Discover more about Agate House

Agate House stands as a testament to the ingenuity of the ancestral Puebloans who inhabited this region between 1050 and 1300 AD. Located within Petrified Forest National Park, near Holbrook, Arizona, this unique eight-room pueblo is constructed almost entirely from petrified wood, set in place with mud mortar. The agatized wood, readily available in the area, served as a practical substitute for the more conventional sandstone used in other pueblos. Archaeological evidence suggests that Agate House was likely a year-round residence for a single family, rather than a temporary dwelling. Its size and the effort required to build and maintain it point to a more permanent occupation. Some theories propose it may have also served as a meeting place for the surrounding community. While artifacts discovered at the site are scarce, the structure provides valuable insights into the daily lives and building practices of these early inhabitants. The ruins were reconstructed in 1933-34 by the Civilian Conservation Corps (CCC), under the direction of archaeologist C.B. Cosgrove Jr. While the reconstruction utilized original materials, it may not be an entirely accurate replication of the original structure. Nevertheless, it allows visitors to envision the lives of those who once called it home. Today, Agate House stands alone on a small hill in the Rainbow Forest, but it was likely part of a larger community. Hundreds of similar sites with petrified wood structures, dating back to the same period, have been discovered within the park. Visitors can reach Agate House via the Agate House Trail, a 2-mile round trip hike from the Rainbow Forest Museum parking lot. The trail offers a chance to traverse the unique landscape of the Petrified Forest, with its scattered petrified wood and badlands.
