Crater Lake
Crater Lake is located at southwestern off Highway 62 in Oregon. It is Oregon?s only national park. It is the deepest lake in the United States and is the seventh deepest in the world. Crater Lake has an average diameter of 5.3 miles in length and is approximately 1,932 feet deep.
Crater Lake is a result of a volcanic explosion that happened about 7,000 years ago. A long time ago, the pacific oceanic plate was gradually moving under the pacific continental plate in the process of plate tectonics. The pressure shaped the land to move upward and create a line of mountains that are currently located on the Cascade Range. These lavas piled and cooled on top of each other resulting in mountains like Mazama and Hood. Mount Mazama was built by successive flows of both andesite and dacite lavas. Mount Mazama was a stratovolcano, which was about 12,000 feet high after series of ash, cinders, and pumice explosions built it upward. During it?s final eruption the magma chamber was emptying and the underlying support for the mountain was lost and the walls of the volcano began to collapse. In just a matter of days the top of the mountain was destroyed and left a caldera. A caldera is a word used by geologists to describe large basin-shaped volcanic depressions. The destruction Mount Mazama was what marked the beginning of the formation of Crater Lake. The caldera was about 3,000 feet deep and over time, snow and rai...
...e morphed it into the quartzite that is seen surrounding the butte (4). Rocks that undergo this process are called metamorphic rock, which is the same as the rock seen years ago by dinosaurs and other extinct creatures. The quartzite rocks were formerly seafloor sediment that was forced upwards, and then surrounded by lava basalt flows. Once erupted through fissures and floods through out most of the area, lava flow eventually created enough basalt to form a thickness of about 1.8 kilometers (1). All of this basalt flow eventually led to the covering of most mountains, leaving the buttes uncovered. The igneous lava flows and loess is reasons that the Palouse consists of such sprawling hills, and rich soil for farming (2). In result of the lava flows, the Precambrian rock Quartzite was formed. And lastly covered by the glacial loess, which were carried by the wind.
Have you ever wondered how women helped our country? There was and still are women who changed or change the world today. Like Shirley Muldowney,and Rose Will Monroe, or Elizabeth Cady Stanton, and Susan B. Anthony, maybe Hillary Clinton. Some of these women changed little things and some changed big things, but they all made a difference in their own way.
On May 18th, 1980, one of the most prominent volcanic eruptions in US History took place in the state of Washington. Mount St. Helens had been dormant for almost 100 years before March 15th. On this day, two months before the eruption several small earthquakes shook the earth. This indicated a magma buildup below the surface, and the first minor event that would lead to one of the greatest eruptions the US has ever known. Following the first set of earthquakes, “Steam explosions blasted a 60- to 75-m (200- to 250-ft) wide crater through the volcano 's summit ice cap and covered the snow-clad southeast sector with dark ash. Within a week the crater had grown to about 400 m (1,300 ft) in diameter and two giant crack systems crossed the entire summit area. Eruptions occurred on average from
At the end of the last ice age windblown silt covered the lava and basalt deposits. This silt would go on to create the fertile rolling hills of the Palouse. This soil is more than a hundred feet deep in places. Soon, enough time passed for vegetation to take place and more soil started to form.1 The lava flows would end up damming streams flowing from the mountains; in turn forming the current lakes of the region. Layered between the flows of basalt are sand and gravel deposits that washed down from mountains.1
Mauna Loa is Earth’s largest volcano and most massive mountain as it takes up nearly half of the flourishing landscape of the island of Hawai’i. This island is actually made up of five volcanoes, Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea, all in such close proximity that they fused together to form one whole island. Mauna Loa is located in the south central area of Hawai’i, in the Hawai’i Volcanoes National Park and its coordinates are 19°5' N, 155°6' W. It is 13,680 ft above sea level, but if one measures from its true base on the ocean floor, it is estimated to be 30,080 feet tall. Its name is quite fitting as it means “Tall Mountain”.
In Crow Lake, Mary Lawson portrays a family who experience a great tragedy when Mr. and Mrs. Morrison are killed in a car accident. This tragedy changes the lifestyles of the seven years old protagonist Kate Morrison and her siblings Matt, Luke and Bo. The settings are very important in this novel. Though there are limited numbers of settings, the settings used are highly effective. Without effective use of themes in this novel, the reader would not have been able to connect with the characters and be sympathetic. Lawson uses an exceptionally high degree of literary devices to develop each character in this novel.
