Description
The field data on the air and ground temperature at Onneyu-Tsutsujiyama obtained during the period from June, 1972 to September, 1973 show clear distinction between the normal ground and the cold anomaly. The nineteen cold anomalies in Kitami region, including at Tsutsujiyama, studied in 1972 and 1973 are characterized by their severe frost-shattering and-cracking producing block-slopes and protalus ramparts, and the abnormal ecological environment of high mountain level contrasted to the normal surrounding areas.<BR>The source of low temperature for the cold air circulating through the spaces within block-slope is believed to be the preserved sporadic permafrost or its more or less decayed relict produced during the last glacial period. The present average annual air temperature and day-degree value are too high to produce it now.<BR>Thus, the more the amount of cold air blowing out from the spaces of block-slopes and frost-cracked bedrock and warm rain-water permeating into them is, the decaying rate of cold source is believed higher.
