Fumaroles are cracks and holes in craters and slopes of a vulcano from which vulcanic gases come out. To have a look at fumarole glade of Mutnovsky volcano in Kamchatka one has to climb its extreme steep slopes.
Because of the high sulphur concentration all the hills have a tint of yellow and red.
The wind drives volcanic gases down the gorge and creates such fog.
From far away the source of smoke can be seen. Volcanic gases rise above the streams flowing from the icicle.
The last climb and here it is – fumarole glade.
One can even come up to these wonderful creations. But don’t come too close as the gases carry high concentration of sulphur.
