Tsin Kletzin is a Chacoan Anasazi great house and archaeological site located in Chaco Canyon, northwestern New Mexico, United States. A ruined compound located on the Chacra Mesa and positioned above Casa Rinconada, it is 2.3 miles (3.7 km) due south of Pueblo Alto, on the opposite side of the canyon. It lies near Weritos Dam, a massive earthen structure that scientists believe provided Tsin Kletzin with all of its domestic water. The dam worked by retaining storm water runoff in a reservoir. However, massive amounts of silt accumulated during flash floods would have forced the residents to regularly rebuild the dam and dredge the drainage channel.

Etymology
