In-Depth Information
BIL had 13,300 cal. years BP, the same water level as in Lakes Peipsi and
Võrtsjärv, because these water bodies were connected via strait systems in central
Estonia.
According to shoreline and bathymetry reconstructions, the land uplift induced
gradual isolation of Lakes Peipsi and Võrtsjärv from the BIL, which occurred before
the Billingen drainage.
Glacial Lake Võrtsjärv isolated from BIL at about 12,400-12,000 cal. years BP,
most likely before the BI stage.
Glacial Lake Peipsi isolated from BIL in between 12,400 and 11,700 cal. years
BP, thus before BIII stage.
Shore displacement of the BIL in eastern Baltic was regressive due to the land
uplift.
