Kushiro moor is a wide, flat and swampy plain surrounded by the two marine terlaces on the east, north and west, and a long and narrow belt of sand dunes on the South coast. Its paleogeographic changes seem to have occurred in the Alluvial age, as is shown the following table. The change could be deduced from the correlation between the Alluvial shell-fossils and the prehistoric shell- mounds and remains, and from the topographic features.The gentle tilting which had occurred during the regression formed the present topographic features that the plain has a general slope to southeast, the lakes lie only on the eastern margin. the coast is advancing foward to the west, etc.. The formation of swampy plain was due to its low-level and the sand dunes.
