Ryūgu Gorge

Ryūgu Gorge [让口水汕 りゅうぐ・すいた] is a gorge located on the Usamizu River in Heisai Prefecture. It is due north of the largest city, Yukigata, and south of Genzu. It is a narrow chasm cut through rock by the flow of the Usamizu. The name of the gorge translates to 'mouth of the dragon'; aptly, the sheer cliffs lining the gorge are made of basalt columns, which, as the stone has twisted and flowed over time, have to come to resemble dragon scales.
There is a small temple located nearby called Ryūgumizu Temple.
