Cool video! Shame they don't show any of the "mud bath" ones though.
Warm volcanic mud would be an awesome experience. Not so much the 200+ degrees Farenheight ones though!
Isn't there a hot pool in Yellowstone people are told to stay out of, but every now and then someone ignores the rules, and gets disolved by the hot acidic water?
I visited a few of those mud volcanoes in Azerbaijan; amazing sights, but the mud coming from the smaller ones I went to was FREEZING (I stuck my finger in one).
Plus you do get the super hot ones, which I wouldn't go near...
