Summary:
Pg. 7, 12-13. Sycamore Creek sandstone. Name proposed by A.A. Stoyanow in unpublished manuscript. The formation is generally dull reddish brown in color, although some buff-colored beds are present. Is made up of a coarse quartz sand cemented chiefly by oxides of iron and carbonate of lime. Cross-bedding is locally common, and then the stratification is not well defined. Traversed by numerous joints. Pebbly layers common. Is conformably overlain by thin-bedded flaggy limestones containing fossils identified by Stoyanow as Upper Devonian. Occurs as isolated remnants south and southeast of Payson, while to north is a large area partly overlain by Redwall limestone. Upper part has been largely removed by erosion, and where overlain by Redwall limestone [Mississippian] the thickness is seldom over 150 feet. Contains fossil fishes identified by Stoyanow as undoubtably Upper Devonian. Rests unconformably on pre-Cambrian diorite and in places on older rocks. On recent map of Arizona is classified as Tapeats sandstone (Upper Cambrian). Age is Late Devonian.
