What is Mount Rainier called now?


Mount Rainier (/reɪˈnɪər/), also known as Tahoma, Tacoma, Tacobet, or təqʷubəʔ, is a large active stratovolcano in the Cascade Range of the Pacific Northwest, located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle.

What tectonic plates created Mount Rainier?

Mount Rainier (Figure 2.1) is one of about two dozen recently active volcanoes in the Cascade Range, a volcanic arc formed by subduction of the Juan de Fuca plate beneath the North American plate.

What igneous rock is associated with Mount Rainier?

Mount Rainier is chiefly made of andesite and some dacite lava flows and has erupted sizeable amounts of pumice throughout its history, though not as voluminously or as frequently as Mount St. Helens.

What type of volcano is this one Mount Rainier WA?


Mount Rainier is an episodically active composite volcano, also called a stratovolcano. Volcanic activity began between one half and one million years ago, with the most recent eruption cycle ending about 1,000 years ago.

Is Mt Rainier male or female?


Re: Mountains: Male or Female? Mount Rainier is definitely a lady! Especially with her long flowing hair.

How many bodies are on Mt Rainier?

The National Park Service has compiled a long list of death incidents on the mountain since 1897, starting three years after a major eruption. At least 400 (documented) people have died on Mount Rainier since then. The Oregonian picked out some of the ‘most notable’ incidents in a recent article.

How did Mount Rainier form?

Modern Mount Rainier was built by numerous eruptions over the last 500,000 years, alternating between periods of high volume and low volume eruptions. These eruptions built up layer after layer of lava and loose rubble, eventually forming the tall cone that characterizes composite volcanoes.

What type of boundary is Mount Rainier?

convergent interaction

The Cascade Range, in which Mount Rainier is located, is a perfect example of a fundamental concept in geology. It involves a common convergent interaction between tectonic plates where two plates collide and the resulting chain of volcanoes that forms parallel to and inland from the plate boundary.

What are three interesting facts about Mount Rainier?

Mount Rainier became a National Park in 1899 and is the United State’s fifth National Park. The mountain is 14,410 feet tall. Mount Rainier is an active volcano that last erupted about 1,000 years ago. Mount Rainier has 25 major glaciers.

Is Mount Rainier still an active volcano?

Mount Rainier, an active volcano currently at rest between eruptions, is the highest peak in the Cascade Range. Its edifice, capped by snow and 25 glaciers, has been built up by untold eruptions over the past 500,000 years.

What would happen if Mount Rainier erupted?

It would be hot, and it would melt the ice and snow. And tumble over cliffs. “The lava flows encounter those very steep slopes and make avalanches of hot rocks and gas that are hurtling down the mountain maybe 100 miles per hour or so,” Driedger says.

Could Mt Rainier destroy Seattle?

Mt. Rainier would be able to produce the same if not more tephra. The largest threat tephra imposes is the potential to contaminate Seattle’s drinking water, and maybe cave in a few roofs. Mt Rainier has the potential to inflict some serious damage but Seattle may be just far enough from its reach.

Is Mt Rainier bigger than Mt St Helens?

Helens. However, owing to the volcano’s great height and widespread cover of snow and glacier ice, eruption triggered debris flows (lahars) at Mount Rainier are likely to be much larger–and will travel a greater distance–than those at Mount St. Helens in 1980.
