Controls on interior West Antarctic Ice Sheet Elevations: inferences from geologic constraints and ice sheet modeling

► The exposure age distributions <100 ka at MBL and the Ohio Range are similar. ► Clusters of exposure ages record higher WAIS elevations. ► There is an excellent agreement between an ice sheet model and geologic constraints. ► Ice elevations near Mt. Waesche ranged from +85 m to >200 m below present ice level.
