I. Introduction-The Grand Canyon
The river has cut through the earth, which allows us to see the passing of eons before our eyes. The Grand Canyon is an impressive one mile deep canyon with red, grey, white, brown, and black rock formations, cliffs, and slopes. The Grand Canyon runs along the Colorado River from Marble Canyon, near the Utah-Arizona border, to Grand Wash Cliffs in Mojave County, Arizona. It is considered to be one of the seven wonders in the natural world. The Grand Canyon became a national park in 1919. It was the seventeenth national park in the United States and one of our planet’s most spectacular landscapes. American Indians have been living in or around the canyon for thousands of years. The rock layers that make up the canyon walls change colors from tan to gold and from brown to black. The Grand Canyon is a remarkable feature in Arizona, but why is it so different from most other canyons and valleys and how did it originate?
The Grand Canyon is one of the largest canyons in the world. It is so vast that various parts of the canyon formed during different time periods. What makes the Grand Canyon so spectacular is its length, width, and depth. Measured along the river, the canyon is 277 river miles or 443 kilometers. The Grand Canyon has a width of 600 feet to 18 miles at its widest point. Lastly, the depth of the Grand Canyon is one mile or 1.6 kilometers. It is carved into a series of elevated plateaus in northern Arizona and has been shaped by erosion and the Colorado River. The canyon is unique both in scenery and the variety of exposed geological features.
II. Formation of The Grand Canyon
Much of the majesty of the Grand Canyon is the result of erosion. Ongoing erosion produces water...

... a “Paradise.” That was the verdict of John Strong Newberry, physician-naturalist. “To look into the Grand Canyon is to look into a rainbow of stone.” Each layer has its own distinct color resulting from the interaction of water and air with the rocks. Below runs the Colorado River as it carves through some of the oldest rocks in North America. As the river carves out the rocks, it can change its own channel, and curve off in new directions. As permanent as the rocks of the Grand Canyon seem, these monuments of stone are constantly eroding. The water and wind are gradually wearing them down and the Colorado River will carry the sediment away. The canyon is one of our planet’s most spectacular landscapes. It is a tapestry of history, geology, and beauty. Geologists are still studying the canyon’s birth and are intrigued by its history and vastness.
Many people know ‘Lake’ Powell as a fact of life. Since its creation in 1963, the reservoir, known as Lake Powell, is just there. Few people that are alive today have had the opportunity to see the true beauty of Glen Canyon, which rivals the Grand Canyon. Glen Canyon, equivalent to one hundred eighty river miles with dozens of side canyons, was flooded for the purpose of power and water resources. ‘Lake’ Powell also generates an enormous cash flow due to the tourism it receives. Although the ‘lake’ has a few reasons to remain in existence, there are many more reasons to drain it.
In the shadow of a cliff wall within Chaco Canyon rests the ruins of Pueblo Bonito, the most famous of the towns and settlements built by the Anasazi over 900 years ago. From tree-ring dating, it is known that a period of severe drought swept through the Chaco area in AD 1150, causing the site to be abandoned. After it was rediscovered in 1849 by U.S. Army soldiers, the site was severely vandalized for seventy years until it was made a national monument in 1907. In 1920, the National Geographic Society began a thorough reconstruction of this once great, and still impressive, site (Chaco Canyon, 1982-2015). Between its construction and its abandonment, Pueblo Bonito was a complex and important locality for the people who poured so much time
Imagine a scenic, wild landscape with animals that roam freely, cascading waterfalls, and mountains that seem to scrape the pale blue sky. This is what one thinks when first hearing the name Yosemite National Park. Unfortunately, the reality is completely opposite. Yosemite is now under a federally regulated Class 1 area under the Clean Air Act, which is equivalent to the pollution of Los Angeles (“National Parks Service”). It is a sad comparison to the past John Muir, who first documented Yosemite Valley, to today’s reality. The condition of Yosemite National Park should be introduced to the American public in order to protect its historic beauty and significance, eliminate current pollution, and prevent future repercussions.
This extended essay will analyze the rhetoric of authors discussing the Glen Canyon Dam. These authors include: Jeff Rubin (The Place No One Knew), John McPhee (Encounters with the Archdruid), Russell Martin (A story that stands like a dam: Glen Canyon and the struggle for the soul of the West), and Jared Farmer (Glen Canyon dammed: inventing Lake Powell and the Canyon country). There are always two sides to an argument, one for one against.
Zig-zag, back and forth, down, down, down, Jonathon, Dad, and I went into a mysterious new world. Now that I have gone into this hot, dry canyon surrounded by monstrous hoodoos, I have seen what it is really like to leave the small town of Seymour, and emerge into the greatness of this world. I have now seen several other National Parks on one of the most renowned places on earth for mysterious creations, the Colorado Plateau. Of all the beautiful places on it, even the Grand Canyon, I have found my favorite one. Bryce Canyon National Park. I thought it was amazing, because it was the most diverse to anything I have ever seen before. We hiked down into it and I felt like I was surrounded by skyscrapers. We trekked around a little, but we didn’t
The world has been shaped by many events. Like a sculpture each piece was a result of an event that made it that way. The Snake River Canyon is no different, most of upper Utah and part southern Idaho show the scars of an event that rocked the landscape into what it is today. When researching and digging in the region you can find remnants of an old marine environment, from sediment deposits to river terraces hundreds of feet high. It’s confusing to think of the area as a giant lake with sandy beaches and powerful waves, but the overflow of this huge lake is what created most of the landscape you can see today. The great Bonneville flood was the world second largest flood, emptying over 32,000 square miles of lake volume. (Utah Geological Society) The flood that the this overfill caused carved through many areas and created the beautiful valley that can be seen there. However, this didn’t just happen over night. The pre-flood history, flood event, specific flood deposits all played an important role in shaping this large Geological marvel. Understanding what happened back then can give us a good glimpse into better understanding the region today, which can lead to better predicting and preserving for the future.
