Experts, such as volcanologists, geologists, and climate scientists agree that Mt. Mount Rainier, highest mountain (14,410 feet [4,392 meters]) in the state of Washington, U.S., and in the Cascade Range.  Statistics place the likelihood of a major eruption in the Cascade Range at 2–3 per century.  Efforts are also being made to reintroduce native species that had locally been hunted to extinction, like the Pacific fisher. Routes are graded in NCCS Alpine Climbing format. Tacoma, at the mouth of the Puyallup, is only 37 mi (60 km) west of Rainier, and moderately sized towns such as Puyallup and Orting are only 27 and 20 mi (43 and 32 km) away, respectively. View Images An aerial view shows the Seattle harbor with Mount Rainier in the background. , The size of glaciers on Mount Rainier has fluctuated significantly in the past. , In one of the worst disasters on the mountain in over thirty years, six climbers—two guides, and four clients—last heard from on May 28, 2014, were presumed dead on May 31, 2014, when low-flying search helicopters pinged the signals from the avalanche beacons worn by the climbers. The early lavas formed a "proto-Rainier" or an ancestral cone prior to the present-day cone. , After the 2015 restoration of the original name Denali from Mount McKinley in Alaska, debate over Mount Rainier's name intensified. It is quite prominent topographically and it … On March 2, 1899, President William McKinley established Mount Rainier National Park as America's fifth national park.

Willi Unsoeld, who reached the summit of Mount Everest in 1963, was killed, along with an Evergreen College student, in an avalanche on Mount Rainier in 1979.  An eruption could be deadly for all living in areas within the immediate vicinity of the volcano and an eruption would also cause trouble from Vancouver, British Columbia, Canada to San Francisco, California because of the massive amounts of ash blasting out of the volcano into the atmosphere.
