Many rivers to cross!

As I've said before, this idea is taken from an item I first saw on Michael Brown's Macro Art in Nature website: Here Its a macro/close-up of agate section; taken with a tripod mounted Canon 400D and Tamron SP90 macro lens plus extension tubes. I'm really chuffed that Michael found time to pay Aperture Image a visit and comment on Crystalline
