Volcanic Ash Layer near the Mikagawa River(Mikagawa-no Kazanbai-so)

三ケ川の火山灰層

Evidence of massive volcanic eruptions in ancient times

You can see a volcanic ash layer along a section of the Ohechi route of the Kumano Kodo; the ash accumulated here are some of those ashes that were released during a series of massive eruptions that occurred 27,000 to 29,000 years ago in a volcanic system in Kagoshima Prefecture called the “Aira Caldera.” A signpost that indicates the location of this ash layer stands near the entrance gate to the forest trail, which is located close to the Mikagawa River.
