2. The Mountain Location Elevation Latitude:46.87 N Longitude:121.758 W
Mt. Rainer, Washington
Elevation
Towers 8,000 ft.
Mount Rainier is a stratovolcano / composite.
4,392 meters
(14,411 feet)

3. History and Hazards
Of Mount Rainier
Mount Rainier is covered with lots of ice and snow.
Its main cone of the stratovolano formed 730,000 years ago.
It is the third most volumious of the Cascade Range.

4. History & Hazards
Mount Rainier has a history of massive debris avalanches and debris flows.
A mudflow caused by steam explosions was one of the largest in the world.
Mount Rainier & other similar volcanoes in the Cascade Range erupt much less than Hawaiian volcanoes but, are more destructive.
ACTIVE VOLCANO

5. Geologic History
In the past 200 yrs. Mt. Rainier has had 2 eruptions in the year 1882.
Mt. Rainier creates its own weather.
It has 5 major rivers and tributaries that run through it.
Its cone is 9 miles long.

6. Cascade Range
This region is one of the most geologically young and tectonically active in North America.

7. The Carbon, Cowlitz, Emmons, and Nisqually Glaciers
Glaciers are among the most conspicuous and dynamic geologic features on Mount Rainier in Washington State.
For example, during the last ice age, from about 25,000 to about 15,000 years ago, glaciers covered most of the area now within the boundaries of Mount Rainier National Park and extended to the perimeter of the present Puget Sound Basin.
They erode the volcanic cone and are important sources of stream flow for several rivers .

8. Debris Flows, Mudflows, and Lahars
Debris flows are coarser and less cohesive than mudflows.
Lahar is an Indonesian word describing mudflows and debris flows that originate from the slopes of a volcano.
Debris Flows, Mudflows, and Lahars
Lahars are commonly initiated by:
large landslides of water-saturated debris,
heavy rainfall eroding volcanic deposits,
sudden melting of snow and ice near a volcanic vent by radiant heat or on the flanks of a volcano by pyroclastic flows, or
breakout of water from glaciers, crater lakes, or from lakes dammed by volcanic eruptions
