Lisa points to a recessed leaf vein in a rock. A white overlay highlights the subtle structure.

Richard: Nice, and below that, there’s a bit of a log, there. You see the wood impressions.

Below the leaf, wood grain impressions run along the surface of the rock. A white overlay traces out these lines made from the wood.
