Chaco Canyon: Great Houses
built 634 days ago
The Chacoans built their complexes along a nine-mile (14 km) stretch of canyon floor, with the walls of some structures aligned cardinally and others aligned with the 18.6 year cycle of minimum and maximum moonrise and moonset. Nine Great Houses are positioned along the north side of Chaco Wash, at the base of massive sandstone mesas. Other Great Houses are found on mesa tops or in nearby washes and drainage areas. There are 14 recognized Great Houses, which are grouped below according to geographic positioning with respect to the canyon.

At least a dozen conglomerations of houses, storerooms, workrooms and religious chambers have been found in the Chaco Canyon. Some of them include hundreds of rooms, built of stone - not higgledy-piggledy, but finely crafted according to a design that seemed to have been worked out in advance.
