Of all the mighty volcanoes of the Cascade Range, extending from southern British Columbia through northern California, none dominate the horizon as does Mt. Rainier. Rising from the Cascade foothills of central Washington, Rainier easily is the tallest of the High Cascade peaks. At 14,411 feet, Rainier is almost 300 feet higher than Shasta, the only other Cascade volcano exceeding 13,000 feet. On the other hand, as impressive as it is, Rainier is only one of more than 400 volcanoes that comprise the Ring of Fire that encircles the Pacific Ocean.
