Tuzigoot National Monument

The name means "crooked waters" in Tonto Apache — a reference to a nearby cutoff meander of the Verde River. On a limestone and sandstone ridge 120 feet above the Verde River floodplain, the Sinagua people built a 110-room pueblo between 1125 and 1400 CE, the largest and best preserved of their ruins in the Verde Valley. Rooms had no doors; inhabitants entered through trapdoor openings in the roofs. Excavated in the 1930s under federal relief funding, it became a National Monument in 1939.
