At the foothills of this spectacular volcanic mountain is an expanse of hot springs called Hverir that are known for their changing variety. You may also find a number of fumaroles, mud pools and mud pots that all seem to be boiling with relentless energy. The pass Námaskarð is strategically located at a short distance from the Krafla volcano system. The other thing that is sure to strike you about Námaskarð is the sheer lack of vegetation. However, if you give a thought to the high-temperature range, it does not appear an impossibility altogether. The constant emission of the fumes has made the ground utterly sterile and acidic, unfit to sustain any floras and faunas. You must bear in mind that the fumes can be harmful to humans as well.
