Found this on my doorstep this morning. It appears to be a caribou leg. All the tracks around it are mine, so I don't know if a person put it there, or a dog dragged it over, or it just fell from the sky at some point in the night.
Perhaps it's some sort of threat from a tundra-based mafia? (tonight, you sleep with the caribou) I have to say that the thought of it falling from the sky, dropped by who knows what, seems the creepiest option at the moment.
