Hogs Mouth Rocks

The Hogs Mouth Rocks are a chain of rocks which extend south from Invisible Island in the Bay of Isles, South Georgia. They were first roughly charted in 1912–13 by Robert Cushman Murphy, an American naturalist abroad the brig Daisy, and were probably named by Discovery Investigations personnel who surveyed the Bay of Isles in 1929–30.
