Fort Good Hope lies along
Fort Good Hope lies along this river, which is located west of the Franklin mountains after passing by Wrigley. The Laird River joins it near Fort Simpson, and Richards Island is the largest island located near its delta, which lies to the west of Richardson Mountains and is bounded by Shoalwater Bay. It initially flows to the west, south of Horn Plateau, but turns north, running parallel to its namesake mountains eventually emptying into the Beaufort Sea. It originates at the Great Slave Lake, and is named for a man, who initially called it "Disappointment River" after navigating its course in 1789. For 10 points, name this longest river in Canada.
