Mount Everest is the highest peak in the world. With an elevation of 8,848m Mount Everest is one of the most difficult mountains to climb. Located in Nepal and Tibet Mount Everest is also called as Sagarmatha (‘head in blue sky’ or ‘peak of Heaven’) in Nepal. In China it is called as Chomolungma (Goddess of Valley). The third highest Himalayan peak Kanchenjunga lies Partly in India and Nepal.
In the year 1865, The Royal Geographical Society of UK gave Mt Everest its English name in honour of George Everest, a Welsh surveyor who worked as the British Surveyor General of India from 1830 to 1843. The height of Mount Everest was first published in 1856, when it was known as Peak XVI. In 1953 the first successful ascent to the summit of Mount Everest was achieved by New Zealander Edmund Hillary and Nepali sherpa Tenzing Norgay. From 2005 - 2010 there was an argument about the exact height. China claimed that it should be measured based on the height of bare rocks which stood at is 8,844m. While, Nepal claimed that the height of Mount Everest should be measured based on the height of snow, which stood at 8,848m. Finally an agreement was reached between two countries saying that height of Mount Everest is 8,848m.
In the year 1802, the British began to
conduct survey on India to know the locations and the names of the highest peaks. The survey was called as Great Indian Trigonometric
Survey. In the year 1847, Andrew Waugh,
a British surveyor, made many survey and finally concluded that Kanchenjunga
was the highest peak of Himalayas. However in the year 1852, an Indian
mathematician/ surveyor by name Radhanath Sikdar from Bengal identified Everest
as the highest peak by using trigonometric calculations.
The geology of Mount Everest is very simple. The mountain consists of sedimentary rocks that were under Tethys Sea. The sedimentary rock layers of Mount Everest are limestone, marble, shale, and pelite underneath them are older rocks including granite, pegmatite intrusions, and gneiss. Mount Everest is composed of three distinct rock formations. Each formation is separated by faults called as detachments. From the mountain base to the summit one can notice the Rongbuk Formation, the North Col Formation and the Qomolangma Formation.
Base formation of Mount Everest is Rongbuk Formation. This formation is made up of rocks like schist and gneiss with numerous sills and dikes. These rocks are high grade meta-sedimentary rocks. In short this formation acts as the foundation of Himalayas and extend up from mean sea level to about 7,000m above mean sea level.
The North Col Formation is located between 7,000m and 8,600m above mean sea level. The upper 400 meters forms the famous ‘Yellow Band’, a yellowish brown rock band of marble, phyllite with muscovite and biotite and semischist, a slightly metamorphosed sedimentary rock. The band also contains fossils of crinoid ossicles, a marine organism with a skeleton. Below the Yellow Band are more alternating layers of marble, schist, and phyllite. The lower 600 meters is composed of various schist formed by metamorphism of limestone, sandstone, and mudstone. At the bottom of the formation is the Lhotse detachment, a thrust fault that divides the North Col Formation from the underlying Rongbuk Formation.
The Qomolangma Formation, the
highest rocks on the summit pyramid of Mount Everest, is formed by layers of ordovician-age
limestone dolomite, siltstone, and laminae. The formation starts at 8,600m at a
fault zone above the North Col Formation and ends on the summit. The upper
layers have many marine fossils, including trilobites, crinoids, and ostracods. Mount Everest is
like a triangular pyramid shape. The
flat planes on the three sides are called as faces and the line by which the
two faces join is called as ridge.
In the lower forested zone, birch, juniper, blue pines, firs, bamboo and rhododendron grow. Above this zone all vegetation are shrubs. As the altitude increases, plant life is restricted only to lichens and mosses above 5,750m plant life ceases as it is completely covered by snow throughout the year. The Sagarmatha National Park is one of the most beautiful places, especially in summer. After the first monsoon rains in June, different kinds of plant grow rapidly. The hillsides become green and different varieties of flowers start blooming, and butterflies of myriad species appear in different colors. Due to the presence of insects in the environment, many kinds of birds are also seen in the National Park. 118 species of birds and 26 species of butterflies have made this park their home.
Some of the endangered animals
that are found in this park are musk deer, wild yak, red panda, snow leopard
and Himalayan black bear. Besides, many other animals such as Himalayan thars,
deer, langur monkeys, hares, mountain foxes, martens, and Himalayan wolves are
found in the park.
There are two main routes to climb Mount Everest. One of the routes is Southeast ridge route from Nepal and another is North ridge route from Tibet. Apart from these two routes there are numerous routes which are less frequently used. Of these two main routes, the Southeast ridge is technically easier to ascent. Edmund Hillary and Tenzing Norway climbed the Mount Everest from this route as the other route was not accessible to westerns as China had invaded Tibet in 1950’s.
Climb through Southeast ridge
The ascent from the Southeast ridge start from the base camp at 5,380m which is on the southern side of the Everest. Climbers are made to spend few weeks in the base camp to get acclimatized to the altitude. During this period some of the experienced sherpas and few other climbers set up ropes and ladders for further trek. The climb from base camp at 5,380m involves following steps:
Climb through North ridge
The North ridge base camp begins from the Northern side of Everest in Tibet. This route is less popular compared to South-Eastern ridge route. Climb in this route involves following steps:
Climbers go for the final summit push in ‘three steps’. Any climber who wants to climb the Mount Everest from this ridge must deal with these three steps. The altitudes of these 3 steps are 8,564 m, 8,610m and 8,710m. The second step is very important in terms of history and mountaineering. The First Step consists of big and huge boulders which causes a serious threat even for experienced climbers. The Second Step is the best known as the rocky steps. In the second step a climber has to climb at least the last five step vertically due to its steep angle. The step was climbed for the first time in 1960 by Wang Fuzhou, Gongbu, and Qu Yinhua. The climbing difficulty of this spot was reduced in 1975 when a Chinese team fixed a ladder to these steps which is now used by all the climbers. The third step is easier to climb. After climbing for 10m summit snow field is reached.
Logistics for the climb
Mount Everest climb would at least
require two – three months. Overall cost may be upto USD 60,000. It may vary slight depending on the route
taken. The South ridge route is slightly
more expensive compared to North ridge route.
The guides (famously known as Sherpas) take care of food, fuel and other
requirements needed during the ascent. They also help in getting the permits
required for climbing.
1. Permits: Obtaining permits from the respective governments is mandatory. Depending on the route chosen the permits have to be obtained either from Nepal or Tibet Government.
2. Cost involved: Overall cost may be upto USD 60,000. It may vary slight depending on the route taken. The South ridge route is slightly more expensive compared to North ridge route. Following are covered in this overall cost:
