Hachimantai is a plateau-like volcanic terrace, 1,400-1,600 meters above sea level, extending over Iwate Prefecture and Akita Prefecture. The plateau is composed of aspite volcanoes in various shapes. Numerous ponds and swamps are dotted among the peaks. The highest peak is at 1,613 m above sea level. In winter hard rime is formed on Maries' firs, which are called “Snow Monsters.” Skiers can enjoy endlessly continuing snow monsters on a fine day.
