      <p>Mount Everest, known in Nepali as Sagarmāthā and in Tibetan as Chomolungma, is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The international border between China (Tibet Autonomous Region) and Nepal (Province No. 1) runs across its summit point.</p>
      <p>The current official elevation of 8,848 m (29,029 ft), recognised by China and Nepal, was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975.[1] In 2005, China remeasured the rock height of the mountain, with a result of 8844.43 m.</p>

      <p>K2 is known as the Savage Mountain due to the extreme difficulty of ascent. It has the second-highest fatality rate among the eight thousanders. With around 300 successful summits and 77 fatalities, about one person dies on the mountain for every four who reach the summit.</p>
      <p>It is more difficult and hazardous to reach the peak of K2 from the Chinese side, so it is usually climbed from the Pakistani side. Unlike Annapurna, the mountain with the highest fatality-to-summit rate (191 summits and 61 fatalities), or the other eight thousanders, K2 has never been climbed during winter.</p>

      <p>Mount Kangchenjunga lies about 125 km (78 mi) east-south-east of Mount Everest. It is the second highest mountain of the Himalayas. Three of the five peaks – Main, Central and South – are on the border between North Sikkim and Nepal. Two peaks are in Nepal's Taplejung District.</p>
      <p>Kangchenjunga Main is the highest mountain in India, and the easternmost of the mountains higher than 8,000 m (26,000 ft). It is called Five Treasures of Snow after its five high peaks, and has always been worshipped by the people of Darjeeling and Sikkim.</p>