In the novel, The Scarlet Letter, both Hester Prynne and Roger Chillingworth are both very strong willed, in more ways than one. Throughout the story, and especially the first few chapters, Hester’s loyalty to her lover shows as her most strongest feature and is as bold as the scarlet letter sitting upon her bosom. Although it sets her back way more than it did her any good (keeping in mind the magistrate said that her lover should stand on the scaffold with her), Hester stood her ground for the one she loves, or did love at one point in time. Going on to Roger Chillingworth, he was not one to give up easily. For one, after many many years of being away at sea, he still managed to make it back to see his wife. However, though, this is pretty much as far as the similarities go. Hester is more of a hot, in the moment kind of person. Roger is detached and cold, strong will and determination probably the only two characteristics making him human.
Mauna Loa is the largest volcano in the world measuring 2,000 miles². Mauna Loa is 13,677 feet tall, 74 miles long, and 64 wide. On March 24, 1984, at 1:30 in the morning, Mauna Loa began to erupt. This eruption is known as a quiet eruption. The eruption does not cause the volcano to explode or make much of a loud noise. This is due to the basaltic lava and a low amount trapped gases. It just flows a low viscosity lava out of the volcano. When the eruption started, lava started pooling out of the top of Mauna Loa. Within 2-3 hours about 80% of the crater on top of the volcano was submerged in lava. Many worried that the lava would overflow and run to the Mauna Loa Observatory, but the eruption shifted to go northeast rift zone instead. This instead threatened the nearby city of Hilo, populating 40,000 people. The lava headed straight for the town. On the way, the lava reached a generator and left it destroyed. This took out the power for the observatory on the other side of the volcano. This lava that Mauna Loa erupted is a basaltic lava. Basaltic lava silica content is low and only contains 45-55% silica. This makes the magma more liquid and gives it the ability to move quickly. As the lava approaches the vulnerable city of Hilo, many of the people began evacuating. Luckily, the lava stopped at the outskirts of town, burying 16 miles of land owned by the state, never to be seen again. The
Greasy Lake is the story of three friends who are bad characters. Until they run into a situation where they question, just how bad they are. Just because they act badly and look bad does not mean they are. They are teenagers in a period, “when courtesy and winning ways [are] out of style when it [is] good to be bad, when they [cultivate] decadence like a taste.” (112) They look bad, wearing torn-up leather jackets, slouching around with toothpicks in their mouths and wearing their shades morning, noon and night. They have the attitude, they drive their parents cars fast, and burn rubber as the pull out of the driveway. They have the bad habits. They drink “gin and grape juice, Tango, Thunderbird, and Bali Hai, [sniff] glue, and ether and what somebody [claims] [is] cocaine.”(112) What starts out as a harmless prank on the third night of their summer vacation turns into a situation where they get into a fight, attempt to rape a girl, find a dead body and see first hand the destruction a bad character can do to an automobile.

Kate Morrison is a well educated, independent woman with a decent job, supportive boyfriend and family. Externally, Kate has a life that some people might envy of but, internally, she isn’t as stable as she seems. Crow Lake, a novel written by Mary Lawson, leads the readers to the protagonist, Kate Morrison and the struggles in her life. Kate loses her parents in her early age and for this reason she lives with her siblings with some help from her neighbours and other family members. Despite the absence of her parents, Kate and her siblings seem to grow well. Although there is some crisis in the family, they seem to be inevitable consequences of not having an adult in the family. However, Kate spends an innumerable amount of time accepting and letting go of the past and eventually it causes another crisis in her present life. She continuously has some kind of depression, and she does not realize that her depression is coming from herself, not from anything or anybody else. Crow Lake contains a great message that shows refusing to face the past affects your future negatively. We see ...
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.

A rift valley is formed on a divergent plate boundary. Divergence of plates happens because of slab pull (plates being pulled apart due to asthenospheric convection). When two plates are pulled apart, a ridge forms, and low-silica magma comes from inside the Earth to make a new crust (this is called plate formation). Rifts can occur at any location, of any elevation and on both types of plates. Rifts usually form vast valleys around the World (a commonly used example is the African Rift Valley, and it is still currently active). There are often large, incredibly deep lakes found in rift valleys (the deepest lake in the world, Lake Baikal is part of an active rift valley). Rift valleys have mostly shallow earthquakes, not devastating at all. Cracks in the valley with lava flowing out of them can also be found (volcanic fissures), along with cinder cone volcanoes. In Garibaldi Provincial Park, in British Columbia there is a cinder cone volcano, with cinder flats surrounding it, similar volcanoes can be found in rift
