Karakoram, or Tsung Ling Mountains, a division of the Himalayas extending from the Hindoo Koosh in the west along the boundary of Cashmere into Tibet on the east. The range in general varies in height from 18,000 feet to 25,000 feet, but the peak known as K2 is over 28,000 feet high. The Karskoram Pass, almost in the centre of the chain, and the head of the Shayok Valley, is about 18,500 feet high. It was found by Dr. Thomson, who ascended it in 1848, to be quite free from snow. The old capital of Mongolia, ruins of which remain, also has this name.
