Observation Bluff (60°43′S 45°36′W / 60.717°S 45.6°W) is the eastern summit, 110 m, of the ice-free ridge which forms the north side of Paal Harbour in Signy Island, in the South Orkney Islands. The area was roughly surveyed by DI personnel in 1933. The bluff was surveyed in 1947 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because it marks the position from which daily sea ice observations were made.
