History of its marshland

Mashland in Tsugaike National Park was formed during the volcanic activity of Mt. Norikura.
First, volcanic activity formed stair-like fault on Otari-village side of the mountain, then created the flat side.
This is where Tsugaike National Park・Tenguppara・Kaminotanbo are now located.
Then, depression contour of the flat side formed the ponds, where peat moss and cotton grass started growing.
Those plants withered away but never decayed, then became peaty under the cold weather. And finally new vegetation started growing on top.
This is how the marshland in the park was formed over a long period of time.
