The Dungeon Provincial Park

The coastline and steep cliffs surrounding Cape Bonavista are spectacular examples of the North Atlantic Ocean’s wave action and erosive power. Unique shoreline features are due to the ancient sedimentary rocks’ composition and thousands of years of continuous coastal erosion.

The Dungeon had its origin as a cavern with two separate openings to the sea. Continuing erosion led to the widening of the cavern until eventually, the roof collapsed inwards. Wave action has slowly removed rock material from the collapse, leaving the incredible feature you now see. These collapsed sea caves are known as gloups. Due to the erosion from waves, storms, winds, and tides, the coastline is in a constant state of change, and one day the two arches will likely collapse. Can you predict which feature will be left behind? Observe the surrounding coastline towards Discovery’s geosite in Spillars Cove for a hint? The Dungeon will one day be a pillar of rock known as a sea stack.
