Lassus Mountains

Last updated

The Lassus Mountains ( 69°35′S71°38′W / 69.583°S 71.633°W / -69.583; -71.633 ) are a large group of mountains, 15 nautical miles (28 km) long and 3 nautical miles (6 km) wide, rising to 2,100 metres (6,900 ft) and extending south from Palestrina Glacier in the northwest part of Alexander Island, Antarctica. They overlook Lazarev Bay and a few minor islands within the bay such as Dint Island and Umber Island; Haydn Inlet lies to the south while the Havre Mountains lie immediately north.

The mountains were probably first seen on 9 January 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen. They were photographed from the air in 1936 by the British Graham Land Expedition but mapped as part of the Havre Mountains. They were first mapped in detail, from air photos taken by the Ronne Antarctic Research Expedition (1947–48), by D. Searle of the Falkland Islands Dependencies Survey in 1960, and were named by the UK Antarctic Place-Names Committee after Orlandus Lassus, a Belgian composer of the 16th century. [1]

Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island.

The Prince Albert Mountains are a major mountain group in Antarctica over 320 km (200 mi) long. Located in Victoria Land, they run north–south between the Priestley and Ferrar glaciers.

<span class="mw-page-title-main">Umber Island</span>

Umber Island is a rocky island, 2.4 km long, lying 1.75 km (1.09 mi) southwest of Kamhi Point and 10 km northwest of Dint Island lying within Lazarev Bay, off the west side of Alexander Island, Antarctica. The island was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE) in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960, it was so named by the United Kingdom Antarctic Place-Names Committee because on the RARE photos the island appears in deep shadow cast by the Havre Mountains to the north.

The Rouen Mountains are a prominent mountain range, reaching to about 2,800 m and extending 35 miles (60 km) NW-SE from Mount Bayonne to Care Heights and Mount Cupola, in north Alexander Island, Antarctica. This mountain range is known to occupy some of the highest peaks of Alexander Island, much like the nearby Douglas Range. Mount Paris is the highest point of the Rouen Mountains, exceeding 2,800 m approximately.

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Lazarev Bay is a rectangular bay, 15 nautical miles (28 km) long and 13 nautical miles (24 km) wide, which separates Alexander Island from Rothschild Island and is bounded on the south side by the Wilkins Ice Shelf, which joins the east portion of Rothschild Island and the west portion of Alexander Island. Two minor islands, Dint Island and Umber Island, lie merged within the ice of the Wilkins Ice Shelf within Lazarev Bay.

Jutulstraumen Glacier is a large glacier in Queen Maud Land, Antarctica, about 120 nautical miles (220 km) long, draining northward to the Fimbul Ice Shelf between the Kirwan Escarpment, Borg Massif and Ahlmann Ridge on the west and the Sverdrup Mountains on the east. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Jutulstraumen. More specifically jutulen are troll-like figures from Norwegian folk tales. The ice stream reaches speeds of around 4 metres per day near the coast where it is heavily crevassed.
