Description :
Fewer freeze-thaw cycles were recorded in the air than at 1 and 3.5 cm in the bedrock, between December 1983 and April 1984. The number of cycles that could be declared geomorphologically effective according to established temperature criteria was normally less than half the total number of freeze - thaw cycles recorded in both air and bedrock. Under the current temperature regime at the field site, few effective cycles are capable of penetrating more than 5 cm into the free face.
