	Rocky Mountain Trench
		Rocky Mountain Trench is a great valley extending 1400 km NW through BC from Montana to the Liard Plain just S of the Yukon Territory.
		The trench is mainly demarcated by the wall-like slopes of major mountain ranges - the ROCKY MTS on the E and the COLUMBIA, Omineca and CASSIAR mountains on the W. The northern half of the trench is very straight and trends more northerly than the southern half, which is slightly sinuous to arcuate.
		The trench is bordered along much of its length by faults and is an ancient zone of crustal weakness, perhaps a former continental margin.

	Geology and History of Flathead lake
		About 150 million years ago, the Rocky Mountains began to rise with an uplifting of sedimentary bedrock that formed the mountains present in the Flathead watershed today.
		Geologists call it the Rocky Mountain trench and the Flathead and Mission Valleys are its southernmost end.
		Ice poured off the neighboring mountains and down their valleys as smaller glaciers that met and coalesced in the Rocky Mountain trench.

		The first two centuries of life in the Rocky MountainTrench must have been difficult indeed, and it is not surprising that the Sekani continued to dream of their old homes on the lower Peace River, where buffalo, deer, moose, and beaver were plentiful.
