The Himalayan range, topped by 29,035-foot Mount Everest, the tallest mountain in the world, is one of the largest and most distinct geographic features on the earth’s surface. This majestic range, running northwest to southeast, stretches 1,400 miles and varies in width between 140 miles and 200 miles. It crosses or abuts five different countries—India, Nepal, Pakistan, Bhutan, and the People’s Republic of China—serving as the origin for three major rivers: the Indus, Ganges, and Tsampo-Bramhaputra. Moreover, it boasts over 100 mountains that soar beyond 23,600 feet.
