Rocky hillside of Mt. Esan !

by Kazu

Is this scenery of plain a little  bit from that of lower level ?
It can be said that , I think.the flat area is in the crater of active volcano Esan.

It might be hard for plants to grow up enough in this area filled up with sulfur gas. The surface of the plain is comparatively hot.

In Germany, it is called "Karst", I think. There may be a huge cave under the ground as it is the typical structure of Kurst or young volcano..
