paragraph_text: The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise. Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, called the continental rise. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the slope and the shelf, on the order of 0.5 -- 1 °.

paragraph_text: Lambert Glacier is a major glacier in East Antarctica. At about 60 miles (100 km) wide, over 250 miles (400 km) long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier. It drains 8% of the Antarctic ice sheet to the east and south of the Prince Charles Mountains and flows northward to the Amery Ice Shelf. It flows in part of Lambert Graben and exits the continent at Prydz Bay.

paragraph_text: Zealandia (/ ziːˈlændiə /), also known as the New Zealand continent or Tasmantis, is a nearly submerged mass of continental crust that sank after breaking away from Australia 60 -- 85 million years ago, having separated from Antarctica between 85 and 130 million years ago. It has variously been described as a continental fragment, a microcontinent and a continent. The name and concept for Zealandia were proposed by Bruce Luyendyk in 1995.

paragraph_text: Earlier theories (e.g. by Alfred Wegener and Alexander du Toit) of continental drift postulated that continents ``ploughed ''through the sea. The idea that the seafloor itself moves (and also carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s. The theory is well accepted now, and the phenomenon is known to be caused by convection currents in the asthenosphere, which is ductile, or plastic, and the brittle lithosphere (crust and upper mantle).

paragraph_text: Wilkins Runway is a single runway aerodrome operated by Australia, located on upper glacier of the ice sheet Preston Heath, Budd Coast, Wilkes Land, on the continent of Antarctica, but southeast of the actual coast. It is named after Sir Hubert Wilkins, a pioneer of Antarctic aviation and exploration.

paragraph_text: On Earth, 99% of glacial ice is contained within vast ice sheets in the polar regions, but glaciers may be found in mountain ranges on every continent except Australia, and on a few high-latitude oceanic islands. Between 35°N and 35°S, glaciers occur only in the Himalayas, Andes, Rocky Mountains, a few high mountains in East Africa, Mexico, New Guinea and on Zard Kuh in Iran. Glaciers cover about 10 percent of Earth's land surface. Continental glaciers cover nearly 13,000,000 km2 (5×10^6 sq mi) or about 98 percent of Antarctica's 13,200,000 km2 (5.1×10^6 sq mi), with an average thickness of 2,100 m (7,000 ft). Greenland and Patagonia also have huge expanses of continental glaciers.

paragraph_text: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.

paragraph_text: The Sidelhorn is a mountain of the Bernese Alps, located west of the Grimsel Pass. It lies at the eastern end of the mountain chain between the Unteraar Glacier and the Rhone valley, named "Aargrat". Because the glacier drains into the Aar and hence the Rhine and North Sea, whilst the Rhone flows into the Mediterranean Sea, the Sidelhorn lies on the European continental divide.

paragraph_text: Africa is the world's second largest and second most - populous continent (behind Asia in both categories). At about 30.3 million km (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Isthmus of Suez and the Red Sea to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognised sovereign states (countries), nine territories and two de facto independent states with limited or no recognition. The majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere.

paragraph_text: Zalmoxis Peak (, ‘Vrah Zalmoxis’ \'vr&h zal-'mok-sis\) is the rocky peak rising to 2500 m in Bearskin Ridge on the east side of Sentinel Range in Ellsworth Mountains, Antarctica. It is surmounting Patton Glacier to the northwest and Crosswell Glacier to the southeast.

paragraph_text: McClintock Peak () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. McClintock Peak is situated along the Continental Divide. The Lake of the Seven Winds sits below the east slopes of the peak and Mount Morgan is to the south.

paragraph_text: Continental drift is the movement of the Earth's continents relative to each other, thus appearing to ``drift ''across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was rejected by some for lack of a mechanism (though this was supplied later by Arthur Holmes). The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents move.

paragraph_text: World Park Base was a non-governmental year-round Antarctic base located at Cape Evans on Ross Island in the Ross Dependency. The international environmental organization Greenpeace established World Park Base in 1987 in order to press its demand for the Antarctic Treaty nations to declare all of the continent of Antarctica a World Park. This would make the entire continent off-limits to commercial exploitation and pollution, and permit only limited scientific research. Greenpeace closed down and completely dismantled the base in 1992.

paragraph_text: The Cambrian is a major division of the geologic timescale that begins about 541.0 ± 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.

paragraph_text: The Billboard () is a massive granite monolith in the Sarnoff Mountains of the Ford Ranges of Marie Byrd Land, West Antarctica, standing just west of Mount Rea between Arthur Glacier and Boyd Glacier. It was discovered in November 1934 by a Second Byrd Antarctic Expedition (1933–35) sledge party under Paul Siple, and is so named because of its form and appearance with vertical faces rising above the continental ice.

paragraph_text: Ramorino Glacier () is the long glacier situated northwest of upper Crosswell Glacier and southeast of Cervellati Glacier on the east slope of Sentinel Range in the Ellsworth Mountains, Antarctica. It flows northeastwards between Epperly Ridge and Shinn Ridge, and enters Crosswell Glacier northwest of Mount Segers. The feature was named by US-ACAN in 2006 after Maria Chiara Ramorino, manager of the Italian team that compiled and promulgated the SCAR Composite Gazetteer of Antarctica, 1998-2006.

paragraph_text: Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.

paragraph_text: This is a list of island countries. An island is a land mass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with the Federated States of Micronesia and the Indonesia (which consists of thousands of islands). Others consist of a single island, such as Nauru, or part of an island, such as Haiti. Although Australia is designated as a continent, it is often referred to as an island, as it has no land borders. Some declared island countries are not universally recognized as politically independent, such as Northern Cyprus. Some states, such as Taiwan, officially claim to hold continental territories but are de facto limited to control over islands.

Question: what is the continental limit where the Crosswell Glacier is found?
Answer: 60th parallel south
