We were in awe. Green Point, in Gros Morne National Park, is one of the few places on earth where the Cambrian and Ordovician rock boundary is easily seen, and confirmed via carbon dating and fossils present.
"In 2000, the cliffs at Green Point were approved as the Global Stratotype Section and Point for the base of the Ordovician system by the International Union of Geological Sciences. The boundary is a section 60m thick composed of layers of shale and limestone with overturned beds dipping 60-70 degrees to the South East. It is marked by the first appearance of Iapetognathus fluctivagus, a conodont fossil, 4.8m below the earliest known planktic graptolite fossil, Rhabdinopora praeparabola.
The shales represent a 30 million year record of deep-ocean sediments laid in a base-of-slope environment in the Iapetus Ocean. The limestone layers indicate periodic avalanches from the shallower waters. Portions of the same limestone avalanches that came rest to further up the coastal slopes are featured at Cow Head. There, the individual rocks in the limestone conglomerate are much larger."
Look straight across the cove and you can see where the two period sidle up to each other.
I don't know what makes these rocks do this wavy thing, but am going to find out.
