Sullivan Heights is a compact group of mountains in western Antarctica rising to 2,760 m (9,060 ft) in Mount Levack centered 11.5 nautical miles east-northeast of Mount Tyree in the Sentinel Range, Ellsworth Mountains. Roughly elliptical in plan and 11 nautical miles long, the feature includes sharp mountain peaks, rugged ridges, and steep peripheral scarps. The heights are encompassed by the flow of the Crosswell, Ellen, and Dater Glaciers, with their interior drained also by Pulpudeva and Strinava Glaciers. Separated from Vinson Massif to the south-southwest by Vranya Pass.
