Glaciers in India are bodies of dense ice that flow under their own weight.
They are formed as a result of snow accumulation, which compresses them into a denser ice mass. India has a vast number of glaciers.
According to the Space Applications Centre of the Indian Space Research Organization (ISRO), India has 16,627 glaciers. The Himalayan region, in particular, boasts some of the world’s most prominent glaciers.
Glaciers
Glaciers are masses of ice that move under their own weight. It originates in regions where snow accumulation exceeds ablation over many years. They are sensitive markers of climate change.
They are commonly observed in snow fields. This greatest freshwater basin encompasses over 10% of the Earth’s land surface. Glaciers contain 2.1% of all water on Earth, while the oceans and inland seas contain 97.2%.
Condition of glacier formation
- The average annual temperature is close to freezing.
- Winter precipitation causes significant snow accumulations.
- Temperatures during the remainder of the year do not result in the entire removal of snow accumulation from the previous winter.
- Temperatures during the remainder of the year do not result in the entire removal of snow accumulation from the previous winter.
- The glacier can be classified as a Mountain Glacier (Alpine Glacier) or a Continental Glacier based on its topography and position (Ice Sheets).
- The Mountain Glacier goes from a higher to a lower height, whereas the Continental Glacier flows in all directions.
Alpine Glaciers
- Alpine glaciers occur on steep slopes and usually travel southward via valleys.
- An alpine glacier can sometimes deepen valleys by pushing away debris, soil, and other things.
- These glaciers can be found in the highest elevations.
Ice sheets
- Ice sheets typically create huge domes that extend out in all directions.
- When ice sheets spread, they cover all areas with a thick layer of ice, including valleys, plains, and mountains.
- The continental glaciers are the largest ice sheets, covering most of Antarctica and the Greenland islands.
Glaciers in India
The majority of glaciers on the Indian map may be found in Himachal Pradesh, Sikkim, Uttarakhand, and the Union Territory of Ladakh. Arunachal Pradesh has a few glaciers as well. Some of India’s glaciers are as small as football fields, while others stretch for hundreds of kilometres.

Himalayan glaciers
The Himalayas have around 15,000 glaciers. The Himalayas cover an area of around five lakh square kilometers (the Area of India is nearly 32 lakh sq km). Snow has blanketed an area of around 33,000 square kilometers.
The snow line (the lowest level of perpetual snow) varies across the Himalayas based on latitude, precipitation, and topography.
- The Karakoram Range’s glaciers: The Karakoram range has the most glacier development.
This range has some of the greatest glaciers found outside of the polar and sub-polar areas. Several massive glaciers can be seen on the range’s southern flank. The 75-kilometer-long Siachen Glacier in Nubra Valley is the world’s second-largest glacier outside of the polar and sub-polar areas. The Fedchenko Glacier (Pamirs) is the largest, measuring 77 kilometers in length. The Hispar Glacier is the third largest. It is 62 kilometers long and is located on a branch of the Hunza River. - Glaciers of the Pir Panjal Range: The glaciers of the Pir Panjal Range are fewer and smaller in size than those of the Karakoram Range. The longest Sonapani Glacier in the Lahul and Spiti region is only 15 kilometers long.
- Kumaon-Garhwal Region Glaciers: The Gangotri Glacier, which is the source of the holy Ganga, is the largest in the Kumaon-Garhwal area of the Himalayas.
- Glaciers of Central Nepal: The major glaciers in Central Nepal are the Zemu and Kanchenjunga glaciers.
Major Glaciers in India
Major Glaciers in India like Gangotri Glacier, Siachen Glacier, Hispar, etc. are discussed below.
Gangotri Glacier
- Uttarakhand’s largest glacier.
- The Ganges’ headwaters (Bhagirathi River)
- The Gangotri glacier flows from the northern slope of the Chaukhamba group of peaks in the Garhwal Himalayas.
- Gangotri is a conglomeration of glaciers rather than a single valley glacier.
Siachen Glacier
- Siachen Glacier, located in the Nubra Valley above the Karakoram Mountains, is the second largest glacier outside of the polar and sub-polar areas.
- Its primary tributaries are Lolofond and Teram Shehr.
- India and Pakistan are at odds.
Hispar
- The Hunza River is a tributary of the third-largest glacier in the Karakoram area.
- Combines with Biafo Glacier to cover approximately 65 square kilometers of Braldoh Valley.
- Kunyong/Lak (24 km) is a significant Hispar tributary.
Biafo
- The Braldoh Valley’s fourth largest glacier is located between the Hispar and Baltoro glaciers.
- Occupies the Gori Ganga River valley, which was formed by the convergence of nine glaciers.
Pindari
- Pindari is a 90-kilometer round-trip walk located to the south of the Nanda Devi in northeast Uttarakhand. It is the source of the
- Pindar River is located in the upper ranges of the Kumaon Mountains.
Zemu
- At the head of the Zemu River, Zemu flows eastward.
- The Eastern Himalayas’ largest glacier is approximately one kilometer broad and 180 meters thick (26 km)
- Located near the foot of Kanchanjunga
- One of the Teesta River’s putative sources
Baltoro
Baltoro is a 65-kilometer-long glacier in the Karakoram range, west of the Siachen glacier, that gives rise to the Shigar River, a tributary of the Indus.
Bara Shigri Glacier
- This glacier, which feeds the Chandra River in Himachal Pradesh’s Lahaul and Spiti valleys, is the third largest in India.
- It currently stretches across 27.7 kilometers and spans an area of 126.45 square kilometers. The glacier’s highest point is 6363 meters.
- Bara Shigri feeds the Chandra River, which becomes Chandrabhaga or Chenab after meeting the Bhaga River at Tandi.
Drang-Drung Glacier
- This mountain glacier, also known as Drung Glacier, is India’s fifth tallest. It is located in the Kargil area of Ladakh.
- The glacier’s longest length is 23 kilometers, with an average elevation of 4,780 meters.
- The Drang-Drung Glacier is a long ice river that feeds the Stod River, which is a tributary of the Zanskar River, which is a tributary of the Indus River.
- The glacier is located in the Zanskar Range of the Himalayas, south of Kargil and east of Srinagar, the state capital of Jammu and Kashmir.
The Milam Glacier
- It is the longest glacier in the Uttarakhand tehsil of Munsiyari, Pithoragarh district, around 15 kilometers northeast of Nanda Devi.

Conclusion
The glacier, like others, has been melting at alarming rates as a result of global warming. The glaciers serve as proxies for global warming and climate change.
The Himalayan glaciers in India also serve as key freshwater supplies for the country’s northern reservoirs and rivers. That is why glacier monitoring is critical.
