The origin of this lake still remains a mystery! The lake is considered to be dying, but it dies in an unconventional way, it does not become swampy as usual from the bottom from the shore to the center, but is covered with a powerful grass-moss cover (raft) that does not stick to the bottom.
On the powerful raft grows undergrowth of small pines and birches, which float on the water like a kind of trampoline, it is dense and strong enough to withstand the weight of a person closer to the shore. A unique feature of the lake are the floating islands, these are fragments of raft that have broken away from the shore along well-trodden paths. The islands float under the influence of the wind on large trees (like on sails).
