To be honest, when I stumbled upon the caves in the Leningrad region, I was amazed to the core! Anything … but caves, and almost openly they are called man-made, some are called catacombs, some caves, and some, as it were, are considered natural! I thought that the Leningrad region and Karelia are a country of swamps and lakes, but it turns out this is a country of caves too!
But it turned out that this is still a country of waterfalls … I'm not talking about Karelia. Caves first …

Than they were chopped, obviously not with a chisel and not with a pick or a mammoth bone! Who chopped? Wild Finnish tribes without iron before the arrival of the Oldenburgs? And most importantly, why? Of course, there are obvious mountain penetrations, for example, the Sablinskie caves - this is the extraction of limestone and quartz sand, there are also kilns for firing, like a cement plant …
But there are many different caves in old Ladoga, for example, "Tanechkin" caves …
But I was especially impressed by the Tosno waterfalls near the Sablinskie caves. Waterfalls are certainly from the category of amazing natural objects! When I wrote about the Vokhov and Nevsky rapids, I expressed the assumption that the rapids were formed on the site of hydraulic structures but destroyed as a result of a natural disaster (flood) or "war of the gods": "The Volkhov rapids. The way from the Varangians to the Greeks and back …".
If the Tosna River were as abundant as the Vokhov or the Neva, then these waterfalls would also be called rapids …
Of course, purely natural phenomena … but if you look closely, some of the photos have obvious remains of buildings.
To be honest, I just don't have enough decent words - where are the unique natural objects here? An industrial zone, of course, there should be dams on the river, maybe water mills … but not to admit this to human activity … you have to be an archaeologist
