Glacial lakeA 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. FormationNear 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.
Tyndall effectThe Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol). Also known as Tyndall scattering, it is similar to Rayleigh scattering, in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength, so blue light is scattered much more strongly than red light.
MeltwaterMeltwater (or melt water) is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found during early spring when snow packs and frozen rivers melt with rising temperatures, and in the ablation zone of glaciers where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form.
GlacierPersistent body of ice that moves downhill under its own weightGlacier of the Geikie Plateau in GreenlandThe Taschachferner in the Ötztal Alps in Austria. The mountain to the left is the Wildspitze (3,768 m), the second highest in AustriaThe Baltoro Glacier in Pakistan. It is 62 kilometres (39 mi) long, the fifth longest alpine glacier in the world.A glacier (US: ; UK: or ) is a persistent body of natural ice, a form of rock, that is constantly moving under its own weight.
SiltSilt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt can also be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud.
Peyto LakePeyto Lake ( ) is a glacier-fed lake in Banff National Park in the Canadian Rockies. The lake is near the Icefields Parkway in Alberta, Canada. It was named for Bill Peyto, an early trail guide and trapper in the Banff area. The lake is formed in a valley of the Waputik Range, between Caldron Peak, Peyto Peak and Mount Jimmy Simpson, at an elevation of 1,860 m (6,100 ft).
Moraine LakeMoraine Lake is a snow and glacially fed alpine lake in Banff National Park, 14 kilometres (8.7 mi) outside the village of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of approximately 1,884 metres (6,181 ft). The lake has a surface area of 50 hectares (120 acres). The lake, being fed almost completely by snow-melt and glacial-melt, does not reach its crest until middle to late June.
GjendeGjende (Vang dialect form: Gjendin) is a lake in Vågå Municipality in Innlandet county, Norway. It is located in the Jotunheimen mountain range and also inside Jotunheimen National Park. The proglacial lake shows typical characteristics of glacial formation, being long and narrow, with steep walls. The lake is 18 kilometres (11 mi) in length and only 1.5 kilometres (0.93 mi) in width at the broadest point.
Lake PukakiLake Pukaki (Māori: Pūkaki) is the largest of three roughly parallel alpine lakes running north–south along the northern edge of the Mackenzie Basin on New Zealand's South Island. The others are Lakes Tekapo and Ōhau. All three lakes were formed when the terminal moraines of receding glaciers blocked their respective valleys, forming moraine-dammed lakes. The Alps2Ocean mountain bike trail follows the edge of Lake Pukaki for part of its length.
Lake Louise (Alberta)Lake Louise (named Ho-run-num-nay (Lake of the Little Fishes) by the Stoney Nakoda First Nations people) is a glacial lake within Banff National Park in Alberta, Canada. Situated 11 km (6.8 mi) east of the border with British Columbia, Lake Louise is located 5 km (3.1 mi) west of the community of Lake Louise and the Trans-Canada Highway (Highway 1).
Lake TekapoLake Tekapo (Māori: Takapō) is the second-largest of three roughly parallel lakes running north–south along the northern edge of the Mackenzie Basin in the South Island of New Zealand (the others are Lake Pukaki and Lake Ōhau). It covers an area of 83 km (32 sq mi) and is at an altitude of 710 m (2,330 ft) above sea level. In Māori culture"Tekapo" is a misspelling of Takapō, the name of the lake in the Māori language. Takapō means "to leave in haste at night".
Emerald Lake (British Columbia)Emerald Lake is a freshwater lake in Yoho National Park, British Columbia, Canada. Yoho National Park is one of the four contiguous national parks in Canada's Rocky Mountains, along the boundary of British Columbia and Alberta Provinces.
Nordenskjöld LakeThe Nordenskjöld (Spanish: Lago Nordenskjöld or Lago Nordenskiöld) is a lake in Torres del Paine National Park in the Magallanes Region, southern Chile. The lake is named after the Swede Otto Nordenskjöld, who explored the region at the beginning of the 20th century. The outfall of Nordenskjöld Lake consists of a waterfall known as Salto Grande. At this western end of the lake on the southern side is an abundance of wildlife, including grazing guanaco.*As an Amazon Associate I earn from qualifying purchases.
