|Tithonian - Oxfordian|
145 - 163.5 Ma
Age: Jurassic (145 - 163.5 Ma)
Stratigraphic Name: Morrison Formation
Description: Commonly cliff-forming, cross-bedded sandstone lenses alternating with slope-forming siltstone, mudstone and shale. Colors are highly variable, and include greenish gray, reddish brown, pink, white, and purple. Sands were deposited by braided streams with finer sediment representing overbank or lacustrine deposits. (145-160 Ma)
