In the Ångermanälven river valley in northern Sweden the Swedish geochronological time scale has been connected with the present (1978) by means of varved clayey‐silty sediments. A 75‐year‐old problem has thereby been solved. Ragnar Lidén's previously calculated gap of 980 years between his youngest varve 7,522, found at Prästmon, and the historical year 1900 A.D. should be extended by 365 years. This implies that the zero year in Döviken (Indalsälven river valley), reviewed by Borell and Offerberg and commonly used in the Swedish time scale to mark the boundary between the finiglacial and postglacial epochs is Sweden, should be dated to 7,288 B.C. (9,238 B.P.) instead of the old date 6,923 B.C. given by Nilsson in 1960.
