The Sundance Sea



Any idea the number of transgressive/regressive phases define the mid- to late-Jurassic Sundance Sea?

Was the large alkaline, saline lake, " Lake T'oo'dichi' " which was formed in the late Jurassic, Brushy Basin member of the Morrison Formation, a result of the final regression of the Sundance Sea, a product of a monsoonal environment that existed it the Colorado Plateau area, or some other explanation?
