However, when government documents, scientific studies, and official information are considered together, the picture becomes clearer and more scientific. Chorabari Glacier is an important part of the source system of the Mandakini River, while the meltwater stream emerging from the Companion Glacier is known as the Saraswati, which later joins the Mandakini. Chorabari Lake was a moraine-dammed lake, and on 17 June 2013, its outburst contributed to the devastating flooding in the Kedarnath region.
Where is Chorabari Glacier located ?
Kedarnath, located in Uttarakhand's Rudraprayag district, lies at an elevation of approximately 3,580 metres. According to the Uttarakhand Tourism Department, Kedarnath is situated near the Chorabari Glacier, which is connected to the source region of the Mandakini River. Chorabari Lake, also known as Gandhi Sarovar, was located in the same area.
According to scientific research, Chorabari Glacier is a medium-sized compound valley glacier. One study has estimated its area at approximately 6.6 square kilometres. It is located within the Mandakini River basin, with its glacial zone extending through the high-altitude Himalayan terrain.
Therefore, showing Chorabari Glacier above Kedarnath in a viral map can help explain the general geographical relationship. However, such an image should not be treated as an accurate survey map. The blue outlines, distances and sizes shown in such graphics may not represent the actual scale of the landscape.
What is the Companion Glacier ?
The second glacier shown alongside Chorabari Glacier in these images and labelled “Companion Glacier” is a real geographical feature. Scientific research also identifies it as the Companion Glacier.
According to a 2023 study, the Companion Glacier is a smaller glacier located close to Chorabari Glacier. Its area was estimated at approximately 2.11 ± 0.1 square kilometres in 2020. The meltwater stream originating from this glacier is known as the Saraswati. The stream flows for roughly 1.5 kilometres downstream before joining the Mandakini River.
A document associated with the Geological Survey of India (GSI) also describes the drainage system associated with the Chorabari and Companion Glacier areas. The Saraswati stream descends from the Companion Glacier and joins the Mandakini approximately 500 metres downstream of Kedarnath.
Therefore, showing the Chorabari Glacier and Companion Glacier as separate glaciers in the image is broadly consistent with the geography. However, it would not be accurate to treat them as the same glacier or to describe both as equal primary sources of the Mandakini River.
What was Chorabari Lake or Gandhi Sarovar ?
Located below the Chorabari Glacier, Chorabari Tal is also known as Gandhi Sarovar. The Uttarakhand Tourism Department describes it as a water body located near the glacier. It came to be known as Gandhi Sarovar after a portion of Mahatma Gandhi's ashes was immersed here in 1948.
The lake was not an ordinary lake formed like a large river-fed reservoir. Rather, water accumulated behind a natural barrier made of glacial debris known as a moraine. Such a lake is referred to as a moraine-dammed lake. Documents associated with the Wadia Institute of Himalayan Geology also describe Chorabari Lake as a moraine-dammed lake.
What happened on 17 June 2013 ?
It would be scientifically incomplete to describe the Kedarnath disaster simply by saying, “The glacier broke and a flood occurred.”
According to the Government of India's Press Information Bureau, Uttarakhand experienced exceptionally heavy and early rainfall in June 2013. Between 14 and 18 June, several areas received extremely heavy rainfall. Processes including snowmelt at higher elevations and the failure of water bodies contributed to a rapid rise in river levels.
According to Central Water Commission documents, Chorabari Lake experienced an outburst on the morning of 17 June 2013, and the lake drained within less than approximately 15 minutes. At the time, the lake was located at an elevation of around 3,960 metres and approximately 2.1 kilometres upstream of the Kedarnath temple complex.
Hydrological modelling estimated the peak flood discharge near the lake at approximately 1,273 cubic metres per second, while the estimated flow near the Kedarnath temple area was around 1,200 cubic metres per second.
A report from the Wadia Institute of Himalayan Geology also states that the outburst of Chorabari Lake on 17 June released a large volume of water, triggering a sudden flood in Kedarnath and causing extensive destruction downstream.
However, it is important to understand that the entire 2013 disaster cannot be attributed solely to the lake outburst. Government disaster reports and scientific studies have discussed the roles of extremely heavy rainfall, sudden water discharge, debris, glacial processes and other drainage channels. Therefore, saying that “the entire Kedarnath disaster happened only because Chorabari Lake burst” would be an oversimplification.
Is Chorabari Glacier still retreating rapidly ?
This issue also requires caution.
The Government of India's Ministry of Earth Sciences has reported that glaciers across the Himalayas are melting and retreating at different rates. According to the same government information, Chorabari Glacier recorded an average retreat rate of approximately 9–11 metres per year between 2003 and 2017.
However, this does not mean that the glacier's appearance in a viral image necessarily represents its actual condition in 2026. Determining the current state of a glacier requires comparison of satellite imagery from different years, field measurements and mass-balance studies.
Scientific studies have also reported that the lower part of Chorabari Glacier contains a substantial debris cover and that the glacier has undergone significant changes over time.
Could a similar flood happen again in the future ?
Glacial lakes, heavy rainfall, avalanches, landslides and other natural processes can create genuine hazards in the Himalayan region. The Government of India has also highlighted the need for monitoring and scientific assessment of glacial lake hazards and Glacial Lake Outburst Floods (GLOFs) in the Himalayan region.
However, this does not mean that another flood identical to the 2013 disaster will occur in Kedarnath on a particular date. Such a prediction cannot be made from the available evidence.
Actual risk assessment depends on several factors, including weather conditions, lake size, water level, moraine stability, glacier conditions and real-time monitoring.
The basic geographical relationship shown in the viral images is broadly real: Chorabari Glacier, the nearby Companion Glacier, the area of Chorabari Lake, Kedarnath and the Mandakini River system are all located within the same broader Himalayan region. The Saraswati stream originating from the Companion Glacier eventually joins the Mandakini River.
The most important fact is that on 17 June 2013, the failure of the moraine-dammed Chorabari Lake released a large volume of water and contributed to the devastating flooding in Kedarnath. However, describing the entire 2013 disaster simply as a “glacier collapse” or solely as a “lake outburst” would not be scientifically accurate. Extremely heavy rainfall and other Himalayan processes also played important roles.
Therefore, these viral images are better understood as illustrative visuals explaining the geography, rather than as precise satellite maps showing the current situation or as predictions of future flooding.
Based on the available official information and scientific research, this is the most cautious and fact-based interpretation of the relationship between Kedarnath, Chorabari Glacier, Companion Glacier, Chorabari Lake and the Mandakini River, as well as their connection to the devastating events of June 2013.
