“Light” lake is a symbol of Sayan. It’s often called “Big” as its calm hyaline lies 1.5-2km north and south and 1km east and west. It’s about 1200m high above the level of the sea. It’s margined with dense cedar-deal forest that mounts the nearest chute hills. Two Ergaki peaks: Bird and Starry rises above the lake and taiga for one kilometre. Between them lies the large cirque covered with white mist. Forest, mountains, peaks and cirque - everything is mirrored in calm waters of the lake.
Bear Lake is a quiet beatific nook. Its warm waters draw on to their clarity. Old-timers say that once this lake was a favourite place of taiga master: a bear, so in his honour it was given this name. Really, the numerous snags resemble set bear figures not only in daytime but also in nights.
Marble lake got his name for its pure glacier water. It’s 1598m high above the level of the sea. There is a waterfall 100-120m far from the lake. Cascading from 30-40m height, it forms two or three steps with steep streams between them. Underlying bed consists of mass craggy granite bars: big parallelepipeds which look like giant red steps due to a great many microorganisms on them. The waterfall is in the flower of its beauty in spring, in period of intensive thawing of snow.
Not far from the waterfall (in 100-120m), there is a source of the mountain river Jerboa (“Tushkanchic”). It springs from a cirque joining one of the main peaks (2200m high). In the middle of summer the water heats up to 16-18°C and one may swim in it.
In the ravine from the Younger brother side, there is emerald mountain lake. It has a shape of a rectangle (nearly a square) with rounded off corners and its origin is wrapped in mystery. It’s called “Lake of mountain spirits”. One of its best sights is a waterfall, which cascades from 20m height as an all-over roaring stream.
