Isotopic and elemental records of authigenic calcite from lacustrine deposits in the intraforeland basins of Utah were analyzed in an effort to reconstruct the regional paleoclimate, paleohydrology, and paleotopography of the early Cenozoic central North American Cordillera. Isotopic profiles for Paleogene Lakes Uinta, Flagstaff, and Claron show relatively large oxygen isotopic shifts that are diachronous among basins with an ~7{per thousand} decrease in {delta}18Ocalcite values at ca. 45 Ma in Lake Flagstaff, an ~5{per thousand} decrease in {delta}18Ocalcite values between ca. 42 and 35 Ma in Lake Claron, and an ~6{per thousand} decrease in {delta}18Ocalcite values between ca. 44 and 43 Ma in Lake Uinta. We interpret...
