![]() It includes peaks that run down the western coast of the Americas from the volcanoes of the Aleutians in Alaska to those of the Andes in Chile. The Ring of Fire is a system of volcanoes that extends around much of the rim of the Pacific Ocean. These volcanoes are part of a greater volcanic region called the Cascade Volcanic Arc, which itself is a part of the Ring of Fire. The Cascade Range is a particularly interesting range from a geologic perspective as it is home to a number of active volcanoes The Washington section of the range is situated in Skamania, Clark, Cowlitz, Lewis, Pierce, Thurston, King, Snohomish, Skagit, and Whatcom counties while the British Columbia portion of the Cascades is located in the Fraser Valley, Okanagan-Similkameen, and Squamish-Lillooet regional districts. In California, the range is located in Shasta, Lassen, and Siskiyou counties, and in Oregon, the range is part of Jackson, Klamath, Douglas, Lane, Deschutes, Jefferson, Linn, Marion, Wasco, Clackamas, Hood River, Wasco, and Multnomah counties. The Cascades encompass part of three US states and one Canadian province: California, Oregon, Washington, and British Columbia. They are also situated to the west and northwest of the Columbia Mountains, Columbia Plateau, Sierra Nevada, and Great Basin Ranges as well as to the south and southwest of the British Columbia Interior and the Canadian Rockies. ![]() In fact, the range is surrounded by mountain ranges and plateaus on nearly all sides.įor example, the Cascades are located to the east of the Pacific Coast Ranges ( Northwest US Coast Ranges), which include the Olympic Mountains, Klamath Mountains, and the Pacific Ranges. That said, the Cascades are far from the only mountain range in the region. In fact, some of the peaks in the Cascades, such as Mount Baker, are known to receive dozens of feet of snow each winter. Their proximity to the Pacific Ocean and the fact that the region has prevailing westerly winds is also one of the reasons why the range receives so much snow and rain each year. The Cascades are one of the most rugged mountain ranges in the northwestern US. The range then stretches northward through Oregon and Washington until its terminus, which is located at the confluence of the Thompson and Nicola rivers in the southern part of the Canadian province of British Columbia.įor the most part, the Cascade Range coincides with the southern and central part of the Cascade Volcanic Arc, which includes the volcanoes that formed as a result of the Cascadia subduction zone. Most sources pinpoint the southern terminus of the Cascades as Lassen Peak, which is a lava dome that’s located in northern California. In total, the range extends for some 700 mi (1,100 km) from north to south and is upward of 80 mi (130 km) wide at its widest point. The Cascade Range (more commonly referred to as just ‘the Cascades’) is one of the major mountain ranges in the western United States.
