In a place in the southwest of the U.S., this place is the only place in the U.S. that four corners connect.  The places are UTAH, COLORADO, NEW MEXICO, and ARIZONA where the Anasazi once lived.

The land where the Anasazi lived was mostly desert and has lots of deep canyons like Canyon de Chelly which was near the four corners regon.  Some Anasazi lived in Canyon de Chelly.

The Anasazi made pottery covered with designs that are painted white and black which were made in their cliff dwellings.

The Anasazi used flat stone to sharpen and protect themselves.
