Dungeon Provincial Park, Newfoundland and Labrador, Canada

Today's image takes us to Dungeon Provincial Park on the rugged coast of Newfoundland and Labrador, Canada, where nature tells a much older story.

Atlantic waves carved a sea cave with two openings, gradually widening it until the roof gave way.

What remains is a striking collapsed formation known as a 'gloup,' surrounded by steep cliffs and crashing surf.
