Abstract
Geomorphology of terraces and related features around Sapporo and several other districts in Hokkaido have been compared. The cause of geomorphic change in the last Glacial Age and its relation to climatic change are briefly discussed and reviewed.
In that Age nearly same fluvial geomorphic changes occurred in these places. The large accumulation in the valley and piedmont region is found to have occurred once. Alluvial fan and aggradational terrace of the substage were already in dissectional phase at the time some what earlier than 30, 000 14C years B.P. The cause of the accumulation may be of climatic origin, but the correlation between climatic records and geomorphological events in these regions is not clear.
