Okay, my blogging skills aren’t all they could be — the verbiage didn’t show up with the photos.
The photos in the last post below were from Namafjall, a geothermal area in Northeast Iceland. Loved it! It was so unusual and exotic with steam rising here and there and bubbling mudpots. And stinky sulfur air. The hot springs produce sulfur deposits. The steam is caused by cold ground water seeping down into magma intrusions where it is heated, turned into steam and comes back to the surface. More than that I cannot say and hey, I’m on vacation so that’s as much brainwork as I can handle at the moment.
