Ruskeala failureRuskeala failure — is in Karelia, a huge hole in the ground somewhere in the depth of ten meters — water, darkness … Judging from the local people, the failure was formed in the sixties of the last century, after a strong explosion in a nearby quarry. The roof of the old waterlogged tunnels broke and fell into the water. On the surface revealed an impressive oval hole about 20 by 30 meters.

It is roughly in the center of production, the perimeter of which today can be estimated at about half a kilometer. This underground rounded area was associated with dry galleries with the main part of this mountain park, but they are now closed rubble.

The main feature of failure — a special microclimate. Due to the effect of cold ice bag in distant parts of the production does not melt ever. On it you can walk with caution, even in summer. Another thing — the very place of failure. It accumulates through the winter cold, but in the summer, warm air melt and rain water slowly melt the lake in the form of repeating the inlet.

Starting in June, researchers need to first go down the rope into the dinghy, and then landed with her to melt the ice. For experienced cavers plumb the depth of 12 meters is not a serious obstacle, but in combination with water and ice, this descent can pretty tickle nerves. Experience is not simple, but interesting.
