Himalayas
mountain range in Asia
The Himalayas are a range of mountains in Asia. The Himalaya proper stretches from the Indus River in Pakistan, through India, Nepal, and Bhutan, and ends at the Brahmaputra River in eastern India.
The Greater Himalaya complex of mountains includes the Himalayas and some related ranges. On the eastern end, the Hengduan Range — which includes the Three parallel rivers, a UNESCO World Heritage Site in China — forms a T shape with that end of the Himalayas.
On the west, the Himalayas connect to a large area of high ground called the Pamir Knot, also a UNESCO World Heritage Site. Several other ranges extend in various directions from the knot — the Karakoram, running east parallel to the Himalaya and north of it, the Hindu Kush running southwest into Afghanistan, the Tian Shan Range running north, and the Kunlun Range northeast. All those ranges, and the Pamir Knot, include peaks over 7000 m. All except Tian Shan can be seen in the photo to the right.
The Himalayas region of Nepal has eight of the world's ten tallest mountains including the highest of all, Mount Everest at 8849 m. The Karakoram Range has four peaks over 8000 m including the world's second highest mountain, K2 at 8611 m. It also has the highest unclimbed mountain (as of late 2020) where climbing is not forbidden, Muchu Chhish at 7542 m.
For comparison, neither Western Europe nor the lower 48 US states have anything that reaches 5,000 m. In the Himalayan region, several of the passes are around 5000, and some nomads spend the summer at about that altitude every year so their herds can graze the upland meadows. Mount Elbrus is Europe's highest peak and Mount Kilimanjaro is Africa's; both are slightly under 6000 m. On the climbers' list of Seven Summits, the highest mountains on each continent, only two besides Everest are over 6000 — Denali in Alaska at just under 6200, and Aconcagua, the highest peak of the Andes and the tallest mountain outside the Greater Himalayan region, at just under 7000.
In the Himalayas, peaks over 6000 m are commonplace and there are dozens over 7000. Wikipedia's list of the highest mountains in the world has 109 mountains, all in the greater Himalaya region, all over 7200 m (23,622 feet) and including 14 over 8000 m.
