群馬 三波石峡 Gunma Sanba-sekikyou Sanbaseki Gorge
|
Sanbaseki Gorge in the border of Fujioka City, Gunma Prefecture and Kamikawa-machi, Kodama-gun, Saitama Prefecture is nationally designated as a Place of Scenic Beauty and a Natural Monument. Surrounded by steep cliffs, the 1.5 km riverbed of the Kannagawa River is dotted with 48 huge or monstrous-shaped rocks. As early as in the Edo period (1603-1868), names were given to each of these oddly-shaped stones, which were collectively called “the 48 Fine Stones” and the gorge was a popular scenic spot visited by a lot of sightseers.
The gorge is considered to be a geologically precious zone, where green crystalline schist crops out on the ground. In the Meiji period (1868-1912), Kofuji Bunjiro, the founder of Japanese geology, discovered crystalline schist in the area around the Sanba River and named it Sanbagawa crystalline schist, from which the name “the Sanbagawa metamorphic complex” derived later.
With yellow and white stripes on the green stone surface, Sanbagawa crystalline schist, or popularly called Sanba Stone, creates mysterious and wonderful scenery in each season.
