| Research Abstract |
The occurrence of permafrost was confirmed at four observed points in the summit area of Mt. Daisetsu. The extrapolation of the lower part of the ground temperature profile from 10m bore-hole, which installed during this study, indicates the depth of the permafrost base to be 30-40m. I monitored two ground temperature profiles down to 3m on the summit of Mt. Fuji, but I have not confirmed the occurrence of permafrost. Analysis of boring cores from Siberia and Japanese mountain permafrost showed similar characteristics of cryostratigraphy.
