The Sundance Sea

[john-schneiderman@cox.net]

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?
