abstract:The Corner Cliffs () are a rocky mass surmounted by two flat-topped summits , immediately south of Saturn Glacier and lying northeast of Coal Nunatak in the southeast part of Alexander Island, Antarctica. The rocks of these cliffs were hidden from the line of sight by intervening ice slopes to the west, but the two rock ridges forming the northwest shoulder of this feature were first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.
Back at Ko Hong, just around the corner from Ao Bo Lae, the otherwise continuous circle of limestone cliffs that surround the island opens up slightly.
