Agate House Pueblo

Agate House is a partially reconstructed Puebloan building in Petrified Forest National Park, built almost entirely of petrified wood. The eight-room pueblo has been dated to approximately the year 900 and occupied through 1200, of the Pueblo II and Pueblo III periods. The agatized wood was laid in a clay mortar, in lieu of the more usual sandstone-and-mortar masonry of the area.
The ruins of Agate House were reconstructed by the Civilian Conservation Corps in 1933-34 under the direction of C.B. Cosgrove Jr. of the New Mexico Laboratory of Anthropology. Room 7 was fully reconstructed with a new roof. Room 2's walls were rebuilt to a height of five feet, but not roofed, and the remaining walls were rebuilt to a height of two or three feet.
