About Námaskarð
Situated on the north side of Iceland's Lake Myvatn, this geothermal wonder of hot sulfuric mud springs and steam springs (solfataras and fumaroles if you're a geology nerd) is otherworldly. Black rivers and bubbling pools of sulfuric mud cut through a landscape that's rich with colorful minerals and is continuously steaming.
Námaskarð is a magnificent example of how strange and "unearthly" our planet's natural landscapes can be, and just how pungent they can be as well.
The large fumarole in the hill at Monument Geyser Basin. I was trying to figure out what may have happened with the rocks tossed about. Was there a steam explosion? It didn't look like the rocks simply slipped down the hill. Yet the fumarole is very large and clearly has a lot of energy.
Krafla is a caldera of about 10 km in diameter with a 90 km long fissure zone, in the north of Iceland in the Mývatn region. Its highest peak reaches up to 818 m and it is 2 km in depth. There have been 29 reported eruptions in recorded history.
South of the Krafla area, but not actually within the caldera is Námafjall, a mountain, beneath which is Hverir, a geothermal area with boiling mudpools and steaming fumaroles.

Hot springs are sites where groundwater emerges at the Earth’s surface (or on the seafloor). Hot spring water has to be higher in temperature than the human body (an admittedly arbitrary definition): over 98° Fahrenheit or over 37° Celsius. Geysers are hot springs that episodically erupt columns of water. The highest concentration of geysers and hot springs anywhere is at the Yellowstone Hotspot Volcano in northwestern Wyoming, USA.
Beryl Spring is located in the Gibbon Canyon Group of Yellowstone’s Gibbon Geyser Basin. It has hot, aquamarine-colored water, hence the name “Beryl” (aquamarine is a bluish, gem-quality variety of the mineral beryl, Be3Al2Si6O18 - beryllium aluminosilicate). The pool has constant, energetic roiling and boiling, accompanied by significant overflow in a well-developed runoff channel. Behind Beryl Spring is a prominent, noisy fumarole that has been given the catalog designation GGCGNN073. Fumaroles are hot steam vents.
One last view of Lassen Volcanic National Park, looking up toward Brokeoff Mountain where steam pours from a fumarole. I liked this national park. It ranks pretty high on my list.
That's it for national parks for a while ... at least new national parks. I've revisited two parks since I took this picture, but I don't know when I'll see my next new park. I only have 16 to go, and I've seen all the easy ones.
