These include the remote Chaco Canyon in New Mexico, home to the ruins of a community said to have been the center of the Ancient Puebloan culture, and the lesser-known River House in Utah, a multi-room cliff dwelling which can only be reached by river.

The latter is often described as one of the most impressive Native American sites in the entire US.
