Mount Baker in Bellingham, Washington Essay

On the first side of the outcrop the rock when examined was greenish and had small black grains indicative of diorite with hornblende giving the green color. The rock was similar to the outcrop encountered at Hollow rock which also had several fractures parallel although not as many, and that outcrop was also highly weathered. On the other side of the outcrop, the rock was incredibly different. This side was not weathered beyond recognition but

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).

I read the book Gathering Blue by Lois Lowry. This book is about being strong through rough times and trusting yourself. In the beginning of the book Kira’s Mom passed away. This was not her first loss, because when she was a tyke her Dad had been killed by beasts.

Our hike will start here, at the north rim of the Grand Canyon. We will go all the way to the bottom of the canyon. But first, a description of this area. The Grand Canyon is one on the most visited and studies sites for geologists on Earth. There are almost forty major sedimentary rock layers exposed in the Grand Canyon. Some of these rocks layers are two hundred million years old or two billion years old. Most of the sediment that makes up the rocks was deposited by oceans and seas, which now, are long gone. We know this because there are many fossils and and other records on large bodies of water in the Grand Canyon. The Grand Canyon is found in the Colorado Plateau. The Colorado Plateau is lifted almost two miles, or four and a fifth kilometers. It started to lift up seventy-five million years ago. This started a mountain-building period of time called the Laramide orogeny. During this period, the Rocky Mountains were created. The main types of rocks found in the Grand Canyon are limestone, siltstone, shale, and sandstone. Many of the layers are made up of limestone. Some examples of these are the Kaibab Limestone, the Redwall Limestone the Temple Butte Limestone, and the Muav

The origin of Mount Washington dates back to over 435 million years ago to a period of time which was called the Taconic Orogeny. During this period of time, there was a massive shift in the earth’s crust which caused North America to crash into a series of volcanic islands. This caused the land to fold and lift to form mountains in the eastern part of the state while also creating a basin in central PA. Over the period of 30 million years these mountains eroded and where moved into the central and western parts of PA. The second period, which was called 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

In far Northern California, about forty miles south of the Oregon-California border, resides the second highest mountain in the Cascade Range and the fifth highest mountain in California. The Cascades are part of the “Ring of Fire,” which is a ring of volcanoes and earthquake sites, around the borders of the Pacific Ocean. Mount Shasta can be seen for several hundred miles and has struck viewers with its remarkable beauty since it was first seen. Mount Shasta towers at 14,162 feet, remains snow-capped throughout the year and is often shrouded in oddly shaped lenticular clouds, or fierce storms that hide it from view. It is awe-inspiring in its geography and geology,

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

Rock Canyon is an excellent site for geologic research and has been investigated by geologists from around Utah and neighboring states. With outstanding extrusions of quartzite, tillite and limestone, it’s a favored destination for hikers, rock climbers and scientists. The quartzite is considered the most unique feature of Rock Canyon as it’s one of the few clear and distinct examples of the sedimentary processes involved with a shallow marine setting. The tillite beneath the quartzite draws attention to the ancient glaciers to the past. In conjunction with the active Wasatch Fault found at its doorstep, Rock Canyon is an important place in Utah for geologists.

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

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.

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
