Cape Crozier

From Wikipedia, the free encyclopedia

Cape Crozier is the most easterly point of Ross Island in Antarctica, at 77°30′S, 169°20′E. It was discovered in 1841 during James Clark Ross's expedition with HMS Erebus and HMS Terror, and was named after Francis Crozier, captain of HMS Terror. The extinct volcano Mount Terror, also named during the Ross expedition, rises sharply from the Cape to a height of 10,597 feet (3230m)[1][2], and the edge of the Ross Ice Shelf (then known as the Barrier or Great Ice Barrier) stretches away to its east.

[edit] First landing, 1902

The first landing at Cape Crozier was on 22 June 1902, during Captain Scott's Discovery Expedition. A party from RRS Discovery landed by small boat on a stony beach area a little to the west of the Cape. A postbox was set up there, prominently marked, for messages to be collected by any future relief ship. Scott, Edward Wilson and Charles Royds climbed the slope to a vantage point from which they could view the Barrier surface, and they were also able to observe the large Emperor Penguin colony which inhabited the sea ice below and around Cape Crozier. This colony was of abiding interest to Wilson, who made two subsequent land journeys from the expedition's eventual base in McMurdo Sound to make closer observations of the colony, which he was to visit again in 1911.

[edit] Terra Nova Expedition, 1910-13

Captain Scott seriously considered Cape Crozier as the base for his second Antarctic expedition[3]. On the previous trip the Discovery, in McMurdo Sound, had been frozen into its berth for more than two years, and had barely escaped in February 1904, a circumstance that had led to an expensive relief operation and some opprobrium for Scott. There would be no chance of the Terra Nova being icebound in the open seas off Cape Crozier, but the unsheltered location would make landings of stores and personnel difficult, the shore base would be at the mercy of rough weather, and the land route to the Barrier surface was problematic. Scott decided to return to McMurdo Sound for his base, though to a more northerly anchorage (Cape Evans).

[edit] Winter journey, 1911

Wilson was keen to continue researching the Emperor Penguin embryo, and needed to obtain eggs at an early stage of incubation, which meant collecting them in the depth of the Antarctic winter. In the Zoology section of the Discovery Expedition's published Scientific Report he suggested a plan for a "winter journey" whereby these eggs could be retrieved[4]. This journey, with Captain Scott's approval[5], was undertaken between 27th June and 2 August 1911, by Wilson, Apsley Cherry-Garrard and Henry Robertson Bowers. Cherry-Garrard later described the trek in his book, The Worst Journey in the World. In the winter darkness and extreme weather conditions the journey proved slow and hazardous, but despite mishaps three eggs were retrieved and later presented by Cherry-Garrard to the Natural History Museum[6]. Ultimately, however, their scientific value proved minimal[7].

[edit] Restricted site

Cape Crozier is within a restricted area and permission is required to visit it. It is part of a Site of Special Scientific Interest classified by SCAR (Scientific Committee for Antarctic Research). Cape Crozier is home to one of the largest Adelie Penguins colonies in the world (~150,000 breeding pairs), a smaller Emperor Penguin colony (~600 breeding pairs), and one of the largest South Polar Skua colonies in the world (~1,000 breeding pairs)[8]. It also hosts several rare species of lichens.
