Antarctic Peninsula with Palmer Land visible below and south of Graham LandThe Antarctic Peninsula is shown at the left side of the map of Antarctica; Palmer Land (unlabeled) is visible between Graham Land and Marie Byrd Land
Boundaries
In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill.
This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deception Island in the sloop Hero in November 1820.[1]
