椿の白岩 - Oga

A little landmark. Nostalgic.

It is a rare strange rock.

There is a gym in such a place !! Moth

This year, it was hot but it was great to relax.

Oga Peninsula, Akita Prefecture, which is also certified as a Geopark. Recently, an NHK program "Going to the Geo Japan Superb View Archipelago" has been broadcast in a series. In Akita Prefecture, there are many scenic spots such as Oga Peninsula Ogata Oyasukyo Happo Shirakami Kisakata Mt. Chokai and other geoparks. At the beginning of the NHK program, "Did you know that there is a miraculous land on this earth? It is our Japanese archipelago. A variety of terrain Rich water and greenery and a lot of superb views The Japanese archipelago like this treasure How was he born? Going to the Geo Japan Japanese Archipelago, which reveals the secrets of the unknown earth and tells the story of the birth of the archipelago. " Visit Yamazaki, a coastal building in Oga City, Akita Prefecture, which was featured in this program. On the cliff facing the Sea of ​​Japan, the rock surface that seems to have been shaved only and the light green color are eye-catching. Hotokegaura on the Shimokita Peninsula, Aomori Prefecture Many similar strange rocks and megaliths can be seen at Cape Shakotan, Hokkaido. In these three areas, there is a fragile rock called green tough, which is the same stone and is made by solidifying green volcanic ash. The ones that are green are those that have been altered by heat and can be seen on the Sea of ​​Japan side of eastern Japan in addition to these three locations. This is proof that all the formations with this stone were made in the same period. Thirty million years ago, the Japanese archipelago was still attached to the edge of the continent. The tensile period up to 10 million years ago was the time when eastern Japan in Tohoku and Hokkaido was pulled, and these stones were made by depositing volcanic ash. And it appeared on land by the subsequent uplift. Eastern and western Japan moved away from the continent 15 million years ago in the Tertiary of the Cenozoic. Then, the Sea of ​​Japan was born, and a submarine volcano erupted, and the volcanic ash accumulated over 1000 m in thickness and solidified, which became the source of green toughness. Then, the 4th Cenozoic Japanese archipelago after 3 million years ago entered the compression period, and the rocks on the seafloor pushed out by the plate subduction began to rise. The energy compressed from both the east and west and the high-temperature water contained in it break the bonds between the covalent crystal molecules of the rock and melt them to form magma and eject it to the ground. There was also a volcanic belt lined up in two rows at 50km intervals in the Tohoku region. Due to the uplift and volcanic activity caused by east-west compression since 3 million years, the land has expanded to its present form. Around this time, green toughness also appeared on land.

It is on the opposite side of the camellia fishing port across the road. Some parts are difficult to see due to trees and grass. I think it's a good idea to park your car in the fishing port and go see it.
