Deformation in response to landscape evolution during glacial cycles on the U.S. Atlantic passive margin

Elevations of Pleistocene highstand formations that lie across the South Carolina and northern Georgia coastal plain lie well above those of reconstructed past sea levels. This discrepancy has been attributed to some combination of tectonics, glacial isostatic adjustment, and/or deviations in estima...
