Agate House, Petrified Forest National Park

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. ()
