During the early part of the stadial snow-beds were probably extensive, since taxa considered to be chionophilous made significant contributions to the pollen spectra. Mineral sedimentation involved at first fine and then coarser particles. It is inferred that at first some summers were warm enough to permit thermal stratification of the kettle lake, but later cooler and perhaps windier summers prevailed. The most extreme conditions of the stadial, represented by the Artemisia maximum, were marked by a probable reduction in snow-beds, a decrease in the rate of sedimentation and in the size of mineral particles, and a fine lamination of sediment which suggests cold monomictic conditions in the lake. Oceanic conditions returned to the kettle site towards the close of the stadial| snow-beds appear to have become more extensive, more sediment entered the lake and more active summer circulation prevented the preservation of laminations.
