One of the many things I adore about rock is the way it offers such a joyous sense of perspective. When I realize what a tiny blip in geological history I am, most of my troubles start to look pretty pathetic. After all, even the entire history of mankind will one day be reduced to a small brown stain in a few cliff faces. And yet, at the very same time, rocks make me feel wonderfully connected to everything that is and ever was, and I become acutely aware of the meaningful part I play in this huge and beautiful story. It’s quite paradoxical.
The other day I needed to go out for a walk to do some thinking about the brain, so I decided to stroll along the Lake Mary Fault, a few miles from my apartment. Lake Mary lies in a Graben – a block of the earth’s crust that has slumped downwards between two faults. The fault line itself is pretty dull to look at and yet, as my mother often used to reassure me, looks aren’t everything.
