Highest Mountains of the World

The world’s tallest mountains are some of the most majestic and beautiful things that one can be blessed enough to witness in their lifetime. They are all located in Asia and each reach an altitude of over eight thousand meters in height. There are only fourteen mountains in the world that can boast such a height. Below are the ten highest of these fourteen mountains.
Mount Everest. Standing at about 29,029 feet (8,848 meters), Everest boasts the top spot for the tallest mountain in the world. It is located on the border between Sagarmatha Zone, Nepal, and Tibet, China and is part of the Himalayan Mountain Range. Although it is the tallest mountain and attracts many climbers of both advanced and limited climbing skill, it is one of the easier mountains to climb. Don’t be mistaken by what we mean by easier, there is still the danger posed by weather changes, winds, temperature and altitude sickness that can make such a long climb difficult, but the terrain is a lot more simple to take than some of the other tallest mountains like K2 or Nanga Parbat.
K2 (Mount Godwin-Austen) is located on the border between Pakistan and China and is part of the Himalayan Mountain Range. It is the second highest mountain in the world and is a far more treacherous climb than Everest. In fact, one of every four people that attempts to reach the summit at about 28,251 feet (8,611 meters), dos not live to see the bottom again. Of all of the highest mountains, above eight thousand meters, K2 has the third highest mortality rate.
Kangchenjunga, once thought to be the tallest mountain in the world, was stated as the third highest mountain at 28,169 feet (8,586 meters) in 1848. Its name translates to “The Five Treasures of the Snow” and each of these peaks is said to represent the five repositories of God: gold, silver, gems, grain and holy books. This mountain is sacred to Kirant religion and because of this when the first expedition to the summit occurred in 1955; the British exploration team stopped a few feet away from the actual summit out of respect. A tradition which most teams that have successfully reached the summit have honorably followed.
Lhotse is the fourth highest mountain on Earth and is connected to Everest at the South Col. It is located on the boarder between Nepal and China and at it highest peak is about 27,940 feet (8,516 meters) high. This mountain is best known for its close proximity to Everest but is special in own right because it is the home of the steepest face of a mountain that is approximately 1.98×1.4 miles in size. This southern face has been the setting for any failed attempts, some notable fatalities and very few successful summit reaches.

Makalu is the fifth highest mountain in the world and is located about 14 miles east of Everest. It is located on the boarder of Nepal and China. It is an isolated peak that has the unique shape of a four-sided pyramid. There is another subsidiary peak that doesn’t quite meet up to the “eight-thousander” reputation called Kangchungtse, or Makalu II. It lies northeast of the main summit and is connected to it by a arrow saddle called Chomo Lonzo.
Cho Oyu is the sixth highest mountain in the world and stands at about 26,906 feet (8,201meters) high. Like most of the other Himalayan Mountains, it lies between Nepal and China (Tibet). Its name in Tibetan means “Turquoise Goddess”. It was used as a warm up for climbing Mount Everest when people were first exploring the Himalayan Mountains and today it is considered the easiest of al of the “eight-thousander” mountains to climb.
Dhaulagiri is the seventh highest mountain in the world and is about 26,795 feet (8,167 meters) tall. It is located just north of central Nepal. Its name means “White Mountain”. The South and West faces of Dhaulagiri both feature massive drops; each rises over 4000 meters from its base, and each has been the site of epic climbs. This mountain, along with Annapurna, is home to a more dramatic scene than most of the other mountains, for they face each other while separated by a valley. This is an amazing sight to see, and one of the main reasons why, for thirty years, it was thought to be the highest mountain in the world.
Manaslu, when translated means “Mountain of the Spirit” and is the eighth highest mountain in the world. It is a part of the Nepalese Himalayans and stands at about 26,759 feet (8,156 meters) high. The mountain’s long ridges and valley glaciers offer feasible approaches from all directions, and culminate in a peak that towers steeply above its surrounding landscape. This is the most dominant feature when viewed from far way.
Nanga Parbat is the world’s ninth tallest mountain and stands at about 26,660 feet (8,126 meters) in height. Although the name is Urdu for “Naked Mountain”, for first half of the twentieth century it was known as “Killer Mountain”. It was called this because it used to be an incredibly dangerous climb to the top. Now however, it is less dangerous to climb, but still very difficult. This mountain is an immense and dramatic peak that rises above its surrounding area in Pakistan.
Annapurna is a series of peaks, the highest of which is called Annapurna I, which is the tenth highest mountain in the world. It is located in central Nepal and is approximately 26,545 feet (8,091 meters) tall. Its peaks are some of the world’s most dangerous to climb. In fact, they have a fatality rate of about forty percent.

