Mount Rainier is a massive stratovolcano located 54 miles southeast of Seattle in the state of Washington, United States. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 feet.
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 would threaten the whole Puyallup River valley.
"The mountain was originally named Tahoma or "Great Snowy Peak" by the Yakima Indians. Captain George Vancouver renamed it after Admiral Peter Rainier of the British Navy during a scouting expedition on May 7, 1792. This name was hotly contested for over 100 years, because Americans felt it shouldn't be named after a British officer who had never even been to the U.S."
