Gandate, Natural monument in Gero, Japan.
Gandate is a rock formation in Gero featuring distinctive columnar structures created by the cooling of lava flows. The towering stone columns create a striking pattern that stands out dramatically against the surrounding landscape.
This formation came into being when lava from a volcanic source cooled and solidified at this location long ago. The cooling process created the distinctive vertical column patterns that remain visible today.
The Gandate monument represents a designated natural heritage site in Gifu Prefecture, contributing to local geological education and research initiatives.
The site can be reached from Gero Station and conditions vary throughout the year depending on weather. It is helpful to ask locally about the best access routes and current ground conditions before your visit.
The formation consists of pyroxene andesite from the Marishiten-yama sixth lava flow, creating an extraordinary geological structure in the region.
