 Several minerals used for paint pigments were excavated from Chetro Ketl, including charcoal, shale, malachite, iron oxides, hematite, limonite, gypsum, and azurite.Twined sandals, and bones from the ferruginous hawk and the great horned owl have been found there.The relative lack of exotic material uncovered at Chetro Ketl, such as shells, copper bells, and macaw feathers, may indicate its lesser importance compared to Pueblo Bonito, where those items have been found in abundance.
