In the south of Western Siberia, there are lakes of a specific shape - teardrop-shaped, with a convex rounded side facing northeast and a pointed end-to the southwest. They are found only in the distribution area of the definite grivas relief. There is a complete gradual transition from symmetrical "drops" through to varying degrees asymmetric to special forms-lakes - "retorts". The necks of the "retorts" are twisted counterclockwise. Asymmetrical lakes are tentatively interpreted as the result of vortex currents in the Grosswald continuous flow.
