|Holocene surficial deposits|
Age: Anthropocene (0 - 0.0117 Ma)
Description: Unconsolidated deposits associated with modern fluvial systems. This unit consists primarily of fine-grained, well-sorted sediment on alluvial plains, but also includes gravelly channel, terrace, and alluvial fan deposits on middle and upper piedmonts. (0-10 ka)
Comments: Associated with modern fluvial systems Original map source: Arizona Geological Survey, DI-8 Geologic Map of Arizona, Digital Spatial data for the Geologic Map of Arizona, v. 3.0, edited by S.M.

201.3 - 237 Ma
|Owl Rock Member|
Age: Late Triassic (201.3 - 237 Ma)
Stratigraphic Name: Owl Rock Member
Description: Gray-red and light-purple, slope- and ledge-forming, nodular limestone, interbedded with purple, light-blue, and light-red calcareous claystone, siltstone, and sandstone. Limestone beds are gray, cherty, lenticular, silty, irregularly bedded, and 0.5 to 1.5 m (1 to 5 ft) thick, and they extend laterally several kilometers, forming as many as seven resistant limestone ledges at Newberry Mesa and northern part of Ives Mesa (fig. 1). Includes upper red, slope-forming siltstone and claystone interval that gradually thickens from 12 m (40 ft) in northwestern part of quadrangle (sheet 1) to 43 m (240 ft) near east-central edge of quadrangle (sheet 2). Unit contains abundant mud pellets and silicified clay and concretionary chert nodules and generally maintains consistent thickness across quadrangle. Contact with the underlying Petrified Forest Member (^cp) is gradational and is arbitrarily placed at lowest limestone bed, or at nodular calcareous gray-white siltstone in slope below lowest limestone bed. Thickness, 80 to 92 m (260 to 300 ft)
