It is believed that Cliff Palace was constructed and lived in from about 1200 A.D. to 1300 A.D. Cliff Palace was abandoned by 1300, though debate is ongoing as to the cause. Some contend that a series of
megadroughts interrupting food production systems was the main cause. Wetherill and Mason also rediscovered Spruce Tree House and Square Tower House, which are also located in
Mesa Verde. According to Wetherill and Mason, they "followed the Indian trail down Chapin Mesa, between Cliff and
Navajo canyons, and camped at the head of a small branch of the Cliff Palace fork of Cliff Cañon." Wetherill and Mason spent time after finding the dwellings looking at artifacts found within the cliff. According to Mason, they found a stone axe "with the handle still on it" and also observed "parts of several human skeletons scattered about." Wetherill and Mason collected various artifacts from the site over the years, and they kept a detailed record of their discoveries. Wetherill took the first collection of artifacts to
Durango, Colorado on March 2, 1889.
Preservation Throughout the decade following Cliff Palace's rediscovery, it became a popular destination for tourists and curious explorers. These visitors did not take care of the site as it is taken care of today. This led many of the fragile walls and other structures to crumble. Many of the visitors also took artifacts that they had found, leaving hardly any for future visiting archeologists to find and examine.
Richard Wetherill and others became very disturbed by this fact, and they pushed for the establishment of
Mesa Verde National Park in order to protect Cliff Palace and other archeological sites in the area. Finally, in 1906, Mesa Verde National Park was established. ==Description==
