[PAR] [TLE] Flathead Lake [SEP] Flathead Lake (Salish: člq̓etkʷ ) is the largest natural freshwater lake by surface area that is west of the Mississippi River in the contiguous United States, if one takes Red Lake and Lake of the Woods to be north of the Mississippi River, rather than west of the river. [PAR] [TLE] Rocky Mountain Trench [SEP] The Rocky Mountain Trench, also known as The Valley of a Thousand Peaks or simply the Trench, is a large valley in the northern part of the Rocky Mountains.  It is both visually and cartographically a striking physiographic feature extending approximately 1600 km from Flathead Lake, Montana to the Liard River, just south of the British Columbia-Yukon border near Watson Lake, Yukon.  The trench bottom is 3-16 km (2–10 miles) wide and ranges from 600-900 metres (2,000–3,000 feet) above sea level.  The general orientation of the Trench is an almost uniform 150/330 degree geographic north vector and has become convenient for north/south aviators.
