I think this is from sunlight passing through some glass on the car that was parked here. It just looked so solid lying there among the leaf mold and fallen twigs.
@seacreature It was weird. I had to put my glasses on and scrunch down there to see what was going on. Then I was afraid I'd miss the shot because as soon as the sun moves, it's gone and the dogs were tugging on the leads. Well, you know how that goes.
