 13th century. This ruin was excavated from 1930 to 1936 by the Field Museum of Natural History of Chicago, by Paul S. Martin, and declared a National Historic Landmark on July 19, 1964. Today, Lowry Pueblo is part of the Canyons of the Nacients National Monument.
