Glacial Lakes of Elbrus
Most mountain lakes are formed by glaciers, forming natural dams. As the glacier advances, it piles up mounds of rock, clay, and sand—moraines—before it. As the ice retreats, the glacial dams disappear, and the water drains away. If the lake's shape follows the contours of the glacial path, it is called a moraine lake.
Glacial lakes can be uninhabited—due to the glacial conditions, they are devoid of fish and algae blooms. Furthermore, lakes along the route can disappear and reappear depending on glacier melt and the accumulation of water in natural basins, and can also change shape and location.
Many glacial lakes remain unexplored. Scientists are only beginning to study their chemical composition, depth, and ecosystem characteristics.
Lake Elbrus (Azau) is located at an altitude of 3,227 meters and is surrounded by moraines and cliffs. The glacial water in the lake reaches 5–7°C. It is a popular spot for trekking and photography.
