Morton Strait is the 9 km (4.9 nmi)-long and 6.2 km (3.3 nmi)-wide strait between Snow Island on the southwest and Rugged Island and Livingston Island on the northeast, in the South Shetland Islands, Antarctica.[1] The Aim Rocks and Long Rock lie in the strait.

The feature was named on a chart by James Weddell, published in 1825, and is now established in international usage.[1]

Location[edit]

The strait is centred at (62°41′50″S 61°13′12″W / 62.69722°S 61.22000°W / -62.69722; -61.22000) (British mapping in 1821 and 1968, Chilean mapping in 1971, Argentine mapping in 1980, and Bulgarian mapping in 2005 and 2009). The United States Geological Survey gives the location as 62°42′S 61°14′W / 62.700°S 61.233°W / -62.700; -61.233Coordinates: 62°42′S 61°14′W / 62.700°S 61.233°W / -62.700; -61.233.[1]
