Chetro Ketl

Chetro Ketl is an Ancestral Puebloan great house and archeological site located in Chaco Culture National Historical Park, New Mexico, United States.

Edgar L. Hewett, the director of the first archeological field school in the canyon, conducted excavations of Chetro Ketl during 1920 and 1921, and again between 1929 and 1935. Chaco scholars estimate that it required more than 500,000 man-hours, 26,000 trees, and 50 million sandstone blocks to erect Chetro Ketl. The great house is a D-shaped structure; its east wall is 280 feet (85 m) long, and the north wall is more than 450 feet (140 m); the perimeter is 1,540 feet (470 m), and the diameter of the great kiva is 62.5...
