Well-preserved cliff dwellings were occupied by the Salado culture during the 13th, 14th, and early 15th centuries. The people farmed in the Salt River Valley and supplemented their diet by hunting and gathering native wildlife and plants. The Salado were fine craftsmen, producing some of the most exquisite polychrome pottery and intricately woven textiles to be found in the Southwest.
The monument is located in the Upper Sonoran ecosystem, known primarily for its characteristic saguaro cactus. Other common plants include: cholla, prickly pear, hedgehog, and barrel cactus (blooming April through June); yucca, sotol, and agave; creosote bush and ocotillo; palo verde and mesquite trees; an amazing variety of colorful wild flowers (February through March); and a lush riparian area which supports large Arizona black walnut, sycamore, and hackberry trees.
