It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m).Mt. Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list.Because of its large amount of glacial ice, Mt.
