I have been looking at your panorama and I feel each time more drawn into 
it. As a geologist, I am fascinated by those volcanic dykes that criss-cross 
the landscape. The absence of vegetation suggests to me a world from the 
Precambrian, lets say a billion years ago, before the emergence of life. I 
am not sure however, if then the sky was blue as there was no oxygen yet in 
the atmosphere. And the haze strongly suggests a carbon dioxide-rich 
atmosphere.
