Surrounded by metamorphic, sedimentary and igneous rocks, the shores of Lake Baikal are pulled away from each other at a rate of two centimeters per year. Lake Baikal has many typical characteristics of the ocean - unfathomable depth, huge reservoir capacity, undercurrents, tides, strong storms, big waves, ever-increasing rift valleys, geomagnetic anomalies, etc. The Baikal Depression is asymmetrical, with the western slopes being steeper than the eastern ones.
