There are six small lakes and many hillocks in the Kijiyama Highland, 300-600m above the sea level in the southeastern part of Akita prefecture. These lakes and hillocks were formed by an ancient landslide in the area of the Miocene Sanzugawa lucustrine deposits. To the south of Lake Kainuma, boulders are flown down the northern and the eastern slopes of Mt. Kabuto (669.8mm) (arrows in illsutration), covering the landslide materials. Landslide materials and boulders cover the terraces of the Minase river. These relation presents an interesting problem on the paleoclimatology of the area.
