The 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.

👉 Nordenskjöld Lake in the context of Glacial flour
Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk.
When the sediments enter a river, they turn it grey, light brown, iridescent blue-green, or milky white. If the river flows into a glacial lake, the lake may appear turquoise in colour as a result. When appearing as any shade of blue, the colour is most commonly caused by the Tyndall Effect, with the particular hue determined by suspended particle size. When flows of the flour are extensive, a distinct layer of a different colour flows into the lake and begins to dissipate and settle as the flow extends from the increase in water flow from the glacier during snow melts and heavy rain periods. Examples of this phenomenon may be seen at Lake Pukaki and Lake Tekapo in New Zealand, Lake Louise, Moraine Lake, Emerald Lake, and Peyto Lake in Canada, Gjende lake in Norway, and several lakes (among others, Nordenskjöld and Pehoé) in Chile's Torres del Paine National Park, and many lakes in the Cascade Range of Washington State (including Diablo Lake, Gorge Lake, and Blanca Lake).

Nordenskjöld Lake in the context of Lake Pehoé
Lake Pehoé (Spanish pronunciation: [peoˈe]) is a surface water body located in Torres del Paine National Park, in the Magallanes Region of southern Chile. The lake is fed mainly by Paine River through the Nordenskjöld Lake, but it also receives the water from the outlet of Skottsberg Lake.
The water of Paine River feeding the Pehoé Lake have emerged from the Salto Grande waterfall. In this upper reach of the Pehoe Lake watershed there are numerous flora and fauna, including grazing wild guanaco.
