This five-day field trip examines Pennsylvanian to Jurassic strata in the Paradox Basin on the Colorado Plateau in southeastern Utah. The trip will emphasize four major themes: 1) Permian-Triassic stratigraphy, 2) characteristics of non-marine depositional systems, 3) paleogeography, and 4) paleoclimate. The trip follows depositional facies in the Permian and Triassic section from proximal continental settings near the Ancestral Rocky Mountains in the Uncompahgre Highlands to distal marine settings within the Paradox Basin. Evolution of these depositional systems along the west coast of Pangea from the late Paleozoic to the early Mesozoic is a key indicator of the paleogeographic...
