Spilite Arch
From Wikishire
Spilite Arch is a natural stone arch at the eastern end of Annenkov Island, formed by a pillar of rock, 100 feet high, joined to the adjacent cliffs by a spilite sill.
The arch was named following geological work on the island by the British Antarctic Survey in the 1972-73 season.
