From the World Heritage inscription:
Gros Morne National Park illustrates some of the world’s best examples of the process of plate tectonics. Within a relatively small area are classic, textbook examples of monumental earth-building and modifying forces that are unique in terms of their clarity, expression, and ease of access. The property presents the complete portrayal of the geological events that took place when the ancient continental margin of North America was modified by plate movement by emplacement of a large, relocated portion of oceanic crust and ocean floor sediments. The park also presents an outstanding demonstration of glaciation in an island setting. The fjords, waterfalls and geological structures of the park combine to produce a landscape of high scenic value.
Gros Morne is one of the hidden wonders of North America. It isn’t easy to get to but it it well worth the effort. The above photo is a fresh water fjord, which is one of the only one of its kind in the world.
