The Muav is a mottled, nodular, shaly, yellowish-gray limestone. In the eastern Canyon it is a yellowish cliff in the lower part, a covered slope in the middle, and a ledgy cliff, often stained red, in the upper part where it contacts the Redwall (or Temple Butte). Muav fossils include trilobites and brachiopods as well as scattered invertebrate tracks and trails. Of the Tonto formations, the Muav was deposited farthest from shore.
