Urchin Rock

Urchin Rock is a rock awash near the north-east end of Grandidier Channel, west of the Berthelot Islands, of the Graham Coast of the British Antarctic Territory.

The rock was photographed from the air by the Falkland Islands and Dependencies Aerial Survey Expedition, 1956-57, and charted by a Royal Navy Hydrographic Survey Unit in 1957-58. It is so named because it is a hazard at the edge of the channel, an urchin being a roguish or mischievous boy. (On a Chilean chart of 1962 the rock is marked as 'Roca Erizo' meaning 'sea-urchin rock'; an understandable mistranslation.)
