Mount Rainier [a] (/ r eɪ ˈ n ɪər / ray-NEER), also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. [9]
Mount Rainier, a snowcapped volcano, looms over Puyallup Valley near Orting, Washington. The prospect of a lahar — a swiftly moving debris flow caused by melting snow and ice typically during a ...
Mount Rainier National Park is a national park of the United States located in southeast Pierce County and northeast Lewis County in Washington state. [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.
All are active volcanoes. [73] Mount Rainier—the tallest mountain in the state [74] —is 50 miles (80 km) south of the city of Seattle, from which it is prominently visible. The United States Geological Survey considers 14,411-foot-tall (4,392 m) Mount Rainier the most dangerous volcano in the Cascade Range, due to its proximity to the ...
The Mount Rainier Volcano Lahar Warning System consists of two separate components, operating in tandem: Acoustic Flow Monitors (AFM) and the All Hazard Alert Broadcast (AHAB) sirens. The AFM system was developed by the United States Geological Survey (USGS) in 1998 and is now maintained by Pierce County Emergency Management.
Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform among volcanologists. The level of activity of most volcanoes falls upon a graduated spectrum, with much overlap between categories, and does not always fit neatly into only one of these three separate categories.
From locations in northern Seattle and northward, Glacier Peak is closer than the more famous Mount Rainier (Tahoma), but as Glacier Peak is set farther into the Cascades and almost 4,000 feet (1,200 m) shorter, it is much less noticeable than Mount Rainier. Glacier Peak is one of the most active of Washington's volcanoes.
While teaching at a school in Yelm, Washington, Fay Fuller and her class were visited by P. B. Van Trump who inspired Fuller to summit Mt. Rainier herself. [19] In 1890, after a failed attempt in 1887, Fuller was invited by P.B. Van Trump to join a climbing party and attempt to summit Rainier for a second time. [ 19 ]
