群馬県南西部、長野県境に接する火山。標高1423メートル。第三紀層の上に、安山岩や凝灰岩があり、山頂は南北約1400メートル、東西約400メートルの平坦(へいたん)な玄武岩の溶岩台地で、台地の北端は約170メートルの絶壁になっている。この台地上に荒船山神社がある。形がひときわ目だち、荒海を行く船の形にみえるのでこの名がついたという。長野県では砥石(といし)に例えて砥山(とやま)という。妙義(みょうぎ)荒船佐久高原国定公園に属し、高崎から上信電鉄下仁田(しもにた)駅下車、バスと徒歩による好適のハイキングコース。北方に神津(こうづ)牧場がある。 [村木定雄] 『佐川栄次郎著『荒船火山地質調査報文』(1898・震災予防調査会)』 [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
