Iwami Tatamigaura Beach石見畳ヶ浦
It is the scenic spot designated as a national natural monument, which was the only one selected from the prefecture as one of the "100 Kaori Landscapes" selected by the Ministry of the Environment. "Kaori" means "scent" and the whole area has certainly a scent of rocky shore on the sea breeze. As you pass through the cool cave, the scenery of mysteriously shaped stones spreads out, giving you a feeling of exploration and reminiscent of the shallow waters of the sea about 16 million years ago. The seabed was raised by the Meiji Hamada Earthquake (1872), and the area is about 50,000 square meters. The characteristic thing that represents Tatamigaura is a rock called "nodule", in which calcium carbonate contained in the shell is solidified like concrete. There are also heart-shaped fossils "Happy Shell" scattered around. If you can find it, you will feel happy.
