Big Bend Rocks

In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.

Next, these rocks undergo erosion, which is the process of moving sediments from one place to another. Then, these sediments are deposited all at one place and over time they start to converge and cement as layers which are also known as strata. As time keeps going, new sediments deposit and cement together over old ones forming new layers. This is a repetitive process that eventually build up layers to make up a Sedimentary rock. Approximately 40 major sedimentary rock layers exposed in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. As you can see, sedimentary rock formation takes an excessive amount of time.

Starved rock and St. Peter Sandstone are an erosional remnant of Ordovician period. These remnants contain Pennsylvanian clastics that survived the washing out of the Illinois River at the end of the Ice Age. Evidence for swift, turbulent, and deep water includes gravel bars and erosional features as high as 160 feet above the current level of the river, massive cross bedded sand, and gravel deposits along the river course.

Conglomerate is a sedimentary rock that consists of rock fragments, many of which are visible to the naked eye (Fig. e The rock cycle states that sedimentary rocks are formed through the compression of sediment, and conglomerate contains minerals and rock that have been compressed, providing visual evidence of the rock cycle (Rocksandminerals.com, 2013).

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

As I looked out the window, I saw walls of rocks all over the place. I also saw a lot of good rock exposure on the top of the mountain where the rock was to steep for the snow to stick to. You will notice that Mount Baker has an abundance of all sorts of rocks. From the rocks I examined I observed a lot of extrusive igneous rock, metamorphic rock and sedimentary rocks and you will find few places where you can walk continuously from shale or basalt into well-metamorphosed gneiss (Tabor & Haugerud). I observed rocks such as gabbro, shale, and types of extrusive and intrusive igneous rock such as basalt. The ages of the rocks range from about as old as the mountain, which is about 140,000 years old.

First, we must examine the sedimentary formations; when they were formed, how they were formed, and what materials they consist of. About ninety-three to one hundred million years ago, the Western Interior Seaway rolled through the North American continent, eventually reaching the geographical area of today’s Mesa Verde National Park (National Park Service 2005). This sea deposited a thick, hard sandstone base that is called Dakota Sandstone, although this layer is not exposed in the park

A description of the grand canyon rock layers would include the Colorado River running at the bottom of the inner gorge with flats on both sides which consist of tapeat sandstone layers. There is also the Vishnu Complex, consisting of rocks that have been changed by heat and are buried at the lowest layers. These are tilted and are called the “Grand Canyon Supergroup” the Grand Canyon supergroups are at least 12,000 ft in thickness. These rocks or (the “Inner Gorge”) are usally steep and narrow with hard deep cuts in the lower tilted layers which raise above sea level.

Today I was given a set of poems to read and choose one to analyze. I decided I would use Big Rock Candy Mountain as my poem of choice. I recognize this poem as a song written by Harry McClintock in 1928. The song is one of the few that can still make sense in today’s culture and society and in my opinion is the mark of a truly great writer.

This formation is a very fine grain Mississippian limestone. To test to see if this was the Bangor formation we used HCL and because there was a reaction we know its limestone. This formation could also be described as gray in color as well as an average thickness of 700 feet. We see the Bangor until stop eight, where we see a very different vertical bedding. Also different at stop eight is the outcrop no longer reacts with HCL. From this we gathered that we had moved into the Hartselle formation. In the Hartselle Formation, Mississippian aged sandstones are dominant. This particular stop had a large amount of jointing. After the Hartselle, we figured the Pride Mountain Formation would be next, however at stop nine we see the Maury Formation present. This stop focused on the rock located inside the creek. Because we were unable to go into the creek to get the strike and dips, we once again had to do a projected orientation. Also found on this stop were natural sulfur springs, easy to notice with the smell that it gives off. The Maury formation consist of Mississippian- Silurian aged shale. At the next stop, stop 10, we encounter the Ft. Payne formation. Although this area location was thickly vegetated, we were able to conduct the acid test and saw that the HCL reacts in some places but not all. From this we concluded that this was the cherty limestone of the Ft. Payne formation. The following stop, 12, we went up section and arrived at the Maury Formation once again. At the final stop, location 13, we see Ft. Payne Formation. All of the metamorphism and deformation in the southernmost Appalachians can be related to the movement of the thrust sheets and stacks (Higgins,

Lava flows of rhyolite and basalt have flowed through parts of Yellowstone as recently as 70,000 years ago. These lava flows destroyed everything in their paths while moving slowly at a rate of a few hundred feet per day, flowing months, or sometimes even several years. They are thick and cover as much as 130 square miles. They have nearly filled the Yellowstone Caldera, and spilled beyond the caldera’s border. These lava flows are responsible for forming four of the nine named plateaus in

Past 360 million years ago, Kentucky was approximately 10 degree to the south of the equator when caves started to form. Kentucky was also occupied with water containing tiny organism having shells of calcium carbonate. When these tiny organisms died, shells accumulation of these creatures together with calcium carbonate emanating from water, built up more than millions of years such that it was hundreds of feet thick. On top of these formations, fifty feet of sandstone were deposited by another river system. Sandstone and limestone were exposed when the sea level started to fall approximately 280 million ago (Thompson & Thompson, 2003). When rivers that we have today started to form, sandstone topped plateau covered the Green River whereas a low limestone plain extended towards southeast direction (Call,

targeted those people who would recognize and appreciate quality lodging and not those who were seeking “cheap sleep”.  Inviting potential guests or individuals who might influence visitor hotel selection to launch parties, swim parties, cocktail parties and other planned events.  Targeting supportive hospitality businesses.  Packages that supported local businesses were developed.

     Rocks are classified to make it easier on people to identify them in the future. This can be done by a numerous amount of ways. Each rock type has their own specific ways, but there are two distinct characteristics that apply to all. These are texture and composition. These two, along with many others helps to classify igneous, sedimentary, and metamorphic rocks.
