In this image, I’ve contrasted light to dark, small to large, rough to smooth, and, most likely, new to old. The boulder in the foreground seems to me to be the newcomer – the evening light has defined its texture for us, showing us that it is a boulder made up of many smaller parts. The boulder waiting in the darkness is much larger and smoother, and therefore probably the senior partner here. I am sure that a geologist could tell us much more about the comparative history of these huge rocks. But at very least, this image pulls even an uninformed eye over each of these surfaces, inviting the hand to touch and the mind to wonder about the millions of years it must have taken nature to create such a sight as this.
