Great Slave Lake's East Arm is a world class scenic and geological wonder. Spectacular cliffs drop 180 metres into the tenth largest lake in the world. The scenery is primeval, the result of glaciation in North America and of a clearly visible fault in the earth's crust. This is the site of a future National Park, that includes an historic 50 km trail to the barrenlands called Pike's Portage. Outfitters offer sea kayak trips to the East Arm, and fishing packages, amid elemental scenery.
