Gros Morne National Park

Gros Morne National Park

Situated on the west coast of the island of Newfoundland, 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. More recent glacial action has resulted in some spectacular scenery, with coastal lowland, alpine plateau, fjords, glacial valleys, sheer cliffs, waterfalls and many pristine lakes.

Parc national du Gros-Morne

Situé sur la côte ouest de l'île de Terre-Neuve, le parc offre un exemple rare de l'évolution de la dérive des continents où la croûte océanique profonde et les rochers du manteau terrestre sont exposés. L'action glaciaire plus récente a sculpté un paysage spectaculaire composé de basses terres côtières, de plateaux alpins, de fjords, de vallées glaciaires, de falaises abruptes, de chutes et de plusieurs lacs inviolés.

منتزه غرو مورن الوطني

يقع هذا المنتزه على ضفاف الساحل الغربي لجزيرة نيوفاوندلاند الكندية، وهو يعطي مثالاً نادراً عن تطوّر طفو القارّات حيث تبرز القشرة المحيطية العميقة وصخور أديم الأرض. ثم رسمت الحركة الجليدية معالم منظر طبيعي رائع يتألف من أراضٍ ساحلية منخفضة وهضاب ألبية وأزقة بحرية وأودية جليدية وجروف وعرة وشلالات والعديد من البحيرات التي لا تزال في حالتها البدائية.

Национальный парк Грос-Морн

Парк, располагающийся на западном побережье острова Ньюфаундленд, предоставляет редкую возможность изучения дрейфа континентов, поскольку именно здесь выходят на поверхность породы, вынесенные некогда из мантии Земли и из океанической земной коры. Последнее оледенение сформировало здесь оригинальный рельеф – это прибрежные низины, альпийские плато, фьорды, выработанные ледником горные долины, крутые утесы, водопады и множество чистейших озер.

Parque Nacional de Gros-Morne

Situado en la costa occidental de la provincia de Terranova, este parque presenta afloramientos de la corteza oceí¡nica profunda y de rocas del manto terrí¡queo, que ofrecen un ejemplo excepcional de la deriva continental. Las glaciaciones mí¡s recientes han modelado un paisaje espectacular formado por tierras bajas costeras, mesetas alpinas, fiordos, valles glaciares, farallones abruptos, cascadas y numerosos lagos impolutos.

Nationaal park Gros Morne

Het nationaal park Gros Morne ligt aan de westkust van het eiland Newfoundland. Het park is een zeldzaam voorbeeld van het proces van continentale drift, waarbij diepe oceaankorst en rotsen van de aardmantel blootliggen. Meer recente glaciale activiteit heeft een spectaculair landschap gevormd, met laaggelegen kustgebieden, hoogvlaktes, fjorden, gletsjervalleien, steile kliffen, watervallen en veel ongerepte meren. In het gebied zijn ook fjorden en watervallen te vinden. Het park bestaat uit een deel van de Long Range Mountains in de Golf van Saint Lawrence. Langs de kustlijn zijn stranden, steile kliffen en duinformaties tot 30 meter hoog te vinden.

Gros Morne National Park
Statement of Significance

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.

Criterion (vii): Gros Morne National Park, an outstanding wilderness environment of spectacular landlocked, freshwater fjords and glacier-scoured headlands in an ocean setting, is an area of exceptional natural beauty.

Criterion (viii): The rocks of Gros Morne National Park collectively present an internationally significant illustration of the process of continental drift along the eastern coast of North America and contribute greatly to the body of knowledge and understanding of plate tectonics and the geological evolution of ancient mountain belts. In glacier-scoured highlands and spectacular fjords, glaciation has made visible the park’s many geological features.

Long Description

Located on the western shore of the Great Northern Peninsula of Newfoundland, 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. More recent glacial action has resulted in some spectacular scenery, with coastal lowland, alpine plateau, fjords, glacial valleys, sheer cliffs, waterfalls and many pristine lakes.

The park comprises part of the Long Range Mountains on the Gulf of St Lawrence. The park includes coastal lowlands and an alpine plateau. The marine areas included in the park covers the inner portion of St Paul's Inlet, intertidal zones and estuaries. The shoreline features beaches, steep cliffs, and dune formations up to 30 m in height.

An upland alpine plateau with perched lakes, bare rock and valleys, covers a large proportion of the eastern central park. The serpentine hills in the south-west comprise ultra-basic igneous rocks, which, due to high heavy metal content, inhibit most plant life. A number of steep sided, glacial valleys cut through the Long Range scarp face, forming deep, oligotrophic fjords, with vertical cliffs up to 685 m high. A number of waterfalls are fed in the summer by snow-melt at higher altitudes.

The park is geologically diverse with areas of Ordovician sedimentary rocks, Precambrian granite and gneiss, Palaeozoic serpentinized ultra-basic rocks, gabbros, volcanic and Lower Palaeozoic sedimentary rocks. Exposed oceanic crust, mantle, a section of ancient Mohorovicic discontinuity, and other distinctive geological features are also found. There is also an unusually complete palaeotological sequence which has been proposed as the world stratotype for the Cambrian-Ordovician boundary.

There are up to 36 distinct vegetation types and communities, with some vascular species and bryophytes, representing about 60% of Newfoundland's insular flora.

The coast includes typical shoreline communities, active dunes with white spruce, and cliffs with prostrate spruce and balsam fir. The coastal plain further inland has a number of plant communities including a mosaic of sedges in meadows with American larch scrub. Black spruce dominates wet, oligotrophic sites and balsam fir is found in more protected and mesic areas. Tundra vegetation has developed on the plateau above this and varies from small areas of coniferous forest and stunted forest to bare rock.

Faunal diversity resembles an oceanic rather than continental-shelf island and is markedly reduced compared with the mainland. However a number of species scarce in Canada are found, including lynx, caribou and arctic hare. The more common marine mammals that can be observed from the park, albeit with a diminishing frequency in recent years include pilot, minke and finback whales and harbour seals.

The avifauna comprises arctic, boreal and pelagic species, with strays from mainland, the north-west Atlantic and Europe. The park is a significant breeding site for harlequin duck, blackpoll warbler, common tern and arctic tern, a nesting site for bald eagle, rock ptarmigan and American tree sparrow, and a stopover for migrating shore birds.

Anadromous Atlantic salmon and arctic char are found in park waters and also in permanent freshwater form in certain landlocked lakes on the Long Range Mountains.

There are a number of archaeological sites in the park and human habitation can be traced back to the Maritime Archaic Indians (4,500-3,000 years ago) and the Dorset Eskimos (1,800-1,200 years ago). Europeans settled the area from the late 18th century.

Historical Description

Established under a Federal/Provincial Agreement signed by the Governments of Canada and Newfoundland and Labradc on 13 August 1973. The same authorities amended this agreement on 18 May 1983, whereby approximately 9,300ha were returned to the province. The park is currently being formally established under the National Parks Act (Parks Canada, 1986). Inscribed on the World Heritage List in 1987.
