Morton Strait
Morton Strait is the 9-kilometre-long (4.9 nmi) and 6.2-kilometre-wide (3.3 nmi) 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]

(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 Lua error in Module:Coordinates at line 489: attempt to index field 'wikibase' (a nil value)..[1]

[edit | edit source]Aim Rocks
[edit | edit source]Aim Rocks (Lua error: callParserFunction: function "#coordinates" was not found.) is a group of rocks lying east of Cape Timblón in the middle of Morton Strait. The name, given by the United Kingdom Antarctic Place-Names Committee in 1961, is descriptive; these rocks in line are a guide for safe passage through the southern entrance of Morton Strait.[2] Interactive image.
Long Rock
[edit | edit source]Long Rock (Lua error: callParserFunction: function "#coordinates" was not found.) is a large rock extending 720 m (787 yd) in east–west direction, 180 m (197 yd) wide and rising to 13 m (42.7 ft) in the northeast of Morton Strait. The area was visited by early 19th century sealers operating on Byers Peninsula. The rock is located 1.6 km (0.99 mi) south-southwest of Vardim Rocks, 2.1 km (1.30 mi) south-southwest of Devils Point, 4.2 km (2.61 mi) north of President Head, Snow Island, 7 km (4.35 mi) east-northeast of Cape Timblón, Snow Island and 6.93 km (4.31 mi) southeast of Benson Point, Rugged Island (British mapping in 1933 and 1968, Argentine in 1946 and 1953, Chilean in 1947 and 1971, French in 1951, detailed Spanish mapping in 1992, and Bulgarian mapping in 2005 and 2009). The feature was named by Discovery Investigations personnel that charted Morton Strait in 1930–31.[3] Interactive image.
