Long Range, mountain range, extending c.300 mi (480 km) along the west coast of Newfoundland island, Canada; rises to 2,672 ft (814 m) in the Lewis Hills. It forms the Great Northern Peninsula of NW Newfoundland. Part of the Appalachian system, the range consists of parallel ridges that rise steeply from the coast and slope gently eastward. A depression, of which Grand Lake and St. George's Bay are part, divides Long Range into two sections. The densely forested range is economically important for timber. Gros Morne National Park is there.
