|Geologic age||Lower Ordovician and Upper Cambrian|
Sedimentary > Carbonate > Dolostone (Bed)Upper part is medium-light- to medium-dark-gray, fine- to medium-grained, locally coarse-grained, medium- to very thick bedded dolomite. Rhythmically bedded lower dolomite beds alternate between light and dark gray weathering, medium and very light gray, fine and medium grained, and thin and medium bedded, which are interbedded with shaly dolomite.
Sedimentary > Clastic > Mudstone > Shale (Bed)Very thin to very thick bedded dolomite containing minor orthoquartzite and shale. Shaly dolomite.
Sedimentary > Chemical > Chert (Lens)discontinuous, dark-gray chert lenses occur directly below upper contact.
Metamorphic > Metasedimentary > Metaclastic > Quartziteorthoquartzite; floating quartz sand grains and two sequences of medium-light- to very light gray, thin-bedded quartzite
