Location and geology
The cold deserts of Leh formed as a result of several factors, including its high altitude, low precipitation, and arid climate.Leh is situated at an elevation of over 11,000 feet above sea level in the Himalayan mountain range, which exposes it to harsh and cold winds. The region is located in a rain shadow area, meaning that the mountains block most of the moisture-laden winds from reaching the area, resulting in low levels of precipitation.
Furthermore, the region’s location on the leeward side of the mountain range also means that it is protected from the monsoon winds, which are the main source of rainfall in many parts of India. This combination of high altitude, low precipitation, and arid conditions creates a unique environment that is inhospitable to most forms of plant and animal life, leading to the formation of the cold deserts of Leh.
Leh is a region in the northernmost part of India, known for its cold deserts. The area experiences harsh winters with temperatures dropping below freezing and very little rainfall, making it inhospitable for most forms of plant and animal life. Leh is located in the northern Indian state of Jammu and Kashmir and is part of the larger Ladakh region. It is situated in the Himalayan mountain range and is known for its high-altitude cold deserts. Despite this, the region is home to several unique and hardy species, as well as various nomadic communities who have adapted to the harsh conditions.

The cold deserts of Himachal Pradesh are located in the northwestern part of India and cover the Spiti and Ladakh regions which cover an area of approximately 13,835 square kilometers.. The region is situated at high altitudes, ranging from about 12,000 to 22,000 feet above sea level, and is surrounded by mountain ranges, including the Himalayas.
The cold deserts in Himachal Pradesh were formed due to a combination of geological and climatic factors. Geologically, the region is located in the rain shadow of the Himalayas, meaning that the high mountains block the monsoon winds and prevent them from reaching the region, resulting in very low precipitation levels. Climatically, the region is influenced by the Siberian anticyclone, which brings cold, dry air from the north that contributes to the arid conditions in the region. In addition, the high altitude of the region also plays a role in creating cold desert conditions, as the thin atmosphere results in low temperatures even in the summer months. These factors combined have created the unique cold desert landscape in Himachal Pradesh.
There are several lakes and dams located in the cold desert region of Himachal Pradesh. Chandra Tal is a high-altitude lake situated in the Spiti Valley, known for its stunning turquoise blue waters and picturesque surroundings.
Suraj Tal is another high-altitude lake located near the Baralacha Pass, known for its breathtaking views and peaceful surroundings.
