On the upper slopes of Mt. Takayama (532 m), north of Susa Bay, boulders of quartz gabbro are exposed, with a strong magnetism like that of natural magnets. The nearer a boulder is to the summit, the stronger its magnetism, and it weakens with distance. It is rare for a rock that is not magnetite to be this magnetic, and it was designated a National Natural Monument in 1936.
