Green Point and was our view in back of our campsite

At 10:00 we went to Green Point to hear a geology lecture. Chris Rohrback gave the talk, and she was great. She has a way of making a difficult subject simpler and fun. It is the eroded remnants of a mountain range formed 1.2 billion years ago. “The park provides a rare example of the process of continental drift, where deep ocean crust and the rocks of the earth’s mantle lie exposed.” (Centre, UNESCO World Heritage).
Gros Morne became a national park 1973, but it was for the geological studies that it was named a UNESCO World Heritage Site. The complex nature of a tremendous upheaval a billion years ago made for a lifetime study by Robert Stevens and Harold Williams, who established the concept of tectonic plate movement.
This site offers a unique, exposed view of the plates turned vertical so you can readily see all the layers. Chris explained how the world was one supercontinent, before Africa and Europe pulled away, drifting to the east, leaving parts of Africa and Spain along the east coast of Newfoundland. Parts of these Appalachian Mountains went with Europe and can still be seen today.
These mountains were the size of the Himalayas. Thousands of years of erosion have reduced their size, and glaciers gouged out U-shaped valleys, pushing boulders all the way to the ocean and this beach. There are layers of sediment, shale (compacted mud), limestone, soapstone and whatever the other one was. “Here geologists discovered fossils that define the boundary between the Cambrian and Ordovician periods and makes Green Point a world geological benchmark.” (https://www.pc.gc.ca/en/pn-np/nl/grosmorne/activ/decouverte-tours/gp)
Once a thriving fishing village, there are many restrictions today.
