Chart showing correlations of upper Cretaceous Fox Hills Sandstone and Lance Formation, and lower Tertiary Fort Union, Wasatch, and Green River formations, from the eastern flank of the Washakie Basin to the southeastern part of the Great Divide Basin, Wy

The stratigraphic sections show surface and subsurface correlations of some Upper Cretaceous and lower Tertiary rocks along the eastern flank of the Washakie basin and southeastern part of the Great Divide basin, Wyoming. These rock crop out from near Baggs, Wyoming, to near Creston Junction, Wyoming, 50 mi (80km) to the north. This report is a continuation of our stratigraphic investigations from south of Baggs, Wyoming to Craig, Colorado.
