We also paddled much of Trout River Pond in Gros Morne. This fjord is remarkable in that it lies between the Tablelands to the north and the 1600' granite cliffs to the south. The tablelands are peridotite rock from the earths mantle deposited about 500M years ago when Africa and North America were still together. The granite cliffs contain enough silica and phosphorous to support much plant life. The Tablelands contain a lot of poisonous heavy metals, and too little other life supporting elements to support much plant growth. There are some carnivorous plants such as pitcher plants, that digest insects that sustain them.
