Near Rovagnate (Como) Late Glacial and Holocene biogenic sediments at the top of a glaciolacustrine sequence have been dated: the obtained ages extend from 10620 ± 60 B.P. to 4780 ± 80 B.P. At Pontida (Bergamo) Würmian glaciolacustrine sediments have been dated 17700±360 B.P. This age can also be referred to the ice margin location of the Adda piedmont glacier, which directly dammed the lake of Pontida. Finally wood remains contained in the lacustrine sediments of Pianico (Bergamo) gave l4C ages older than 43 000 years B.P., which do not disagree with the traditional assignment of these sediments to the Riss/Würm.
