I went sightseeing in Chibanian

#0yentripnovember I booked a local guide and listened to his explanation as I visited the geomagnetic reversal layer (Chibanian) in Tabuchi, Yoro River Basin. Apparently, the geomagnetic reversal can be seen at the boundary of the volcanic ash layer of Mount Ko-Ontake, which erupted about 770,000 years ago. Of course, you can't see the geomagnetic reversal with the naked eye lol.
