This post is all full of mud as we'll explore the valley of mud volcanoes in the Crimea.
The very volcanoes are located in hollows, about half a kilometer in diameter. In the center of a hollow there is a round lake filled with mud.
On the surface of the lakes such vegetation grows.
One can step on them not drowning in the mud.
Pay attention to the footsteps. Of course, one is going to be full of mud while getting to the very volcanoes.
