The snowcapped peak of Mount Rainier, which towers 4.3 kilometers (2.7 miles) above sea level in Washington state, has not produced a significant volcanic eruption in the past 1,000 years.
The volcanoes with historical eruptions include: Mount Rainier, Glacier Peak, Mount Baker, Mount Hood, Lassen Peak, and Mount Shasta. Renewed volcanic activity in the Cascade Arc, such as the 1980 eruption of Mount St. Helens , has offered a great deal of evidence about the structure of the Cascade Arc.
Rising above this volcanic platform are a few strikingly large volcanoes, like Mount Hood and Mount St. Helens, that dominate the landscape. [31] The Cascade volcanoes define the Pacific Northwest section of the Ring of Fire, an array of volcanoes that rim the Pacific Ocean. The Ring of Fire is also known for its frequent earthquakes.

[3] The park was established on March 2, 1899, as the fourth national park in the United States, preserving 236,381 acres (369.3 sq mi; 956.6 km 2) [1] including all of Mount Rainier, a 14,410-foot (4,390 m) stratovolcano.
Mount Rainier is central to Tacoma’s identity, so much so that it appears on the city’s logo. But as CNN recently reported, the striking mountain is also an active volcano — and no one knows ...

Mount Rainier is one of the most glaciated stratovolcanoes in the Cascade Volcanic Arc. Capable of setting off massive lahars, as evidenced in the valleys below it in all directions.
