| Utah/Colorado Work is ongoing in the central North American Cordillera of Utah and Colorado to characterize the topographical and climatic development in the foreland during the Laramide orogeny of Paleogene time. The Uinta, Flagstaff, Claron, and Axhandle basins of Utah, and the Piceance Creek basin of Colorado were all significant depocenters during the early Cenozoic, and each hosted substantial lakes during this time. By constructing and analyzing detailed stratigraphies of stable isotopic and trace element data, we are investigating the hydrology of these basins, including lake chemistry and drainage patterns within the hinterland and foreland, as well as features of regional climate during an important time in the geological record of mountain building and cooling global climate. Work in this area is the focus of a doctoral dissertation by Steve Davis.
