Lake Failure
gagarin Boulevard, city of Pyatigorsk
Description:
The real pride of the resort part of Pyatigorsk is represented by the karst cave "Proval" in the form of a huge cone-shaped funnel located on the slope of the mountain peak Mashuk.
An unusual stone bag inside the mountain, which has a diameter of 15 meters and a height of 41 meters, is characterized by the presence at the bottom of a blue hydrogen sulfide lake with a depth of eleven meters. Its unusual turquoise coloring warm waters of the lake owe special bacteria.
In the nineteenth century, a long tunnel was dug in the direction of the lake, which made it possible to actively use water for medicinal purposes, for the device of "Sham baths". Today, a small font made of natural stone can accommodate a couple of people. The water here even in severe winter frosts is warm.
