Intrusion Lake (54°29′S, 37°4′W) is a lake, 0.2 miles (0.3 km) long, located north-northeast of Olstad Peak in central Annenkov Island, South Georgia. Mapped by British Antarctic Survey (BAS) in 1972-73 and so named because its irregular shape is controlled by several intrusions of andesite along its north shore.
