But at Gros Morne National Park, people can step on fragments of the mantle without having to dig an inch. On October 3, 2017, the Operational Land Imager (OLI) on Landsat 8 acquired natural-color imagery of Gros Morne National Park. Those mountains have since eroded and left behind the gneiss and granite peaks of the Long Range. The park contains some of the tallest peaks of the Long Range mountains, including Big Level and Gros Morne Mountain (French for “great somber”). Gros Morne National Park also features some recent geologic history at the Western Brook Pond.
