One last time into Mesa Verde National Park:
We visited the Cliff Palace overlook again:
Then went to the Spruce Tree House overlook:
Spruce Tree House, the third largest cliff dwelling (Cliff Palace and Long House are larger), was constructed between about 1211 and 1278 CE by the ancestors of the Pueblo peoples of the Southwest. The dwelling contains about 130 rooms and 8 kivas (kee-vahs), or ceremonial chambers, built into a natural alcove measuring 216 feet (66 meters) at greatest width and 89 feet (27 meters) at its greatest depth. It is thought to have been home for about 60 to 80 people.
