Mean ages of 94 ka and 121 ka were obtained at Oulainen for two sand layers situated above and below an organic deposit previously correlated with the Brörup interstadial. At Vimpeli, TL dates obtained for sand layers embedded in an organic deposit suggest an age for this deposit of 107 ka. The uncertainty in this result is considerable, however. Problems encountered in dating these sediments and the reliability of the results are discussed.
