Deadly sounds right, hehe. And for the colors, I guess that there was too much vapor to see them at the moment, perhaps?

I've been between igneous petrology, mineralogy, and environmental sciences. My focus is quite unfocused, haha. I haven't met @nineclaws yet.

It's nice to have some context about the geology of the great outdoors, but not knowing much won't interfere with the enjoyment.

A pleasure to read your posts :)
