Cascade Range : New Research
New research reveals that long-dormant volcanoes in the Cascades region of the Pacific Northwest still have substantial magma reservoirs beneath them.
- Cascade Range is a prominent collection of mountains found in the Pacific Northwest area of the northwestern United States and southwestern Canada.
- The range was formed by the subduction of the Juan de Fuca Plate beneath the North American Plate, which continues to drive volcanic activity.
- It is known for its snow-capped peaks, massive glaciers, steep scree slopes, and lush forests.
- The range is home to 4375 named mountains, the highest and most visible of which is Mount Rainier 4,392 m.
- It includes both volcanic and non-volcanic mountains, including the rugged spires of the North Cascades, and the notable volcanoes known as the High Cascades.
- The Cascades are part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean.
- All of the known historic eruptions in the contiguous United States have been from Cascade volcanoes.
