Ladakh Geographical Background
Ladakh is sandwiched between two vast mountain systems, the Karakoram to the north and the Himalaya to the south. Covering an area of about 60,000 sq km and ranging in elevation from 2600m to 7070 m, it is the largest and highest district in India. The Indus valley is the Ladakhi heartland, with the highest population density, and large amounts of agricultural land. Running parallel, roughly north-east south-west with it are a series of valleys and mountain ranges. North of the Indus valley is the Ladakh range, on the other side of which is the Shayok, and Nubra valleys. South of the Indus is the Stok range, clearly visible from Leh. On the other side is the Markha valley, a popular trekking destination. Farther south-west is a series of minor ranges and then uninhabited valleys we come to Zangskar, with the Kargyak and the Stod rivers joining at Padum, to form the Zangskar river which bucks the trend and flows north through a narrow gorge to join the Indus. To the south of Zangskar is the Grand Himalayan range marking the southern limit of Ladakh. To the east of this series of ranges is the Changtang, a high plateau home to nomads. It is known as Kharnak in the west, Samad Rokchen in the north east and Korzok in the south east. Not a true plateau, it has a chaotic assortment of minor mountains ranges not much higher than the wide valleys between them. With no drainage leading out of this area, there are a number of beautiful salt water lakes that make popular destinations for tourists.
