A rare black iceberg spotted off the coast of Labrador is making a splash on social media after a fish harvester living in Carbonear, N.L., took a photo of it while fishing for shrimp last month. "I have seen icebergs that are rolled, what they say have rolled in the beach with some rocks in it. The professor says the black iceberg might contain ice that's more than 100,000 years old. It would take a long time for that ground-up rock to spread so uniformly throughout the ice, Tarasov said.
