The Great Himalayas (also known as Greater Himalayas or Himadri) is one of the four parallel sub-ranges of the Himalayas.[1][2] It is the highest in altitude and extends for about 2,300 km (1,400 mi) from northern Pakistan to the Indian state of Arunachal Pradesh, passing through China, Nepal, and Bhutan. The sub-range has an average elevation of 6,100 m (20,000 ft) and contains many of the world’s tallest peaks including the eight-thousanders and Mount Everest, the highest peak on Earth.[3][4] The range is mainly composed of granite rocks with permafrost and consists of many glaciers including Gangotri, Khumbu, and Satopanth Glaciers.[5][6]
