Cliff Palace
Cliff Palace: A Natural Wonder Formed by Time
Cliff Palace was built within a massive alcove created by nature over millions of years. The overhanging cliff is composed of Cliff House sandstone, deposited roughly 78 million years ago during the Cretaceous Period. Water seeping through the porous sandstone and pooling above an impermeable shale layer, caused chunks of sandstone to crack and eventually collapse during winter freezes—forming the massive alcoves ideal for shelter.
