Funnels and caves of the Aleksandrovskaya Dacha in the Urals and phenomena associated with them

Abstract

In the summer of 1914, in the area of ​​the Aleksandrovskaya dacha (Perm province), a geological research led by the professor of the Mining Institute N.N. Yakovlev was carried out. I had to work in the eastern part of the dacha, and there I was able to observe those interesting geological phenomena that provided material for this note. The funnels are most remarkable of all these phenomena in this area (see article). Caves are among the other interesting phenomena. Of these, two are the most interesting in size, shape and nature of origin. The first, Vsevolodovskaya, is located at the very end of the limestone cliffs, going under them on the bank of the Chanva River. At first it looks like a large niche, in the side of which there is a gap that goes deep and stretches (together with the first niche) for 20 fathoms. Inside this cave there is a lake that gradually gets deeper towards the end of the cave. In the depths of the cave, approximately halfway, the walls of the cave are covered with stalactite deposits. The floor of the cave is littered with irregular blocks and fragments of limestone, which are also found under the water at the beginning of the lake.
