Many tourists will come to this region to get a view of the famous mountain with their telltale craters. This particular rock formation is the result of years of rain and wind blasting at the mountain and is older than the Andes itself.
The colours are so striking, especially against the brown Andes in the background, with the green vegetation in the valley which is just out of shot in this pic.
Beautiful and never seen
I would be happy to show you around if you made it to Atacama.
