Montezuma Castle National Monument protects a set of well-preserved dwellings located in Camp Verde, Arizona, which were built and used by the Sinagua people, a pre-Columbian culture closely related to the Hohokam and other indigenous peoples of the southwestern United States, between approximately AD 1100 and 1425. The main structure comprises five stories and about 20 rooms and was built over the course of three centuries. Several Hopi clans and Yavapai communities trace their ancestries to early immigrants from the Montezuma Castle/Beaver Creek area. Archaeological evidence proves that the Hohokam and Hakataya settled around or in the Verde Valley. Clan members periodically return to these ancestral homes for religious ceremonies. Tuzigoot National Monument (Yavapai: ʼHaktlakva, Western Apache: Tú Digiz) preserves a 2- to 3-story pueblo ruin on the summit of a limestone and sandstone ridge just east of Clarkdale, Arizona, 120 feet (37 m) above the Verde River floodplain. The Tuzigoot Site is an elongated complex of stone masonry rooms that were built along the spine of a natural outcrop in the Verde Valley. The central rooms stand higher than the others and they appear to have served public functions. The pueblo has 110 rooms. The National Park Service currently administers 58 acres (23 hectares), within an authorized boundary of 834 acres (338 hectares). ″Tú Digiz/Tuzigoot″ is a Tonto Apache term for "crooked waters," from nearby Pecks Lake, a cutoff meander of the Verde River; from Tú Digiz one principal Tonto Apache clan gets its name. The pueblo was built by the Sinagua people between 1125 and 1400 CE. Tuzigoot is the largest and best preserved of the many Sinagua pueblo ruins in the Verde Valley. The ruins at Tuzigoot incorporate very few doors; instead, the inhabitants used ladders accessed by trapdoor type openings in the roofs to enter each room.
