Report on the 1916-17 Peabody Museum explorations of Basket-Maker burial and storage caves near Kayenta, northeastern Arizona, including Sunflower, Goat and White Dog Caves and caves in Sayodneechee and Sagiotsosi Canyons. It describes the sites, cists, burials and mummies, then catalogs the material culture: dress and ornaments, cradles, baskets, twined-woven bags, cloth, fur-string robes, netting, cordage, atlatls, stone and wooden tools, and ceremonial objects. Many plates and diagrams show twining structures and weft patterns. It closes with conclusions on the Basket-makers' culture and their relation to the later Cliff-dwellers.
