Casa Rinconada, great kiva AD 1140-1200, Chaco Culture National Historical Park, New Mexico, USA.
Ancient Puebloan kiva for religious rituals. Casa Rinconada, occupied about AD 1140-1200, is an isolated great kiva (out of four in Chaco Canyon), built 63 feet (19 m) in diameter with a circular inner bench, masonry firebox, masonry vaults, 34 niches, four large pits for seating roof supports, plus an unusual 39-foot (12 m) passage dug underground through sandstone and shale. Chaco Culture National Historical Park hosts the densest and most exceptional concentration of pueblos in the American Southwest and is a UNESCO World Heritage Site. Chaco Canyon is in remote northwestern New Mexico, between Albuquerque and Farmington, USA. From 850 AD to 1250 AD, Chaco Canyon advanced then declined as a major center of culture for the Ancient Pueblo Peoples. Chacoans quarried sandstone blocks and hauled timber from great distances, assembling fifteen major complexes that remained the largest buildings in North America until the 1800s. Climate change may have led to its abandonment, beginning with a 50-year drought starting in 1130.Add to Cart Add to Lightbox Download
