Gros Morne National Park of Canada was designated a UNESCO World Heritage Site in 1987. The park is an area of great natural beauty with a rich variety of scenery, widlife, and recreational activities. Visitors can hike through wild, uninhabited mountains and camp by the sea. Boat tours bring visitors under the towering cliffs of a freshwater fjord carved out by glaciers.[3]

Gros Morne National Park is a world heritage site located on the west coast of Newfoundland. At 1,805 km2 (697 sq mi) , it is the second largest national park in Atlantic Canada (surpassed by the Torngat Mountains National Park Reserve at 9,600 km2/3,700 sq mi).

The park takes its name from Newfoundland's second-highest mountain peak (at 2,644 ft/806 m) located within the park. Its French meaning is "large mountain standing alone," or more literally "great sombre." Gros Morne is a member of the Long Range Mountains, an outlying range of the Appalachian Mountains, stretching the length of the island's west coast. 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."

The Gros Morne National Park Reserve was established in 1973. It wasn't until October 1, 2005 that the National Parks Act was applied to the reserve, thereby making it a Canadian National Park.


The park's rock formations, made famous by Robert Stevens and Harold Williams, include oceanic crust and mantle rock exposed by the obduction process of plate tectonics, as well as sedimentary rock formed during the Ordovician Period, granite from the Precambrian and igneous rocks from the Palaeozoic Era.

The many soil associations mapped in the park reflect the wide variety of bedrock. The Silver Mountain soil association, dominant in the northeastern area, is a very stony sandy loam developed on glacial till overlying granite, granitic gneiss and schist. Similar rocks underlie the St. Paul's Inlet association farther west. Sedimentary rocks (including some dolomitic limestone) in the southeastern sector support the North Lake association of stony sandy loam. An association of mostly-shallow loam, the Cox's Cove, occupies a discontinuous band over shale, slate, limestone and sandstone near the coast. The coastal strip north of Bonne Bay is mostly underlain by the peaty Gull's Marsh association and the coarse Sally's Cove association except for an area of clay (Wood's Island association) around Rocky Harbour. The stony infertile soils of the ultramafic tablelands south of Bonne Bay belong to the Serpentine Range association

Around 1,200 million years ago, in the Precambrian 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 the continental margin on the western side of this new ocean, south of the Equator

Over the next 100 million years, during the Cambrian and Ordovician periods, ancient North America and what is now Gros Morne National Park drifted northward. Sediment eroding from the North American continent washed into the Iapetus Ocean and accumulated offshore as a broad continental shelf.

The first sediments were sands and silts deposited in shallow water. These sediments are now the quartzites that cap Gros Morne Mountain and directly overlie the ancient granites and gneisses. Sediment supply decreased, and carbonate banks flourished in the shallow tropical waters as the calcareous remains of snails, brachiopods, trilobites and algal mats accumulated. These remains of ancient organisms form the park's extensive sequences of limestone and dolomite.
Near the edge of this ancient tropical shelf, currents caused some sediment to be deposited into deeper water as debris flows. This material washed down the continental slope and formed coarse sandstone. Occasionally, overloading, by earthquakes or by storms triggered submarine landslides. These landslides toppled thousands of tonnes of limestone from the edge of the continental shelf and deposited the rubble on the continental slope. Eventually this rubble cemented together to form limestone breccia (a type of conglomerate) and shales.

The dramatic events that created the varied bedrock types of Gros Morne National Park are not the end of the area's geological story. Continental collision continued for 100 million years as the Appalachian Mountains grew. The rocks of the park were folded, faulted, and uplifted during the Devonian by widespread movements in the Earth's crust.
Since the Devonian the rock assemblage of the park has remained relatively stable except for erosion, uplift and some slight shifting along faults. The last two-million years of repeated glaciation, deglaciation, and associated sea-level changes shaped the park scenery that we see today.[4]
