They also form the northernmost section of the Appalachian chain on the eastern seaboard ofNorth America . In2003 it was announced that theInternational Appalachian Trail would be extended through the Long Range Mountains.Around 1,200 million years ago, in thePrecambrian era, the ancient core of what is now eastern North America collided slowly with another continent to form a vast mountain range. All that remains today are the deeply eroded granites and gneisses of the Long Range mountains.In late Precambrian time, the supercontinent began to break apart. As it split, steep fractures formed and filled with molten rock from below. This magma cooled into the diabase dykes seen in the cliffs of Western Brook Pond and Ten Mile Pond.
By 570 million years ago the continent finally rifted apart, and the resulting basin became an ocean called the
Iapetus Ocean . Some of the rocks of Gros Morne National Park were part of thecontinental margin on the western side of this new ocean, south of the Equator.Running along the
Gulf of St. Lawrence , the range comprises the following sections:*
Anguille Mountains ,
*Lewis Hills ,
* Tablelands (a section of the Earth's mantle exposed at the surface)
* main section of the Long Range Mountains (running northeast from the Tablelands throughGros Morne National Park , this is the only part of North America's east coast (south ofLabrador and not includingSomes Sound in Maine) that is indented byfjord s)Highest Peaks of the Long Range Mountains Rank Name m ft 1 The Cabox 814 2671 2 Gros Morne 807 2644 3 Blue Mountain 800 2625 4 Big Level 795 2608 5 Round Hill 763 2653 6 Rocky Harbour Hill 756 2480 7 Mount Saint Gregory 686 2251 8 Gros Paté 673 2208 9 Big Hill 659 2162 10 Old Crow 649 2129 References
