Imja Tsho
Imja Tsho (or Imja Lake) is a glacial lake created after melt water began collecting at the foot of the Imja Glacier on the lower part of the glacier in the 1950s. A 2009 study described this lake of melt water as one of the fastest-growing in the Himalaya. Held in place by a terminal moraine, Imja Tsho threatens downstream communities with the potential for a glacial outburst flood. Imja Tsho has been identified as one of the potentially dangerous lakes in Himalaya. It is located at 27° 53' 55" N latitude, 86° 55' 20" E longitude and at an altitude of 5010 m in Everest region of Nepal. The catchment of Imja Tsho occupies the northeastern part of the Dudh Koshi sub-basin. The lake itself is located on the lower part of the glacier at the toe of its mother glaciers (snout of Imja and Lhotse Shar Glaciers). The Lhotse Shar Glacier flows in a south-westerly direction. The Imja Glacier on the other hand is oriented in a north-westerly direction and has its terminus at about 5100 m. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepal
Nepal (; ne, नेपाल ), formerly the Federal Democratic Republic of Nepal ( ne, सङ्घीय लोकतान्त्रिक गणतन्त्र नेपाल ), is a landlocked country in South Asia. It is mainly situated in the Himalayas, but also includes parts of the Indo-Gangetic Plain, bordering the Tibet Autonomous Region of China to the north, and India in the south, east, and west, while it is narrowly separated from Bangladesh by the Siliguri Corridor, and from Bhutan by the Indian state of Sikkim. Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the world's ten tallest mountains, including Mount Everest, the highest point on Earth. Nepal is a multi-ethnic, multi-lingual, multi-religious and multi-cultural state, with Nepali as the official language. Kathmandu is the nation's capital and the largest city. The name "Nepal" is first recorded in texts from the Vedic period of the India ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-bloc ...

Imja Glacier
Imja Glacier ( ne, इम्जा हिमनदी) is located in the Himalayas, in the Solukhumbu District of Nepal. It originates on the western face of Kali Himal, , and skirts the southern slopes of Imja Tse or Island Peak, south-east of Mount Everest. It is joined by the Lhotse Shar and Ambulapcha Glaciers. The glacier forms the eastern extent of Imja Tsho, which in turn drains through the Dingboche valley to the Imja Khola, Dudh Kosi, Ganges River and finally the Indian Ocean.

Ganges River
The Ganges ( ) (in India: Ganga ( ); in Bangladesh: Padma ( )). "The Ganges Basin, known in India as the Ganga and in Bangladesh as the Padma, is an international river to which India, Bangladesh, Nepal and China are the riparian states." is a trans-boundary river of Asia which flows through India and Bangladesh. The river rises in the western Himalayas in the Indian States and union territories of India, state of Uttarakhand. It flows south and east through the Gangetic Plain, Gangetic plain of North India, receiving the right-bank tributary, the Yamuna, which also rises in the western Indian Himalayas, and several left-bank tributaries from Nepal that account for the bulk of its flow. In West Bengal state, India, a feeder canal taking off from its right bank diverts 50% of its flow southwards, artificially connecting it to the Hooghly river. The Ganges continues into Bangladesh, its name changing to the Padma River, Padma. It is then joined by the Jamuna River (Bangladesh), ...

Terminal Moraine
A terminal moraine, also called end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from a previou ...

Imja Tse
Imja Tse, better known as Island Peak, is a mountain in Sagarmatha National Park of the Himalayas of eastern Nepal. The peak was named Island Peak in 1953 by members of the British Mount Everest expedition because it appears as an island in a sea of ice when viewed from Dingboche. The peak was later renamed in 1983 to Imja Tse but Island Peak remains the popular choice. The peak is actually an extension of the ridge coming down off the south end of Lhotse Shar. The southwest summit of Imja Tse was first climbed in 1953 as part of a training exercise by a British expedition that went on to summit Mount Everest. The team who climbed Imja Tse comprised Tenzing Norgay, Charles Evans, Alfred Gregory, Charles Wylie and seven other Sherpas. The main summit was first climbed in 1956 by Hans-Rudolf Von Gunten and two unknown Sherpas, members of a Swiss team that went on to make the second ascent of Everest and first ascent of Lhotse. Climbing route To climb Island Peak, one has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake Outburst Flood
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. Definition A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glac ...

Glacial Lakes Of Nepal
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period wi ...
