Mount Kashima-Yarigatake

Located on the border between Nagano and Toyama prefectures, this mountain is part of the Ushiro Tateyama mountain range, which forms the northern part of the Northern Alps. It is a double-peaked mountain located in the northwest of Omachi city in Nagano prefecture. Its altitude is 2,889 meters. The peak juts out like a spear, and so it was named after the place name Kashima at the foot of the mountain. The peak splits into two peaks, the southern and northern spears, and the beauty of the hanging ridge that connects the two peaks is magnificent, and the unique mountain shape can be seen even from afar. The eastern side is a steep slope that drops into the head of the Kashima River valley. In this valley lies the village of Kashima, said to be the descendants of defeated Taira warriors, and it enshrines a sub-shrine of Ibaraki Prefecture's Kashima Shrine. To the west, it slopes gently into the valley of the Kurobe River. It is said that the topography in the northeastern part of the peak, near the source of the Kashima River, was caused by glacial erosion. Between the summit and Mt. Jigatake to the south and Mt. Goryu to the north is the Hachimine Kiretto (a sharply cut saddle), which is a difficult spot on the traverse. The traverse takes about six hours.

長野・富山県境にあって北アルプスの北部をなす後立山連峰(うしろたてやまれんぽう)の山。長野県大町市街の北西部にある双耳峰。標高2889メートル。山頂は槍状に突出するところから、山麓(さんろく)の地名鹿島をとりこの名がつけられた。山頂の尖峰(せんぽう)は南槍と北槍の二つに分かれ、両槍を結ぶ吊(つり)尾根の美しさはみごとで、遠方からでもその独特の山容が認められる。東側は急斜面で鹿島川の谷頭に落ち込む。この谷に平家の落武者の子孫と伝える鹿島の集落があり、茨城県鹿島神宮の末社を祀(まつ)っている。西方黒部川の谷へは緩やかな傾斜で臨む。山頂の北東部、鹿島川の源流付近の地形は氷食によるともいわれている。山頂の南に爺ヶ岳(じいがたけ)、北の五龍岳(ごりゅうだけ)との間には八峰キレット（鋭く切れ込んだ鞍(あん)部）があり、縦走路の難所となっている。縦走には約6時間かかる。
