The photographer who captured a rare black iceberg off the coast of Labrador says he’s never seen anything like it.

Hallur Antoniussen is originally from the Faroe Islands, but has been living in Carbonear for the last 30 years.

He’s spent half a century at sea and while he’s seen icebergs with rocks and other debris in them, he’s never seen anything like it.

He says someone suggested that dark colour could be as the result of volcanic ash from some ancient eruption, but no-one has been able to confirm that for him. But that’s not the only thing that makes it stand out, “it’s bigger on the top than it is on the bottom,” says Antoniussen, “I’ve never seen the shape really of an iceberg like that.”
