This won't become a weekly series, because there's no guarantee that each week will proffer a startling discovery. But last week did.
On Saturday afternoon we drove along the river road towards Nerrigundah, the road that I walked in twelve instalments last year with such pleasure. We wanted to examine the rock in the cuttings with new geological eyes, and see if it matched any rockage we'd seen on the ridge in the morning.
We scrutinised the rock face in a way that never occurred to me twelve months ago, noting the easy way pieces peeled or broke off and fell to the road.
Then, high up, a riveting sight. Our first local fossil. Not a shell or a leaf – these rocks are too old for that. What we were looking at was ripples, that most evanescent of motion, captured in stone.
