that signifi cant terrain damage occurred in the Yamal oil and gas fi elds throughout the
1980s and early 1990s.
Today, all aspects of resource exploration and development in permafrost regions are
closely regulated in order, among other things, to minimize thermokarst and environ-
mental damage. Further discussion of the geotechnical aspects of human settlement and
economic activity in periglacial environments is given in Chapter 14.

DISCUSSION TOPICS
1. What are the most common causes of thermokarst?
2. What happens when ice-rich permafrost degrades?
3. Discuss the origin of oriented thaw lakes.
4. Explain why thermokarst processes are some of the most important processes fashion-
ing certain periglacial landscapes.
