天人峡七福岩 Tenninkyo Gorge

北海道上川郡東川町に位置する天人峡は、大雪山国立公園の南西山麓、忠別川の上流に広がる延長約8kmの峡谷です。その渓谷美を象徴する「七福岩（しちふくいわ）」は、地球の巨大な火山活動と忠別川の長年の侵食作用によって形成された、学術的にも価値の高い柱状節理の岩峰群です。 紅葉シーズンには、灰褐色の岩肌や常緑樹の中に、カエデやナナカマドなどの赤や黄色が映え、火山地形と豊かな植生が織りなす優れた色彩対比を見ることができます。 Located in Higashikawa-cho, Kamikawa-gun, Hokkaido, Tenninkyo is an approximately 8-kilometer-long gorge spreading across the southwestern foothills of Daisetsuzan National Park along the upper reaches of the Chubetsu River. The "Shichifuki-iwa" (Seven Gods Rock), which symbolizes the gorge's scenic beauty, is a group of column-jointed rock peaks of high academic value, formed by massive volcanic activity of the earth and long years of erosion by the Chubetsu River. During the autumn foliage season, the red and yellow colors of maples and mountain ashes stand out against the grayish-brown rock surfaces and evergreen trees, presenting a magnificent color contrast woven by the volcanic topography and rich vegetation.
