...beautiful.
Looks like some of the places in Yellowstone.
Very nice article. Especially like the link to the following:
http://www.photovolcanica.com/VolcanoInfo/Erta%20Ale/Erta%20Ale.html
I had never heard of, nor read anything concerning, the Erta Ale volcano in Ethiopia, and was much interested to read about its phenomena.
Have you watched the series, On Volcanos of the World ? Fascinating double plus.
The series has been playing again recently. Discovery Channel I think.
This is one of the volcanos they feature. It’s in the middle of nowhere, very dangerous expedition.
Anyway, those pools are concentrated sulfuric acid.
