Agate House is a partial reconstruction of an Indian pueblo built here almost ten centuries ago. Indians built dwelling walls like these of petrified wood sealed with mud mortar. Archeologists believe the original eight-room pueblo was built between A.D. 1050 and 1300. The absence of a kiva, an underground ceremonial chamber, and the relatively small amount of cultural debris found at Agate House indicate a brief occupancy. Reconstruction of its room occurred after archaeological excavation in 1934.
