In vicinity of Kalgalaksha in the lacustrine-bog deposits core we found a layer of gravel with a clay-silt-sand filler. The granulometric composition indicates high hydrodynamic conditions of the its formation. Diatom analysis of the material, during which the shells of marine and brackish-water diatoms were discovered, complements the representation of the layer as a result of a tsunami.
