In three wells drilled in the south of the city of Trento into the sediments filling the valley of the Adige river at 11, 31 to 33, 130 and 139 m depth fragments of wood have been found and dated by radiocarbon method. From this dating results that the sedimentation rate in the valley of the Adige river was around 10,000 years B.C. extremely high, up to 130 mm/y and decreased after that lime rapidly to a rate of around 2 to 3 mm/y remaining rather constant until now. The high sedimentation rates around 10,000 years B.C. correspond to the climatic optimum that produced a rapid deglaciation in the Alps and an uplift of the Mediterranean Sea.
