Mt. Saint Helens was a devastating volcano that not only caused many deaths and casualties near itself, but it also changed weather patterns, crop outcomings, and the history of america. Mt saint helens is located in the Cascade mountain range. It is in the county of Skamania, in the north-west corner of the state of washington. Mount St. Helens ripped 57 people from their daily lives and from their families.
Mt. Saint Helens is a Stratovolcano. This means that it has slowly built up over many years by layers of ashes and rock. Stratovolcanoes have a tendency to create pyroclastic flows. These flows are huge waves of dust, ash, and scorching heats. One can usually witness lighting within one. In the case of Mt. Saint Helens, there was no
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
To start, these names are the names of two big volcanos, both in Washington State, both deadly, but on different scales. Mt. Rainier’s last eruption was 150 years ago. Yellowstone’s last eruption was 640,000 years ago. Yellowstone’s reputation of being the ultimate super volcano versus Mt. Rainier, the most dangerous volcano in the country. The difference between these volcanos is looks, damage, stability and tourism.
Mount Saint Helens and Mount Vesuvius are volcanoes that have erupted they are both different and also the same here are some facts, similarities and differences of both the volcanoes.
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
The Teton Wilderness borders the south end of Yellowstone, the western side of Washakie Wilderness, the eastern side of Grand Teton National Park, and the northern region of the Mt Leidy Highlands. This wilderness area spans for 584,708 acres and is located in the state of Wyoming. The Continental Divide runs straight through Teton Wilderness which constructs one of the most interesting hydrological features across the country. This feature is called Two Oceans Pass. The reason why this place is so amazing is because there is a place where water is actually covering the Continental Divide which allows fish to swim from the Pacific Ocean to the Atlantic Ocean drainages. This wilderness area is managed by the Forest Service, and it was declared a wilderness area by Congress in 1964.
Helens is located in Skamania County, Washington at a latitude and longitude 46°11′28″N 122°11′40″W. Mt. St. Helens is a stratovolcano volcano that has an elevation of 2,549m (8363 ft.). The last eruption was 36 years ago and has erupted numerous times within the last 100 years. The eruptions are explosive with ash and pyroclastic flows. Mt. Helens erupted on May 15, 1980 with a VEI 5 rating. It was the only large eruption to happen in the contiguous 48 states since 1915. Fifty-seven people were kill, along with several farm animals. Two hundred miles of land and trees were obliterated. This area is now called the Mount St. Helens National Volcanic
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
What structure is in the Black Hills of South Dakota? What structure has heads of 60 feet high? What structure took 14 years to build? Finally what monstrous granite structure is 5725 feet above sea level? The answer to these questions can be answered in two simple words that have a lot of meaning behind them, Mount Rushmore. Mount Rushmore is a massive monument in the Black Hills of South Dakota. Mount Rushmore has had a tremendous amount of growth as they continue to add new features not to the mountain itself but to areas around it such as gift shops and restaurants. This report shows more information on Mount Rushmore, this report sums up all of the important about Mount Rushmore.
The difference of the 2 pictures is that picture 1 is very green with a skinny lake. In picture 2, everything is grey and the lake is much wider and is flowing much quicker. It also has a huge crater which was made because of a landslide. A science reporter named Eric Sorensen created a timeline on the events that occurred at Mount Saint Helens. It said: On the day of March 15, 1980, a frequent series of earthquakes hit Washington State. They grew stronger and stronger. Finally, a strong 5.1 earthquake hit a mile underneath the volcano. A hole in the icecap appears and a loud boom and a lot of ash occurs. Ice and rock slide into the crater. The booming and heat of the eruption cause a landfall which brought down the entire north face of the
The town of Orting is built in the valley of Mount Rainer in western Washington. Located 30 miles from the volcano, Orting is built upon deposits of 500 year old lahar erupted from the volcano. Mount Rainier is an active stratovolcano of andesitic rock, located along the convergent plate boundary where the North American Plate and the Pacific Plate meet. Mount Rainier is the most prominent mountain in the contiguous United States and is approximately 500,000 years old (The Cardinal). Although Mount Rainier is considered to be an active volcano because of its lahar flow, it is currently in resting state. The last eruption of this massive volcano occurred more than 115 years ago in 1884.

The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
Deep within the Washington wilderness in the shadows of Mount St. Helen lies the infamous Ape Canyon. Upon these steep shallow cliffs, strange encounters have emerged over the past century. In 1924 a group of seasoned miners set out on a routine expedition searching for gold. However, what they encountered changed their lives forever. It was here that allegedly famous attack by a group of sasquatches occurred. In the short autobiography, I Fought the Apemen of Mt. St. Helens by Fred Beck, one of the miners, recollects his parties encounter with the beast.
Mount St. Helens is an active stratovalcano in Skamania County, Washington, in the Pacific Northwest region of the United States. It is located 96 miles south of Seattle and 53 miles northeast of Portland, Oregon. The mountain is part of the Cascade Range. It is most famous for a catastrophic eruption on May 18, 1980. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. 57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoeshaped crater.
