Important Glaciers in India – UPSC

In this article, You will read (Ultimate list of) Important Glaciers in India – for UPSC IAS.

Glacier

Glaciers are a bulk of ice moving under its weight. It forms in areas where the amassing of snow goes beyond its ablation over many years. They are sensitive indicators of changing climate.

  • They are generally seen in the snow-fields. 
  • This largest freshwater basin covers around 10 percent of the land surface of the Earth.
  • Out of total water on Earth2.1% is in glaciers while 97.2% is in the oceans and inland seas.
  • Condition of glacier formation:
    • Mean annual temperatures are close to the freezing point.
    • Winter precipitation produces significant accumulations of snow.
    • Temperatures throughout the rest of the year do not result in the complete loss of the previous winter’s snow accumulation.
  • According to the topography and the location of the glacier, it can be categorized as Mountain Glacier (Alpine Glaciers) or Continental Glacier (Ice Sheets).  
  • The Continental Glacier moves outward in all directions whereas the Mountain Glacier moves from a higher to a lower altitude.

Alpine Glaciers

  • Alpine glaciers are formed on the mountainsides and they usually move downwards through the valleys. 
  • There are times when an alpine glacier also deepens the valleys by pushing away the dirt, soil, and other materials.  
  • These glaciers are found in high mountains.

Ice Sheets

  • Ice sheets form broad domes and usually spread out in all directions.
  • When the ice sheets spread, they cover all the areas such as valleys, plains, and mountains with a thick blanket of ice. 
  • The continental glaciers are the largest ice sheets and cover most of Antarctica and islands of Greenland.
Geographical Location of Glaciers
  • 91% of the Glaciers are in Antarctica and 8% are in Greenland. They occupy about 10% of the world’s total land area.

Glaciers in Himalayas

  • There are about 15,000 glaciers in the Himalayas.
  • Total area of Himalayas is about five lakh square kilometres (Area of India is nearly 32 lakh sq km). About 33,000 sq km area is covered by snow.
  • The snow line (the lowest level of perpetual snow) varies in different parts of the Himalayas depending upon latitude, amount of precipitation and local topography.

Glaciers of the Karakoram Range

  • Maximum development of glaciers occurs in the Karakoram range.
  • Some of the largest glaciers outside the polar and sub-polar regions are found in this range. The southern side of this range has many gigantic glaciers.
  • The 75 km long Siachen Glacier in Nubra valley has the distinction of being the largest glacier outside the polar and the sub-polar regions.
  • The second largest is the 74 km long Fedchenko Glacier (Pamirs)
  • Third largest is the Hispar Glacier. It is 62 km long and occupies a tributary of the Hunza River.

Glaciers of the Pir Panjal Range

  • The glaciers of the Pir Panjal Range are less numerous and smaller in size as compared to those of the Karakoram Range.
  • The longest Sonapani Glacier in the Chandra Valley of Lahul and Spiti region is only 15 km long.

Glaciers of the Kumaon-Garhwal Region

  • In the Kumaon-Garhwal region of the Himalayas, the largest is the 30 km long Gangotri Glacier which is the source of the holy Ganga.
Garhwal Region
  • Lying in the Himalayas, it is bounded on the north by Tibet, on the east by Kumaon region, on the south by Uttar Pradesh state, and on the northwest by Himachal Pradesh state.
  • It includes the districts of Chamoli, Dehradun, Haridwar, Pauri Garhwal, Rudraprayag, Tehri Garhwal, and Uttarkashi.

Glaciers of Central Nepal

  • Zemu and the Kanchenjunga glaciers are the major ones.

Gangotri Glacier

  • Largest Glacier in Uttarakhand.
  • Source of the Ganges. (River Bhagirathi)
  • The Gangotri glacier originates at the northern slope of Chaukhamba range of peaks in Garhwal Himalayas.
  • Gangotri is not a single valley glacier, but a combination of several other glaciers.
  • Carbon Deposits on Gangotri
    • The Wadia Institute of Himalayan Geology is an Autonomous Institute administered by the Department of Science and Technology. 
    • They have the Chirbasa station at a height of 3,600 m and Bhojbasa station at a height of 3,800 m.
    • They research the number of carbon deposits on the important glaciers of the Himalayas. Gangotri being the source of the Ganges is one of the most important Glaciers in the country. 
    • According to recent data from the research, the concentration of Black Carbon present on the Gangotri Glacier has doubled when compared to the results of the past few years.
    • The primary reason for this is the agricultural burning and forest fires in the nearby regions.
