Ground ice as an initiator of landforms in permafrost regions

The role of ground ice as an initiator of landforms in permafrost regions implies also the formation of landforms which result from the melting of ground ice. Many landforms in permafrost regions owe their origin to the build-up of ice in the ground. Several types of prominent features are formed by...
