Tuzigoot National Monument preserves the largest and best-preserved Sinagua pueblo ruin in Arizona’s Verde Valley, a 110-room stone settlement built between about 1125 and 1400 CE on a ridge above the Verde River floodplain near Clarkdale. The pueblo extended along a natural outcrop, rose two to three stories, and was entered largely by ladders through roof openings rather than doors. Excavated from 1933 to 1935 by Louis Caywood and Edward Spicer with federal relief support, the site was prepared for public display in 1935 and 1936. It became a national monument in 1939 and remains a major archaeological site reflecting the Verde Valley’s deep human history.
