At the end of 2013 Mutabor had finished the reparation of his car "Moskvitch" and decided to use this opportunity to visit the underground river Poneryotka in Novgorod region. Being the only large natural cave relatively not far from Petersburg, Poneryotka is a very interesting place.
Mutabor and Lanivs had arrived to the place, the very nice valley of the Msta river. Mutabor tried to enter the cave, but had failed because the passage was too low, and flloded with a very cold water, so water mocassines were not sufficient to crawl there. A full-body waterproof suit was necessary to explore the cave (pic 1–9). So the friends had deciced to visit the place they had mentioned on the way: a strongly ruined country estate (pic 10–21).
