Photograph by Charles A. and Anne Morrow Lindbergh, 1929. In 1929 Chetro Ketl was in the early stages of excavation by Edgar Lee Hewett, a field program that would continue until 1934. Hewett had conducted research at the site in 1920 and 1921, and undoubtedly some of the cleared rooms and kivas date from this earlier fieldwork, but a truck, people, and some field equipment are visible signs of the renewed work. Chetro Ketl has never been as completely excavated as Pueblo Bonito, its near neighbor, but it appears to be very similar to it. It too is D shaped, has two great kivas, and at least ten other kivas, and originally included perhaps as many as six hundred rooms.
