What You're Watching

This camera provides a live view of Jonen Mountains. Geological Origins The Jonen Mountains, rising majestically above the valley floors of northern Nagano Prefecture, present a complex geological tapestry that has taken shape over millions of years. These peaks owe their existence to the interplay of the Eurasian and Philippine Sea tectonic plates, with convergent forces slowly uplifting sedimentary and volcanic layers to form the craggy relief s.

History & Context

Geological Origins The Jonen Mountains, rising majestically above the valley floors of northern Nagano Prefecture, present a complex geological tapestry that has taken shape over millions of years. These peaks owe their existence to the interplay of the Eurasian and Philippine Sea tectonic plates, with convergent forces slowly uplifting sedimentary and volcanic layers to form the craggy relief seen today. Deep beneath the surface, subduction processes initiated during the late Miocene provided the primary impulse for crustal thickening, while subsequent erosion and glaciation sculpted the ridgelines into their current dramatic contours.
