Lake powell rock wall collapse
Powell Rock (60°42′S 45°36′W) is a small submerged rock on the east side of Signy Island in the South Orkney Islands. It lies off the mouth of Starfish Cove, about 0.3 nautical miles (0.6 km) northeast of Balin Point. First charted by Petter Sorlle in 1912-13 and named "Powellboen," after his whale catcher Powell. The Falkland Islands Dependencies Survey (FIDS) fixed the position of breakers here during rough weather in 1947.
