63-699: Is still often referred to as Tsomo Nganglha Ringpo ( Tibetan : མཚོ་མོ་ངང་ལྷ་རིང་པོ ) in Tibetan. There are different interpretations of the meanings of both Pangong Tso and Tsomo Nganglha Ringpo . The Ladakh government website says "Pangong Tso" is Tibetan, meaning "high grassland lake", however travel books say Pangong means "hollow". Tsomo Nganglha Ringpo is Tibetan that is interpreted to mean various different but similar meanings -- "long, narrow, enchanted lake" by Chinese media sources, "female narrow very long lake" by early European explorers, and "long-necked swan lake" by other modern sources. Pangong Tso
84-472: Is surrounded by three mountain ranges: Changchenmo Range and Pangong Range sub-ranges of Karakoram Range , and Kailash Range (Gangdise Shan range). Changchenmo Range runs along the eastern and northern bank of the Pangong Tso, and contains spurs Finger-1 to Finger-8. Pangong Range , along the southern bank of the Pangong Tso, runs from Tangtse in west to Chushul near the centre of southern bank of

126-770: The fingers . From west to east, these are named as the Finger-1 to Finger-8 . The Indian claim of LAC runs east till the Finger-8, and the Chinese claim of the LAC runs west till the Finger-4. The overlapping LAC claim area between Finger-4 and Finger-8 is considered a buffer zone by India and China. Indian Military has a permanent base near the Finger-3, named as the Dhan Singh Thapa Post , and
147-507: The Indian side of the lake, except for some small crustaceans . On the other hand, visitors see numerous ducks and gulls over and on the lake surface. There are some species of scrub and perennial herbs that grow in the marshes around the lake. The lake acts as an important breeding ground for a variety of birds including a number of migratory birds. During summer, the bar-headed geese and Brahmini ducks are commonly seen here. The region around
168-632: The Khurnak Fort by 1958. On 20 October 1962, Pangong Tso saw military action during the Sino-Indian War , successful for the Chinese People's Liberation Army (PLA). The area remains a sensitive border point along the LAC. Incursions from the Chinese side are common. In August 2017, Indian and Chinese forces near Pangong Tso engaged in a melee involving kicking, punching, rock throwing, and use of makeshift weapons such as sticks and rods. On 11 September 2019, PLA troops confronted Indian troops on
189-499: The LAC and overlook Chinese camps. India chose to pull back from these positions as leverage for larger disengagement. Both the Chinese and Indian militaries have vessels stationed on the lake. Since 2022, China built a bridge across the lake near the Khurnak Fort. The construction of the 400-meter bridge was completed in July 2024. Following roads provide the access within the Indian held area: Following roads provide
210-563: The Pangong Tso. According to the Britannica , the Changchenmo Range and Pangong Range are sometimes considered easternmost part of the Karakoram Range . Kailash Range , runs along southern bank of the Pangong Tso, from centre of Pangong Tso at Lukung to the west to Phursook Bay and Mount Kailash . Changchenmo Range has several glaciated spurs which slope down and jut into the northern bank of Pangong Tso, and these spurs are called as
231-607: The access within the China held area: On the Indian side, an Inner Line Permit is required to visit the lake, as it lies on the Sino-Indian Line of Actual Control . For security reasons, India does not permit boating. Groups are permitted, accompanied by an accredited guide. The past few years have seen a remarkable increase in Indian tourists flocking to Pangong Lake. However, this surge has presented environmental challenges due to inadequate infrastructure to accommodate and manage

Pangong Tso is disputed territory. The Line of Actual Control (LAC) passes through
273-494: The growing number of visitors. In 2023, on the Indian side the tourists are allowed to visit only the eastern and southern bank, access to the north bank is not yet open for the tourists. The eastern part of the lake is fresh, with the content of total dissolved solids at 0.68 g/L, while the western part of the lake is saline, with the salinity at 11.02 g/L. The brackish water of the lake has very low micro-vegetation. Guides report that there are no fish or other aquatic life on
294-655: The lake from the Indian side, forming marshes and wetlands at the edges. Strand lines above current lake level reveal a 5 m (16 ft) thick layer of mud and laminated sand, suggesting the lake has shrunken recently on the geological scale. On the Indian side, no fish have been observed, however in the stream coming from the south-eastern side (Cheshul nalla), three fish species ( Schizopygopsis stoliczkae , Tibetan stone loach and Triplophysa gracilis ) have been reported (Bhat et al., 2011). The low biodiversity has been reported as being due to high salinity and harsh environmental conditions (Bhat et al., 2011). Bird Islet
315-448: The lake is viewed as being made up five sublakes, which are connected through narrow water channels. The name Pangong Tso only applied to the westernmost lake that is mostly in Ladakh. The main lake on the Tibetan side is called Tso Nyak (the "middle lake"). It is followed by two small lakes called Rum Tso . The last lake near Rutog is called Nyak Tso again. The whole lake group was and
336-521: The lake supports a number of species of wildlife including the kiang and the marmot . The lake hosts large quantities of fish, especially Schizopygopsis stoliczkai and Racoma labiata . Freshwater snails of the genus Radix also live in the lake. Formerly, Pangong Tso had an outlet to the Shyok River , a tributary of the Indus River , but it was closed off by natural damming. Two streams feed

The eastern end of the lake is in Tibet . After the mid-19th century, Pangong Tso was at the southern end of Johnson Line , an early attempt at demarcation between India and China in the Aksai Chin region. Khurnak Fort lies on
378-638: The left of the Sirijap plain at a shore point called "Finger 8". China claims the LAC to be further west at "Finger 4". The area between the two fingers continues to be patrolled by the Indian border police . In May 2013, it was report that China had constructed a metal-top road in the area leading up to Finger 4. The Indian army claims to have used the road to patrol the area.

399-540: The northern bank of the lake, about halfway up Pangong Tso. The dispute over the fort was discussed in a 1924 conference, which remained inconclusive. After the conference, the British government decided that Tibetans had a better case and not only Khurnak Fort but also Dokpo Karpo and Nyagzu were part of Tibet. In 1929, following the protests of Kashmir Durbar, they decided to drop the British claims made in behalf of Kashmir state. The Chinese established their military presence in
420-402: The northern bank. On 5–6 May 2020, a face-off between about 250 Indian and Chinese troops near the lake resulted in casualties on both sides. On 29–30 August 2020, Indian troops occupied many heights on the south bank of Pangong Tso. The heights included Rezang La , Reqin La, Black Top, Hanan, Helmet, Gurung Hill , Gorkha Hill and Magar Hill. Some of these heights are in the grey zone of
441-445: The remaining 10% is disputed and is a de facto buffer zone between India and China. The lake is 5 km (3.1 mi) wide at its broadest point. All together it covers almost 700 km . During winter the lake freezes completely, despite being saline water . It has a land-locked basin separated from the Indus River basin by a small elevated ridge, but is believed to have been part of the latter in prehistoric times. Historically,
