词条 | Peace River |
释义 | Peace River river, Canada ![]() ![]() The river, named for Peace Point, Alta., where the Cree and Beaver Indians settled their territorial dispute, became an important fur-trade route after it was explored by Sir Alexander Mackenzie (Mackenzie, Sir Alexander) (1792–93). Farming, the valley's economic mainstay during the early decades of the 20th century, is now supplemented by lumber, coal, petroleum, and natural gas. In 1967 the W.A.C. Bennett Dam (600 feet 【190 m】 high and 1.25 miles 【2 km】 long) near Hudson's Hope, B.C., was completed, creating Williston Lake and providing the valley with hydroelectric power and flood control. The Peace is navigable from the town of Peace River, Alta., to the Slave, except for a stretch of falls near Fort Vermilion. |
