Gannet Rock (43°38'N., 66°09'W.), about 3.5 miles W of the Spectacle Islands, has a sugar loaf peak, 15m high, near its S end, and a hillock, nearly the same height, near its N end. Two rocks, the higher of which dries 4m, lie close together, about 275m S of the peak. North Rock, which dries 1.8m, and Peter Stewarts Rock (South Rock), which dries about 1.8m, lie about 0.2 mile N and 0.7 mile S, respectively, of Gannet Rock. The sea generally breaks over both these rocks.
