DISCUSSION TOPICS
1. How conclusive is the evidence for the former existence of perennially-frozen ground
in mid-latitude regions during the Pleistocene?
2. Why is the distinction between seasonal and perennial frost important in Pleistocene
periglacial reconstruction?
3. What were the physical and structural changes that occurred when Pleistocene perma-
frost degraded?
