Cascade Mountains


The Cascade Mountains is a range extending over 1,120 kilometers (700 miles) in the northwest United States from northern California, through Oregon and Washington to British Columbia. Its highest peaks are Mount Rainier (4,392 meters, 14,409 feet), Mount Adams (3,742 meters, 12,277 feet), Mount Baker (3,285 meters, 10,777 feet), and Mount Hood (3,424 meters, 11,233 feet). The region is tectonically active – a fact spectacularly demonstrated by the 1980 eruption of Mount St Helens – and riven by faults.


The phenomenon known as earthlights, believed to be associated with faults, has been seen close to the location where Kenneth Arnold reported the first "flying saucers" in 1947, suggesting a possible link.
