Cliff Palace
How did Ancestral Puebloan builders raise the largest cliff dwelling in North America — roughly 150 rooms and 23 kivas of shaped sandstone and mortar — inside a sheer canyon alcove reached only by pecked hand-and-toe holds, and why, within a few generations of finishing it, did they abandon it entirely?
