In early May 1792, British Navy Officer and Explorer, George Vancouver, named Washington State’s
tallest structure in honor of his friend, Rear Admiral Peter Rainier.
While stunningly beautiful and seemingly serene, Mt. Rainier is considered one of the most dangerous
volcanoes in the world, being near major metropolitan areas including Tacoma. Because of its large
amount of glacial ice, Mt. Rainier could produce massive lahars that could threaten the entire Puyallup
The broad top of Mount Rainier contains three named summits. The highest is called the Columbia Crest,
standing at 14,411 feet, making it the tallest structure in Washington State and the Cascade Range.
The most recent recorded volcanic eruption was between 1820 and 1854, but many eyewitnesses
reported eruptive activity in 1858, 1870, 1879, 1882, and 1894 as well.
About 8,000 to 13,000 people attempt to climb to the summit each year, with only about a 50% success
