The Sinker Rock (from English sinker 'sinker, sinker, sinker weight' ) is a cliff rock in the Palmer Archipelago off the Danco coast of the Antarctic Peninsula . It is located off the northern tip of Goudier Island near the center of Port Lockroy in the west of Wiencke Island .
Participants of the Fourth French Antarctic Expedition (1903–1905) under the direction of polar explorer Jean-Baptiste Charcot mapped several rocks here. The Falkland Islands Dependencies Survey named it after a plumb line that was installed around the rock as a mooring line .
