Figure 1. Digital elevation map of the Great Basin showing the distribution of known paleovalleys and a few segments (from Lindgren, 1911; Faulds et al., 2005; Garside et al., 2005; and this study), the Eocene paleodivide proposed from this study, and the paleodivide of Christiansen and Yeats (1992). The east-draining paleovalleys flowed to the Uinta basin; the west-draining paleovalleys flowed to the Pacific Ocean, which was in the Great Valley of California at the time. Arrows show flow direction where known or reasonably inferred.
