Mount Rainier
Mount Rainier (pronounced: /reɪˈnɪər/), Mount Tacoma, or Mount Tahoma is the highest mountain of the Cascade Range of the Pacific Northwest, and the highest mountain in the state of Washington. It is a large active stratovolcano located 54 miles (87 km) south-southeast of Seattle. 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. Rainier could potentially produce massive lahars that could threaten the entire Puyallup River valley.
