The earliest peoples arrived in the Verde Valley about 11,500 years ago and practiced a hunting and gathering economy until approximately A.D. 1, when agriculture appeared. The Sinagua, whose Spanish name means "without water," appeared at this time and farmed and traded extensively in this area until about A.D. 1400. Their structures included Palatki Ruin, with painted rock art called pictographs, and Honanki, which included at least 60 rooms and more pictographs. Other important Sinagua sites in the region include Montezuma's Castle and Montezuma's Well, examples of cliff dwellings and early irrigated farming, Tuzigoot, a pueblo typical of Verde Valley communities during the last phase of Sinagua occupation, and the V Bar V Ranch petroglyph site, noted for its finely crafted animal and geometric forms.
