Cloud sea

When I reached the summit of Mt. Ege-san, it was very fine. And a wide cloud sea surrounded the summit. It was a great landscape.
During I was climbing, I thought it was mist. But, it was not mist, but a part of cloud. I climbed in the cloud.
Mountains were like island in the cloud sea.
Nobody staying under the cloud knows that it is very fine at the summit of mountain.
