Depth of crater

When I reached opposite side of crater, the mist reduced. And I could see the depth of crater. It was very very happy. If I could't see it, I could't realize that I walked around the crater. It was a good memory.
There was a small pond at the depth. And it was covered by green on the ground.
It looked easy that it was easy to walk down to the depth. But, there was no road on the map. So, I imagined that there would be a poison around there. So, I abandoned to do it.
