Selfie on ancient Tetris

Today I made a short hike to Tupamäki where I heard to be a natural cave. I couldn't find any clear coordinates of the location from the web, thus I chosen personal exploration method and climbed on rocks all over the hill until I found a right place, which was of course the last expected place I was looking for. I found the cave, but didn't go down to the cave due that I was alone and never know what might happen as it would have required some risky climbing. Next time I shall ask someone with me as safeguard.

Nevertheless, I was even more impressed of those natural huge stone bricks which were around 5 -10 meters high. Some of you might know the old videogame called Tetris, where falling bricks are moved to right positions.Those ancient stone bricks remind me of that game as it looked like they have drop down from the heaven. All bricks are not visible in this image, as most of those are behind the last rock up (check the extra image). Hard to imagine power that can cut solid rock like that. It have to be enormous...
