Mount Baker in Bellingham, Washington Essay

To begin, the mouth of the canyon features a hilly landscape with scars from landslides created from the uplifting of land by the Wasatch Fault. The fault, responsible for the creation of the Wasatch Mountains 25 million years ago, is a normal fault (Eldredge, 2014). Unlike some faults, vertical movement of the terrain is limited and slippage only occurs every several hundred or thousand years. Signs of the fault at work can be seen through the mouth of the canyon with the orange Tintic Quartzite which is dated back to the Cambrian Age. Layered beneath the quartzite is tillite from the Precambrian Age. To the west and separate from the Quartzite and tillite by the Wasatch Vault are limestone sections from the Missippian Age.

My eyes peeled open slowly and the bright sunlight flooded into my eyes, blinding me. I heard the sound of running water and felt the cold breeze flow over my body. I looked out of my hammock and in front of me was a beautiful waterfall and several towering, bright green trees. My friends whom were with me shortly awoke and we packed our things and set off on our first true day of hiking in the Appalachian mountains.

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

The Wyandotte caves are made out of limestone like any other cave in Indiana but the Wyandotte cave has a “cliff ”so when people go they have to be careful. There is a Mount Baldy in California but the one in indiana is special. Mount Baldy isn't a mountain, it’s a sand dune. Sand dunes are mountains hills and ridges with sand on them and they “Hide” behind beaches and are affected by tides. In other words Mount Baldy is a mountain with sand on it. Mount Baldy is also known as the “living” sand dune, because every year it is someplace new, South of the shore of Lake

Feel free to stretch, it's been a long ride. We will be stopping by a restaurant later to get some lunch. In front of you, you can see Humphreys Peak, the tallest mountain in the San Francisco Peaks. The San Francisco Peaks is actually a volcanic mountain range and is part of the San Francisco volcanic field. The peaks were once a stratovolcano but is now eroded and are the remains of the volcano. It is the only stratovolcano in the San Francisco Volcanic Field. The tallest mountain, Humphreys Peak, is about twelve thousand, six hundred and thirty-three feet in elevation, which is also three thousand, eight hundred and fifty-one meters tall. In fact, Humphreys Peak is the tallest point in all of Arizona. Also in this area, are more than six hundred volcanoes. Most of the volcanoes found here are basalt cinder cones. These volcanoes are relatively small. They are also usually less than one thousand feet in elevation. Another fact about these basalt cinder cones is that they are formed within a range of a couple of months to a couple of years. The San Francisco Volcanic Field also has several lava domes. Lava domes are formed by dacite and rhyolite magmas. Both of those types of magma are very rich and high in silica. So, as a result, the dacite and rhyolite magmas are very viscous and thick. As a matter of fact, the magmas are so viscous is thick that when volcanoes erupt, the magma tends to pile up and form very steep sided masses, which are the domes.

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

At Laurel Hill Duke Forest there is a large granodiorite cliff adjacent to a river on one side. This cliff is not smooth and has several parallel fractures instead of one steep slope. Observations of this cliff were taken in order to gather data and find possible explanations for why this cliff is where it is located and why the river adjacent to it follows a V-shaped path. One observation was that the range of the strikes and dips of the fractures facing river were all near parallel ranging from strike of 170-190 degrees and dips ranging from 70-90 degrees. There were other fractures oriented differently on other sides of the outcrop. Also, the surface of the outcrop was highly weathered in some parts where the rock type was not distinguishable without using a rock hammer and had moss growing over it.

Mount St. Helen is a very active volcano classified as a stratovolcano, stratovolcano is basically a tall volcano built up of layer after layer of hard lava, tephra, pumice, and volcanic ash. Mount St. Helens location is in Skamania County in Washington, with coordinates of 46 12'00.17"N122 11'21.13"W. Mount St Helen is famous because of its catastrophic eruption on May eighteenth in nineteen eighty. The eruption measured a five on the volcanic explosivity index. This is an index created by Chris Newell and Steven Self in the year nineteen eighty-two it was designed to try and measure the explosiveness of volcano eruptions to determine the value of the explosivity and qualitative observations ranging from zero to eight, eight being the

The blast was preceded by two months of intense activity that included over 10,000 earthquakes, hundreds of small phreatic (steam blasts) , explosions and the north side bulge. A magnitude 5.1 earthquake below the volcano at 8:32 am started the eruption. MSH is still a potentially dangerous and active volcano even though it has been quiet since 1995. In the last 515 years there have been four major eruptions and dozens of lesser eruptions. Two of the eruptions were only two years apart. In 1480, the eruption was about five times larger than the one in May 1980. There have been even larger eruptions during MSH' 50,000 year lifetime. After the May 18, 1980 eruption, there have been five smaller explosive eruptions over a five month period. Since then, there have been 16 dome building eruptions through October 1986 when the new dome in the crater was formed. As the mountain was torn open, the pressure in inside was suddenly relieved. The rock shattered inside the mountain was exploded out the top at speeds over 200 miles per hour. The blast was so strong that it leveled whole forest of fir trees. Geologist call this a "stone wind" since the winds carried the rocks form the blast with them. The rocks gave the winds extra force that let them flatten the trees. 150 square miles of land was leveled. The edges of this area also lost their forested areas from the heat of the blast and the fires it caused. The original blast of the

Mt. St Helens was formed by the subduction of the Juan de fuca plate beneath the continental North American plate. (UNC Edu) Mt.St. Helens didn’t just magically appear throughout the years there were multiple eruptions flows for a long period of time to create it. When hear someone say the cascade mountain range and you wonder what mountains belong you can say Mt. St Helens is one of many mountains of the cascade mountain chain.

On May 18th, 1980 a fiery explosion erupted from a quiet mountain in Washington State, only 100 miles from Seattle. For hundreds of miles thick, dark smoke blew everywhere, and herds of animals, along with huge parts of the forest, left completely demolished. Until many years later, entire ecosystems wiped out entirely. To avoid being completely destroyed, dozens of families evacuated from their property. But geologists learned stuff, so it’s all cool.

Basalt is the most dominant rock found in the area surrounding Mt. St. Helens1. The tephra deposits are found all around Mount Saint Helens and its surrounding areas. Lapilli, course ash, and fine ash specifically make up the tephra deposits that are found in this area1. This western Washington Mountain has been actively erupting for approximately 50,000 years, because it has been erupting for so long means that this mountain possesses very old rock over the past 50,000 years that can be found in the deepest area under its base and hardened lava flow from previous explosions.
