In the summer of 1914, geological investigations were carried out in the area of the Aleksandrovskaya Dacha (Perm Governorate), led by Professor N. N. Yakovlev of the Mining Institute. I worked in the eastern part of the dacha, and there I was able to observe the interesting geological phenomena that provided the material for this note. The most remarkable of all these phenomena in this locality should be considered the sinkholes (see the article). Among other interesting phenomena, caves can be noted. Of these, the most interesting in terms of size, shape, and origin are two. The first, the Vsevolodovskaya Cave, is located at the very endof the limestone cliffs, extending beneath them on the bank of the Chanva River. Initially, it has the appearance of a large niche, in the side of which there is a cleft that goes into the depths and stretches (together with the first niche) for 20 sazhens. Inside this cave there is a lake, gradually deepening towards the end of the cave. In the depths of the cave, approximately halfway, the cave walls 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.
