This may take some time.

So - you see the stripey layers in the mountain behind the one with the climber, and indeed into the distance. You will know from year 10 science, this tells us that the rocks were originally laid down under water, probably a sea bed - yonks ago. On a vast scale, they have been tumbled about and they find themselves at quite some height.

So long, so much time. Of no remark to many and no relevance to day to day life, this never ceases to amaze me.
