The Tablelands, found between the towns of Trout River and Woody Point in south west of Gros Morne National Park, look more like a barren desert than traditional Newfoundland. This is due to the ultramafic rock – peridotite – which makes up the Tablelands. It is thought to originate in the Earth’s mantle and was forced up from the depths during a plate collision several hundred million years ago. Peridotite lacks the usual nutrients required to sustain most plant life, hence its barren appearance. The rock is very low in calcium, very high in magnesium, and has toxic amounts of heavy metals. Peridotite is also high in iron, which accounts for its brownish colour (rusted colour). Underneath this weathered zone, the rock is really a dark green colour.
4 km return easy trail is a good starting point to your exploration of Gros Morne National Park. The main trail follows an old roadbed as it skirts the base of the mountain. Geology here marks a time when the continents of Africa and North America Collided, pushing these rocks, originally beneath the ocean, to their present position on land. Discover this unique area through the daily(summertime) guided walks that Parks Canada provides. You can take a walk guided by parks employees or download their app and follow the path on your own, either way is wonderful. Come enjoy the beauty that Tablelands has to offer.
