Saddle (landform)
The saddle between two hills or mountains is the region surrounding the saddle point, the lowest point on the line tracing the drainage divide (the col) connecting the peaks. When, and if, the saddle is navigable, even if only on foot, the saddle of a (optimal) pass between the two massifs, is the area generally found around the lowest route on which one could pass between the two summits, which includes that point which is a mathematically when graphed a relative high along one axis, and a relative low in the perpendicular axis, simultaneously; that point being by definition the col of the saddle. Topography A saddle is the lowest area between two highlands (prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls off in the lower direction. That is, the drainage divide is a ridge along the high point of the saddle, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adare Peninsula
The Adare Peninsula, sometimes called the Cape Adare Peninsula, is a high ice-covered peninsula, long, in the northeast part of Victoria Land, extending south from Cape Adare to Cape Roget. The peninsula is considered the southernmost point of the Borchgrevink Coast, named for Carsten Borchgrevink (1864-1934). The peninsula was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for Cape Adare. The Adare Peninsula consists of overlapping shield volcanoes that have been potassium–argon dated 6 to 13 million years old. Potassium–argon dates of 2.27 million years and perhaps 1.14 million years have also been obtained. The Adare Peninsula shields form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. Named features West coast Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land. On the west side of the peninsula is Ridley Beach, a cupsate be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiralty Mountains
The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica. This mountain group is bounded by the Ross Sea, the Southern Ocean, and by the Dennistoun, Ebbe, and Tucker glaciers. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. It was discovered in January 1841 by Captain James Ross, who named them for the Lords Commissioners of the Admiralty under whose orders he served. The Admiralty Mountains are divided into the Dunedin Range, Homerun Range, and Lyttelton Range. Mountains and peaks This range includes the following mountains and peaks: Mount Achilles Mount Achilles is a prominent pyramidal mountain rising from the divide between Fitch Glacier and Man-o-War Glacier.

Newnes Glacier
Robertson Bay is a large, roughly triangular bay that indents the north coast of Victoria Land between Cape Barrow (Antarctica), Cape Barrow and Cape Adare. Discovered in 1841 by Captain James Clark Ross, Royal Navy, who named it for Dr. John Robertson (surgeon), John Robertson, Surgeon on HMS Terror (1813), HMS ''Terror''.

Moubray Glacier
Moubray Glacier is a rather steep glacier flowing south to Moubray Bay from Adare Saddle on Adare Peninsula in Antarctica. It is one of the main contributors of ice to Moubray Piedmont Glacier. The glacier was named by the New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 1957 ... of 1957–58 for its proximity to Moubray Bay.

Cape Adare
Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica. Description Marking the north end of Borchgrevink Coast and the west end of Pennell Coast, the cape separates the Ross Sea to the east from the Southern Ocean to the west, and is backed by the high Admiralty Mountains. Cape Adare was an important landing site and base camp during early Antarctic exploration. Off the coast to the northeast are the Adare Seamounts and the Adare Trough. History Captain James Ross discovered Cape Adare in January 1841 and named it after his friend the Viscount Adare (the title is derived from Adare, Ireland). In January 1895, Norwegian explorers Henrik Bull and Carsten Borchgrevink from the ship '' Antarctic'' landed at Cape Adare as the first documented landing on Antarctica, collecting geological specimens. Borchgrevink returned to the cape leading his own expedition i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Williams
Cape Williams () is an ice-covered cape in Antarctica. It is the termination of Buell Peninsula at the east side of the terminus of Lillie Glacier at the lower ends of George Glacier and Zykov Glacier. The peninsula is 15 nautical miles (28 km) long and is situated at the extremity of the Pennell Coast portion of Victoria Land, lying between Cape Williams and Cape Adare Cape Adare is a prominent cape of black basalt forming the northern tip of the Adare Peninsula and the north-easternmost extremity of Victoria Land, East Antarctica. Description Marking the north end of Borchgrevink Coast and the west e .... It was discovered in February 1911 when the Terra Nova of the British Antarctic Expedition, 1910–13, explored the area westward of Cape North, and it was named for William Williams, Chief Engine-room Artificer on the Terra Nova.

Mountain Passes Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...
