Cascade Volcanoes
What are the Cascade Volcanoes?
The Cascade Volcanoes form a chain more than 700 miles long, created by the Cascadia subduction zone off the Pacific coast. The arc contains nearly 20 major volcanoes among thousands of smaller vents. There is no single authoritative climbing list, so the count varies. Most lists include the large stratovolcanoes such as Mount Rainier, Mount Adams, Mount Hood, Mount Shasta and Lassen Peak, and some add lower or Canadian peaks like Mount Garibaldi. Mount Rainier is the highest at 14,411 feet. Mount St. Helens and Lassen Peak are the only two to have erupted in the 20th century.

Climbing the volcanoes of the Cascades
The Cascade Volcanoes stand apart from the ranges around them, so each climb is its own trip, often separated by hours of driving. Many are glaciated and have climbing seasons shaped by snow conditions. Climbers usually add them one or two a year. Yak keeps the whole chain in one place so you can see your progress from Lassen to Baker.
