A strange explosion, a plume of black smoke, Canadian authorities dispatching aircraft to investigate: mysteries in the Arctic.
One grisly trace:
An Inuit member of the Canadian Rangers, a military reservist unit stationed in the far North, reported the incident, and said a hunter at the camp saw several dead whales on shore when he went over to investigate.
This isn't the first time weirdness has been noted there of late:
This past winter, a spectacular meteorite that swept across the sky lit up the radio waves with talk of UFOs.
Foreign submarines have also been sighted in Canadian Arctic waters over the past decade. No one will speculate on whether a submarine might be involved in this mystery blast.
"Until we hear from Parks Canada and the military, there's nothing we can confirm or deny," says Keith Pelley, a Fisheries and Oceans Canada official based in Nunavut.
Borden Peninsula is on the northern edge of Baffin Island.
