Casa Rinconada is a Chacoan Anasazi archaeological site located atop a ridge adjacent to a small rincon across from Pueblo Bonito in Chaco Culture National Historical Park, northwestern New Mexico, United States.
It is an isolated great kiva (out of four in Chaco Canyon) with all typical element of great kivas: masonry firebox, inner bench, four roof-supporting large seating pits, masonry vaults and 34 (divided into two sizes)niches encircling the kiva. There is also an unusual 39 feet (12 m) long underground passage, perhaps used in the ceremonies to allow performers sudden entry thus surprising the audience. It was dig out in the sandstone and shale that compose the ridge the kiva sits in.
Casa Rinconada was excavated in 1930-31 by archaeologists Vivian and Reiter and the University of New Mexico/School of American Research field schools, reconstructed in part by Vivian in 1933, while Richter of National Park Service worked on capping outer walls in 1955.
Casa Rinconada is accessible through the Canyon Loop Drive and 1/2 mile trail (round trip) off the Drive.
