In many peat bogs, especially in Northern Iceland, the transition from subboreal to sub- atlantic conditions is very marked, indicating a sudden and great change in the climate, which seems to have become both colder and more humid. For a period of unknown length the subatlantic climate must have been a little more favourable for glacier growth, viz. a little more severe, than the climate of the “Little Ice Age”. This period was long enough to bring highly alpine glaciers in Iceland frorn their minimum to their maximum extension in Post- glacial Time, but not long enough to bring outlet glaciers with a flat intake area to a similar position.
