Receiving more than 100 in. (254 cm) of precipitation annually, much of it as snow, the Cascades are a major source of water in the NW United States. Hydroelectricity is generated on the western slope; irrigation is used in the fertile eastern side valleys. Timber is the region's chief resource, but a growing concern for ecology and the environment has developed into a major political debate surrounding the trees. The Cascade Tunnel, 8 mi (12.9 km), is one of the longest railroad tunnels in North America.

Cascade Range

 

a mountain range of the North American Cordillerra, located in the USA and Canada. Length, about 1,000 km; maximum altitude, 4, 392 m (Mount Rainier, a volcano).

The Cascade Range gets its name from the abundance of terrace-like waterfalls (cascades) on the Columbia, Fraser, Klamath, and other rivers that cut through the range. The range is formed by Mesozoic crystalline rocks covered by huge layers of Paleogene and Neocene lavas. Above this strongly dissected volcanic plateau, which is from 1, 800 to 2, 500 m high, rise isolated cones of volcanoes, such as Mount Baker, Mount Rainier, Mount Hood, and Lassen Peak, with altitudes of 3, 000 to 4, 000 m and more. Most of the volcanoes are extinct, although their slopes abound in fumaroles and hot springs. In the late 19th and early 20th centuries Mount Rainier and Lassen Peak showed their greatest volcanic activity. The volcanic peaks are covered with vast snow fields and glaciers. Dark coniferous forests grow on the humid western slopes of the range and pine trees on the dry eastern slopes; above 2, 800–3, 000 m, the forests give way to subalpine and alpine meadows. There are copper and gold deposits in the mountains. Crater Lake, Mount Rainier, and Lassen Volcanic national parks are located in the Cascade Range.
