Chetro Ketl

The rear wall was nearly 500 feet long and may have supported five stories of rooms. Along the inside of the wall are long rows of rooms.

Chetro Ketl is located about one-quarter mile southeast of Pueblo Bonito.  It's and easy walk along the base of the mesa cliff to Pueblo Bonito.  Along the way there is an area where you can easily view some petroglyphs low on the cliff face.
