|Geologic age||Middle Devonian|
Sedimentary > Clastic > Sandstone (Bed)Upper beds are grayish-red to grayish-purple sandstone containing quartz pebbles as large as 3 cm (1.2 in) in diameter. Lower beds are light-olive-gray- to yellowish-gray- and greenish-black-weathering, medium-gray to medium-bluish-gray very thin to very thick bedded siltstone and sandstone cross-bedded. More sandstone in upper beds becomes finer downward.
Sedimentary > Clastic > Siltstone (Bed)Lower beds are light-olive-gray- to yellowish-gray- and greenish-black-weathering, medium-gray to medium-bluish-gray very thin to very thick bedded siltstone.
Sedimentary > Clastic > Mudstone > Shale (Bed)Lower beds ; graded and interbedded with black to dark-gray shale that is locally fossiliferous.
