Perplex Ridge is a mountain ridge on Pourquoi Pas Island off the Fallières coast of West Antarctic Graham Land . It consists of four massifs up to 915 m high , separated from each other by small glaciers . The ridge extends from Lainez Point in a northerly direction over a length of 10 km along the northwest side of the island.
Participants in the Fifth French Antarctic Expedition (1908–1910), led by polar explorer Jean-Baptiste Charcot , sighted the ridge for the first time in 1909 and carried out rough mapping. Participants in the British Graham Land Expedition (1934–1937) under the direction of the Australian polar explorer John Rymill specified the measurements in 1936. The same applies in 1948 to the Falkland Islands Dependencies Survey , which also made the name. The name given to the surveyors' surprise at being able to identify the mountain ridge on the basis of previous maps.
