Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ...

Réserve Naturelle Nationale De Passy
The Passy National Nature Reserve is a nature reserve located on the face of the Aiguilles Rouges and Mont Blanc mountain ranges, in the middle of the Arve valley, in the Haute-Savoie metropolitan department of France. The have been protected since 1980; the reserve assures a continuous link of protected areas between the Sixt-Passy National Nature Reserve and the Aiguilles Rouges National Nature Reserve. The natural history of the reserve mirrors that of the surrounding mountains. The young rock cliffs of the Fiz mountain range dominate the former Pormenaz mountain range. The tectonic activity of the Alps continues to bring the Fiz rock cliffs closer to the silicious rocks of the Pormenaz. This mineralogical history caused a great diversity of land areas such as meadows, heaths, and wetlands, which are inhabited by numerous species such as eagles and Alpine Ibexes. This landscape testifies to the geologic history of the area: the of vertical walls of the calcareous clif ...

Lac De Pormenaz - Réserve Naturelle Nationale De Passy
Lac is the resinous secretion of a number of species of lac insects, of which the most commonly cultivated is ''Kerria lacca''. Cultivation begins when a farmer gets a stick that contains eggs ready to hatch and ties it to the tree to be infested. Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac. The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other material. The resulting product is known as seedlac. The prefix ''seed'' refers to its pellet shape. Seedlac, which still contains 3–5% impurity, is processed into shellac by heat treatment or solvent extraction. The leading producer of lac is Jharkhand, followed by the Chhattisgarh, West Bengal, and Maharashtra states of India. Lac production is also found in Bangladesh, Myanmar, Thailand, Laos, Vietnam, parts of China ...
