The Tablelands make Gros Morne National Park important. It’s the largest bit of undisturbed, un-mined exposed mantle in the world. Most plants don’t really like to grow on the highly mineralized rock and it drains exceptionally quickly. It is basically a Martian landscape jutting out of the bogs and ancient glacial-carved valleys around it. I’ll have to do a bit more reading to actually remember how the mantle ended up on top of the crust, but it happened before Pangaea. That’s a long time ago.
