Because it was a mine, the drop in height is very quick. That building – that was used for prison and mining operations is actually four floors in height. Most if it is underwater!

Very interesting how wind and water has eroded what is left after limestone mining. Almost looks like sharp edges.

This is the original place I wanted to come to. The limestone quarry is stripped off the limestone and this is what remains. During the mining, big Soviet pumps were used to drain out the water. The story goes that when the Soviets retreated the valuable copper in the coils were stolen. The pumps stopped and the underground water soon filled up the hollows. Since this is water coming from the ground, it is very clear and cool.

The famous prison of Murru Vangla. There were three prisons inside that complex. They were built specifically here next to the quarry to keep the prisoners busy.

Over 700 years old!!

We were a few feet away from that hole. And thru that hole, if you carefully observe, you can see all the way to the bottom into the water. Apparently, last season, this hole was not here. And after this winter, as the snow softens the ground and ice starts expanding, that piece of land is going to fall down to the very bottom!!