Everyone’s experience is not all the same similarly to the Grand Canyon situation that is mentioned by Percy. The individual needs to be taken into consideration. Like with me, I went to many tourists spots, such as the Valley of Ten Peaks, that are talked among many people that and have been influenced by the media, but when I got their I was left speechless by the sight of the of the Peaks. This experience is a counter point Percy’s idea, that prejudges of situations can skew the perspective of people. Percy states “[a tourist] Does not one see the same sight from the Bright Angel Lodge that Cardenas saw” (Percy 464). This quote explains how people cannot see the true beauty of a sight with these expectations that block it for us. Most of the time I have had my expectations of a sight given to me by media or other people lessen my experiences in life. This occurs because how much someone is willing to let so...
The canyon is a part of what is now the Yellowstone National Park in Wyoming, an area of land first acquired through the Louisiana Purchase. In this painting, the observer may notice many features which stand out. In the background, the image depicts a large, rocky ravine, occupied by a river and rows of trees. The river leads to a large orb of light, presumably stemming from a fire. In the foreground, two men are seen standing on a cliff above the ravine, presumably in awe at the wondrous land they have just discovered in the distance. Behind the men is an untraveled area of
John Wesley Powell was one of the foremost explorers in American history, and his first descent down the Colorado River through the Grand Canyon is one of America’s greatest adventure stories. Although he is not as well known as other explorers, his travels and his contributions to American history are significant because they represent a spirit of discovery motivated not by self-glory or the acquisition of gold or land, but by a curiosity about and appreciation for both the natural world and the native peoples of the West.
The Colorado RIver is best known for being the principal river of the southern United States and Mexico, but it soon could lose that title. Running about 1,500 miles long, the river is a vital source of water for agricultural and urban areas in the southern desert lands of North America. However over the past decade or so, the river has begun to deteriorate. There are many causes and solutions to the deterioration of the Colorado River.
The geology, its history, and the presence of past civilizations contribute to much of the significance of Mesa Verde National Park. The interconnectedness of these aspects should also be noted. If not for the weathering processes and changes in sea level this formation would not exist. Without it, the ancient people would not have been able to reside within Mesa Verde. This National Park now serves as a tool to help conserve the remains of these past civilizations as well as to help educate today’s society on the significance behind this astonishing geologic
As mountain ranges began to reappear, streams and rivers became more vibrant with rushing waters transferring boulders and gravels to different places on the surface of Earth. Water is known to be one of the most significant factors of the Exhumation of the Rockies; however wind is thought to have played an important role in the removal of the mountains from the depths of debris as well. As John David Love has said, “Wind erosion has tremendous significance in this part of the Rocky Mountain region” (McPhee 60). Consistent southwest winds, blowing in the same direction throughout each time period of the Earth’s history, picked up thousands of feet of debris from the surface of the Earth and carried it away into the Atlantic Ocean. The work of erosion through water and wind has given the landscape its

Canyonlands National Park, immense amounts of wilderness and rock, is located at the heart of the Colorado Plateau (Canyonlands National Park-Geology). Millions of years have formed specific features to the rock and surrounding wilderness that make it so special. Throughout the park, you will find that the sedimentary rock has formed many features such as hundreds of colorful canyons, mesas, buttes, fins, arches, and spires. The Green and Colorado rivers have played a major role in the formation of many of these features. These rivers cut through the park forming two massive canyons. This further splits the park into three distinct zones. “Island in the Sky” sits to the north while “The Maze” sits off to the west and “The Needles” to the east (Canyonlands National Park Information Guide). “Island in the Sky” serves as Canyonlands’ observation tower; it allows tourists to see overwhelming vistas of the rest of the land. “The Maze,” as hinted at by the name has been described as a “30 square mile puzzle in sandstone” (NPS: Nature & Science» Geology Resources Division). This section of the park often ranks as one of the most remote and inaccessible areas of the United States. Lastly, “The Needles” is known for its diversity in rock features. Throughout this land, features such as sculptured rock spires, arches, canyons, grabens, and potholes can be seen. The varying names hint at the diversity of the land as a whole. As said by The National Park Service’s Geology Resources Division, “Traces of the Anasazi can be found in almost every canyon in the Needles. Many of their stone and mud dwellings and storehouses are remarkably well-preserved. Tower Ruins, built high on a cliff ledge in a side canyon of Horse Canyon, is an outstanding ex...
The story shows how beautiful and peaceful the scenery is at the beginning, but then man enters and corrupts the perfect scenery. This long and extensive portion of the story that shows the beauty in nature eventually foreshadows the destruction of the canyon when man steps foot into the perfect canyon. The imagery is setting up for the conflict between man and nature. The prospector even digging up the dirt in the search for gold is causing a disturbance in the peacefulness of the canyon. “It [the canyon] was as starlight into atmosphere, shot through and warmed by sunshine, and flower-drenched with sweetness.”
