This photo is a bit of a change of pace. This past weekend I was at the cottage (Garden Island, just outside of Kingston, Ontario) and was lucky enough to get pretty close to a Northern Water Snake that slithered over our swimming area. It later approached my girlfriend with a fish in his mouth as well…maybe it wanted to share? I dunno.

Of course, this wouldn’t be a photo of the week without geology so the rock that the snake is an Ordovician limestone that is part of the Black River Group. It is fairly fossiliferous and contains lots of large cephalopods and rugose corals.