The wonderful world of Igloo

This is an interesting subject that you may never need to use. But, imagine how cool it would be if there were a situation you had the chance to build an igloo! At least now you would know how to!
Igloo building in Sarek
 An igloo (Inuit language: iglu) or snowhouse is a type of shelter built of snow, originally built by the Inuit.
Although igloos are usually associated with all Inuit, they were predominantly constructed by people of Canada's Central Arctic and Greenland's Thule area. Other Inuit people tended to use snow to insulate their houses, which were constructed from whalebone and hides. Snow is used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as −45 °C (−49 °F), but on the inside the temperature may range from −7 °C (19 °F) to16 °C (61 °F) when warmed by body heat alone.

Types
There are three traditional types of igloos, all of different sizes and all used for different purposes.
  • The smallest was constructed as a temporary shelter, usually only used for one or two nights. These were built and used during hunting trips, often on open sea ice.
  • Intermediate-sized igloos were for semi-permanent, family dwelling. This was usually a single room dwelling that housed one or two families. Often there were several of these in a small area, which formed an Inuit village.
  • The largest igloos were normally built in groups of two. One of the buildings was a temporary structure built for special occasions, the other built nearby for living. These might have had up to five rooms and housed up to 20 people. A large igloo might have been constructed from several smaller igloos attached by their tunnels, giving common access to the outside. These were used to hold community feasts and traditional dances.

Igloo-inside
The snow used to build an igloo must have sufficient strength to be cut and stacked in the right way. The best snow to use for this purpose is snow which has been blown by wind, which can serve to compact and interlock the. The hole left in the snow where the blocks are cut from is usually used as the lower half of the shelter. Sometimes, a short tunnel is built at the entrance to reduce wind and heat loss when the door is opened.

 Architecturally, the igloo is unique in that it is a dome that can be raised out of independent blocks leaning on each other and polished to fit without an additional supporting structure during construction. An igloo that is built correctly will support the weight of a person standing on the roof. Also, in the traditional Inuit igloo the heat from the kudlik (qulliq, stone lamp) causes the interior to melt slightly. This melting and refreezing builds up a layer of ice that contributes to the strength of the igloo.
The sleeping platform is a raised area. Because warmer air rises and cooler air settles, the entrance area acts as a cold trap whereas the sleeping area will hold whatever heat is generated by a stove, lamp or body heat.
The Central Inuit, especially those around the Davis Strait, lined the living area with skin, which could increase the temperature within from around 2 °C (36 °F) to 10–20 °C (50–68 °F).

Northernmost Settlements in the World

Northernmost Settlement in the World

 Ellesmere Island is part of the Qikiqtaaluk Region of the Canadian territory of Nunavut. Lying within the Canadian Arctic Archipelago it is considered part of the Queen Elizabeth Islands, with Cape Columbia being the most northerly point of land in Canada. It comprises an area of 196,235 km2 (75,767 sq mi), making it the world's tenth largest island and Canada's third largest island. The Arctic Cordillera mountain system covers much of Ellesmere Island, making it the most mountainous in the Canadian Arctic Archipelago. The Arctic willow is the only woody species to grow on Ellesmere Island.
Vikings from the Greenland colonies reached Ellesmere Island, Skraeling Island and Ruin Island during hunting expeditions and trading with the Inuit groups. The first European to sight the island after the height of the "Little Ice Age" was William Baffin, in 1616; said "Age" lasted until roughly 1850. Ellesmere Island was named in 1852 by Edward Inglefield's expedition after Francis Egerton, 1st Earl of Ellesmere. The American expedition led by Adolphus Greely in 1881 crossed the island from east to west.
Large portions of Ellesmere Island are covered with glaciers and ice, with Manson Icefield and Sydkap in the south; Prince of Wales Icefield and Agassiz Ice Cap along the central-east side of the island, along with substantial ice cover in Northern Ellesmere Island. The northwest coast of Ellesmere Island was covered by a massive, 500 km (310 mi) long ice shelf until the 20th century. The Ellesmere Ice Shelf was reduced by 90 percent in the twentieth century due to global warming, leaving the separate Alfred Ernest, Ayles, Milne, Ward Hunt, and Markham Ice Shelves.


In 2006, the population of Ellesmere Island was recorded as 146. There are three settlements on Ellesmere Island, Alert (pop. 5), Eureka(permanent pop. 0, but home to a small temporary population), and Grise Fiord (pop. 141). Politically, it is part of the Qikiqtaaluk Region.
Canadian Forces Station (CFS) Alert is the northernmost settlement in the world. With the end of the Cold War and the advent of new technologies allowing for remote interpretation of data, the overwintering population has been reduced to 50.
Eureka, which is the second northernmost settlement in the world, consists of three areas, "Eureka Aerodrome" which includes "Fort Eureka" (the quarters for military personnel maintaining the island's communications equipment), the Environment Canada Weather Station and the Polar Environmental Atmospheric Research Laboratory (PEARL), formally the Arctic Stratospheric Ozone (AStrO) Observatory.
