So you now know how sedimentary rocks are formed and how the Colorado River majorly eroded all the rock creating canyons. But here comes the million dollar question: where did all the rocks come from? The answer to that question is The Continental Drift. The Earth's continents are not fixed in place, but rather float on a sea of molten rock, meaning that they move around quite a bit. Over 250 million years, that “quite a bit” can turn into land masses moving thousands of miles. Moreover, the Earth is made up of 20 Tectonic plates. Seven of these plates are very large and consist of entire continents or sea floors. The plate that the Grand Canyon is located on is called “The North American Plate”. At one time, this plate was considerably further south and consequently had a very different climate than

The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as

We usually think of the Grand Canyon in terms of its rocks, and the story and history that they can contain, spanning as far back as half of the Earth’s age. There is more to this canyon though than the rocks, as it is still active as a forever changing landform, due to the power of running water. The Colorado River has carved out the Grand Canyon in just the last nine million years. In fact, the river itself carries about half a million tons of sediment through the Grand Canyon each and every day. There are a number of different river types that will be talked about, and how exactly they have effected their environment and made changes in the landscapes.

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

Mesa Verde National Park on the Colorado Plateau contains many geological aspects of interest, including its sedimentary rock layers, its canyons, its alcoves utilized by ancient people and how these alcoves were formed. Mesa Verde National Park is located in the southwest corner of Colorado, close to the Four Corners area, on top of a high mesa overlooking the Mancos River (Harris et al. 2004). The park, covering 81 square miles, consists of several main sedimentary formations that are characteristic to the park (Encyclopedia Britannica 2015). Canyons are carved into the sedimentary rock, with the cave dwellings found high on their steep walls. These dwellings are an especially unique aspect to the Mesa Verde National Park, and are built out of large alcoves. The alcoves were produced by weathering and erosion of the sedimentary rock type. To better understand how these alcoves formed, we must understand the geology of Mesa Verde National Park and how it has developed over history.

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.

Around 650 A.D., the Mesa Verdean peoples initiated construction of apartment-style homes, termed by Spanish explorers as pueblos. The Puebloan architecture is original in that it utilized the local stone and mud deposits of the region to maintain the structural integrity of their burgeoning developments. As this community evolved into the twelfth century, Mesa Verdeans further integrated the geology of their environment into their lifestyles by building homes, known as cliff dwellings, within the naturally formed alcoves of Mesa Verde. By the thirteenth century, the Mesa Verdeans vacated this region due to severe droughts and subsequent social instability. Despite the later abandonment of their cliff dwellings, it is clear that the geology of Mesa Verde National Park impacted the lives of the Ancestral Puebloans significantly. The following sections provide detailed information regarding the rock formations that make up the geological

Away from the glitz and glamour of the Strip, there is a hidden nature preservation called Red Rock Canyon. Red Rock is a large national park that contains many things to see, do and experience for people of all ages. You can also bring your dog on some hikes! Red Rock Canyon contains different shades of red and white large rock formations maxing at 1,000 feet tall. There is a long scenic route that circles around the inside of the park to carry you to different formations and trails. Of course, simply trying to describe this geological phenomenon with words does not do it justice. My earliest visit to Red Rock at 10 years old and my latest visit just this past weekend can always be explained with one word, exhilarating.

Thank you for your desire to help us make a difference in Des Moines. We are so very appreciative that people like you are willing to donate time, energy, and experience in a variety of areas, especially for this event.

After over a decade of being re-elected, I would like to keep the winning streak going. We will to utilize and take advantage of some of the tools that has worked in the past for you in order to have a successful election. I want to target those groups that endorse your campaign already, who will most likely be loyal and be an automatic vote. Since Houstonians know what to expect from you, with evidence of a tremendous track record, it will not be as hard to persuade voters. One of the main key issues I want you to target on is to keep our 2nd Amendment Right from being violated or abolished. One of our presidential candidate, Hillary Clinton, if elected would like to make gun laws more sticker. Her idea on this also includes putting a ban on rifles. Texas is a state who loves their guns so by prevent this law it will go over well with the voters, and the National Rifle Association. Another major issue to be discussed is securing our borders. Illegal Immigration is becoming an issue nationwide but especially in Texas with us being so close to the border. Suggesting that we support and assist law enforcement by allowing them to strictly enforce the already existing laws on illegal immigrants. One more concern of Houstonians would be transportation issues. As a native Houstonians you can’t overlook the extreme congestion on highways and streets. Remind the voters of your Katy Freeway project which improved the traffic drastically in the District 7 area.

In regards to the geologic components of Yosemite National Park, it essentially has two main parts. The first part is the deposition and deformation of the metamorphic rocks and the emplacement of the granitic rocks during the Paleozoic and Mesozoic periods. The second part is the uplift, erosion, and glaciation that took place with the rocks during the Cenozoic period. Yosemite National Park is relatively helpful in regards to observing the display of its geologic changes. When the Cretaceous period was ending which was roughly 65 million years ago, the granitic core of the range started to become

Weathering, geologic processes such as erosion, and climatic shifts allow for this immense desert ecosystem to continually evolve and change which has taken place for millions of years. This geologically wealthy environment is composed of alternating flat-lying layers of soft and hard deposits of mostly sedimentary rocks. Interchanging slopes and cliffs along the landscape helped form these layers of rock which can be seen fully exposed in areas of the mesa. Deposition of this landscape mainly occurred during the Permian, Pennsylvanian, Triassic and Jurassic time periods. The assortment of warm hues of sandstone were produced by varying levels of iron oxide minerals during formation.

The geographic region of Mesa Verde captivates me because of its sheer concentration of archeological sites in an area, and the plethora of cliff dwellings found in this region of Colorado. Mesa Verde, a place ancestral Puebloan people called home for hundreds of years from 500 A.D. to the 13th century, is situated on Colorado’s diverse landscape, which consists of 4,400 archaeological sites and 600 cliff dwellings (Smith, 7). Mesa Verde National Park was officially established in the early 1900’s by Theodore Roosevelt in hopes of protecting history and preserving human culture. Since then it has been a site for thousands of archaeologists to dig in to. Before Mesa Verde was receiving the attention it gets today archeologists Bob Lister,

The Grand Canyon is located in Northern Arizona and is part of the Colorado Plateau that was uplifted during tectonic activity. It is said to be more than 1.7 billion years old and filled with many mysteries still about its formation. This immense canyon was cut by the Colorado River that exposed its horizontal layers of rock history. These layers have mostly a red hue but each group of strata has a distinctive color often giving us a sign of its origin.

The Grand Canyon has plenty of volcanic rocks near the bottom and the top. ICR, Institute for Creative Research, has been involved in a project for years to date these volcanic rocks. this study has come a long way to show that many of the Grand Canyon strata could have formed rapidly, and that the erosion of the Canyon by the Colorado River has not been going on for millions of years.
