Аннотация

A number of tephrochronologically correlated and dated sedimentary sections provide
evidence for the existence of a giant lake filled the Central Kamchatka depression 30-11 thousand years ago. The lake extent bounded by CKD borders is estimated to be ~10 000 km² . This estimate makes this lake comparable in size to the famous Late Pleistocene glacial Lake Missoula.
