Merzbacher Lake
Lake Merzbacher is a moraine glacier lake located in east Kyrgyzstan between the north and south Engilchek Glaciers in the Tien Shan Mountains. It is often called the "Disappearing Lake" because it drains every year as the ice melts, often causing a 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 j .... The lake was named after a German explorer, Gottfried Merzbacher, who led an expedition in the area in 1903. An ice dam prevents the lake from draining through the majority of the year however when a hole finally melts through the dam the lake drains within three days. When this happens, the lake's discharge can be up to 1000 m3 a second which causes destruction of infrastructure and creates major flooding downstream. It goes through this cycle of appearing, ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Kyrgyzstan
Kyrgyzstan,, pronounced or the Kyrgyz Republic, is a landlocked country in Central Asia. Kyrgyzstan is bordered by Kazakhstan to the north, Uzbekistan to the west, Tajikistan to the south, and the People's Republic of China to the east. Its capital and largest city is Bishkek. Ethnic Kyrgyz make up the majority of the country's seven million people, followed by significant minorities of Uzbeks and Russians. The Kyrgyz language is closely related to other Turkic languages. Kyrgyzstan's history spans a variety of cultures and empires. Although geographically isolated by its highly mountainous terrain, Kyrgyzstan has been at the crossroads of several great civilizations as part of the Silk Road along with other commercial routes. Inhabited by a succession of tribes and clans, Kyrgyzstan has periodically fallen under larger domination. Turkic nomads, who trace their ancestry to many Turkic states. It was first established as the Yenisei Kyrgyz Khaganate later in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Proven ...

Engilchek Glacier
Engilchek Glacier ( ky, Эңилчек, russian: Энильчек - ''Enilchek'', also Иныльчек - ''Inylchek'') is a glacier in the Central Tian Shan Mountains of Issyk-Kul Region, northeastern Kyrgyzstan. Its snout is 50 km east of the village of Engilchek. The South Engilchek Glacier ranks as the sixth longest non-polar glacier in the world and is the largest and fastest moving glacier in Kyrgyzstan. The main glacier has two arms, the North and South Engilchek Glaciers. The latter is longer and provides an overall length of . with an area of and an ice thickness of roughly 150–200 m in the bottom parts. The glacier stems from the Chinese-Kazakh-Kyrgyz massif of Khan Tengri and Pik Pobedy and the upper part of the glacier falls in all three countries. Meltwater from the glacier feeds the Engilchek River, a tributary of the Saryjaz (known as Aksu in China), which crosses the Chinese border into the Tarim Basin. Water from this glacier also feeds the seasonal g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tien Shan Mountains
The Tian Shan,, , otk, 𐰴𐰣 𐱅𐰭𐰼𐰃, , tr, Tanrı Dağı, mn, Тэнгэр уул, , ug, تەڭرىتاغ, , , kk, Тәңіртауы / Алатау, , , ky, Теңир-Тоо / Ала-Тоо, , , uz, Tyan-Shan / Tangritog‘, , also known as the Tengri Tagh or Tengir-Too, meaning the ''Mountains of Heaven'' or the ''Heavenly Mountain'', is a large system of mountain ranges located in Central Asia. The highest peak in the Tian Shan is Jengish Chokusu, at high. Its lowest point is the Turpan Depression, which is below sea level. One of the earliest historical references to these mountains may be related to the Xiongnu word ''Qilian'' ( zh, s=祁连, t=祁連, first=t, p=Qílián) – according to Tang commentator Yan Shigu, ''Qilian'' is the Xiongnu word for sky or heaven. Sima Qian in the ''Records of the Grand Historian'' mentioned ''Qilian'' in relation to the homeland of the Yuezhi and the term is believed to refer to the Tian Shan rather than the Qili ...

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 ...

Mountain Lakes
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...
