Avalanches Avalanches are a common occurrence during the winter and spring months in mountainous regions throughout the world. Through the course of this paper I will discuss two aspects of avalanches that have been studied in significant detail in the recent past. The first aspect of Avalanches that is going to be discussed is the impact of avalanches on geologic formations and biodiversity. Areas that experience avalanches have some specific characteristics that can be attributed to the impact of avalanches, and through these geologic form, information can be gathered about past avalanches. The second aspect is the prediction of avalanches. As people have moved closer to avalanche prone areas and make use of the same for recreation, the importance of forecasting avalanches has become more important. There are a few of different types of avalanches and they are all capable of causing significant damage and change to infrastructure, environment and individuals. The first type of avalanche is referred to as a powder or loose snow avalanche. A powder avalanche generally starts rather small, only a portion of the very recent snow on the surface releases, but as it moves down the slope it accumulates more and more snow. According to the Natural Disasters Association (NDA) website, powder avalanches are caused by a lack of weight in recent snow to create a strong bond between it and older, settled snow. The NDA states that these types of avalanches move at speeds
We learned that Little Cottonwood Canyon is home to geological history, varying rock formations, earthquake potential, ancient glacial formations, landslides, and our effect. This Canyon runs along the Wasatch fault and has much potential for large earthquakes. The mountains have been carved by glacial formations dated back to the Ice Age. Rock falls and landslides have left large boulders as evidence of erosion and moisture in the rocks. The hazards on this mountain range are mass wasting, radon, earthquakes, and the flooding of Little Cottonwood
Another effective technique the author uses is referencing examples of inherent dangers in regard to avalanches. The author references three cases in which avalanches occurred on ski areas to show how avalanches themselves are unpreventable from occurring. This helps benefit the argument since it emphasizes the reality of ski patrollers being helpless when avalanches occur and therefore something that is unavoidable.
This is due to the same factors that caused the 1903 landslide. Geologists are using different technological tools in order to be able to warn those around the mountains of a potential landslide. These tools include seismic monitoring stations and tilt meters. The locations of these sensors are targeted mostly at the South Peak rather than the North Peak which caused the 1903 slide. (Benson, N.D) Canadian Government heavily funds the monitoring of mountains in order to restrict developments in potentially hazardous
Moving on up the trail there is evidence of avalanches and the Limber pines are all wiped out. Some are bent over and still alive, because their roots are attached. Others are a splintered mess from the shock wave produced by an avalanche. This is an unbelievable force that can generate an air blast up to 200 miles per hour. Everything in its path gets wiped out and debris like trees and rock are carried for great distances. Standing in one of these avalanche paths in winter would mean sudden death with no
In the United States alone, landslides are estimated to cause 25 to 50 deaths and over one billion dollars in damage every year (Landslides 101). Landslides may be caused by natural factors or man-made events. Natural factors include over steepened slopes created through erosion caused by rivers, heavy rains or snowmelt saturation slopes and
According to chapter 49 in Geology of National Parks, rocks in these parks mainly consists of some metavolcanic rocks, early Mesozoic metasedimentary along with batholiths made of granite from the Cretaceous period. Also, glacial sediments cover the bedrock in deep valleys and at high elevations. There are also avalanche cutes on the west side of Mount Whitney in the Sequoia National Park which occurs after an avalanche carrying trees, ice, even trees moves down a steep slope leaving behind a smooth path(pg.742). Most of the preexisting rocks in the Sierra Nevada area were destroyed the batholith intrusions, but separate granite intrusion separate curtains or sheets of metamorphic rock called roof pendants which can be found in both the Sequoia and Kings Canyon National Parks. According to the article, “Geology of the Sierra Nevada,” these batholiths are what remains from ancient volcanoes, and the intrusive igneous rocks form underground as the minerals in the molten rock cools down slowly.
In America’s history, Native Americans have been discriminated against and oppressed repeatedly. Various authors have brought attention to the mistreatment of this group of people, and the theme of Natives and the American Dream can be seen in numerous literary works. In the poems “Ellis Island” by Joseph Bruchac III and “Evolution” by Sherman Alexie, the authors bring attention to the hardships Native Americans have faced, and show a different perspective of the American Dream.
Coober Pedy is like a desert town. Coober Pedy has very few residents. Most of the residents live below ground in houses called “Dugouts”. Most of the people live below ground, because of the high daytime temperatures. Coober Pedy wouldn't be affected by a landslide, because a landslide is a sliding down of a mass of earth or rock from a mountain or cliff. It wouldn’t be affected because, Coober Pedy is a desert town, and there aren’t any major mountains around. Coober Pedy, wouldn’t be affected by an avalanche. It wouldn’t be affected because an avalanche is a mass of snow, ice, or rocks falling down a mountain side. Coober Pedy wouldn't be affected by an avalanche because there is no snow, and there are very high temperatures. Coober Pedy
Moreover, the cracking of the ice is portrayed to be an “avalanche” or produce “cracking”
In a thousand spots the traces of the winter avalanche may be perceived, where trees lie broken and strewed on the ground; some entirely destroyed, others bent, leaning upon the rocks of the mountain or transversely upon other trees. The path, as you ascend higher, is intersected by ravines of the
Propaganda has existed for all recorded human history. World War I was the first time that government-organized propaganda was used after the start of war. German military officials attributed propaganda as one of the reasons they lost the war, with even Adolf Hitler saying that propaganda had lowered the morale of Germany. World War II saw an increase in the use of propaganda because countries had adopted Britain’s use of it to sway citizens and soldiers to hold particular views. Once the United States declared war on Japan, the media requested that the government support anti-Japan and anti-German propaganda to convince the American people of the cruel nature of their enemies.
The avalanche was believed initiated from the mountain of Grieskogle, which is 1170-metre higher above the village of Galtür at around 4pm. It penetrated the boundary of the village and came to peace in just a few minutes. The whole event lasted less than 3 minuets, resulting the death of 31 people including tourists and local residents, and destructed half of the village. It was believed that 11 houses were completely buried in the avalanched; 17 further houses were partially destroyed or damaged. The speed of the snow powder in the upper layer reached top
Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several
Although it is certain that violent Earth tremors in themselves are destructive, there are often other kinds of Earth movements that are triggered by earthquake shock waves. Thus, the violent shaking that accompanies many earthquakes often causes rockslides, snow avalanches, and landslides. In some areas these events are frequently more devastating than the Earth tremor itself.
As a kid we all had a dream, one that could have been completely unrealistic, such as becoming an astronaut or following in the steps of our role model. We seek after these jobs because we see successful people on T.V. or people we know that live a happy, lavish life. As adolescence, our minds are fulfilled with the most creative ideas, the highest expectations, and tons of bizarre goals, but the question we need to ask ourselves is how will we accomplish these dreams we place amongst ourselves? Important things we do not think about as kids is what we will major in, or if we are really passionate about the job we believe is the best job for us. Usually we start thinking about what we might want to major in during our junior year of high school when the college searching process begins. Even after we think we know what we are going to major in, we still are not completely confident with our decision. The article I believe will help upcoming Southern Connecticut State University freshmen is Nathan Gebhard’s “Four Steps to Choosing a College Major.” This article would benefit Freshmen by helping them think deeper into what they sincerely want in life. Three key things this article will help incoming freshmen with is choosing their own goals, finding what interests them, and help determine whether a job is right for you.
