People from all over come to experience the Grand Canyon National Park, located exclusively in North Arizona. Covered with unexplored caves and valleys, and immense canyons, the Grand Canyon is very well liked for hikers, whether that hiker is experience of a beginner. This park offers recreational events for everyone. Today, the Grand Canyon stretches out to be eighteen miles long in some places. The Grand Canyon has much to offer from hiking along a rough, yet narrow landscape, bringing the family out to camp for a few days, gazing at the amazing scenery, or visiting the Indian reservations. This area contains several ecosystems and also hundreds to thousands of unique plants and animals. “It contains fossils of corals, crinoids, and brachiopods that indicate warm tropical conditions in a sea that once stretched across the continent. The stone looks different from the red wall, because 500 million years ago the ocean was closer to the ancient continent, and any mud and sand that washed off the land mixed in with the lime, making it crumbly and yellow” (Weintraub 24). The rock layers in the canyon make a magnificent color of stripes in the canyon walls that could be seen miles and miles away. Not only is this canyon enormous, but also this vast canyon can be seen from space. Although the canyon is not the deepest canyon in the world, it is known for its tremendous dimension and its vibrant landscape. This terrain reserves more than two thousand archeological sites of Native Americans, who have also resided there for four thousand years.
The park itself became a National Park in the year 1919. The Grand Canyon is a stunning place to visit for all ages, and for the family to see the remarkable canyon formed not only by the erosi...

... patches along the river” (Halvorsen 5). Separate from the eroding motion of the Colorado River, the flow of the debris played a major, yet foremost role in the broadening and expanding of the Grand Canyon.
All these elements contributed to the creation of the Grand Canyon, which still till this day remains a fascinating story and feature for every one of us, especially geologists, who still have many thoughts as to how the Grand Canyon was even formed. Rock layers that have formed the Grand Canyon, as everyone has seen, are created due to the sedimentations of the seas and the oceans. All of this is precisely evident of the fact that the rocks that are found on the sides of the canyon are made of sedimentary rocks. Scientists have said that the erosion is how the Grand Canyon was form, but there can always be something new to every evaluation of the Grand Canyon.
...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.
The Mystery of Chaco Canyon introduces viewers to a very complex structure that was built by Ancient Pueblo Indians. Although there is no language to explain the structure’s meaning and purpose, researchers were able to read their architecture as a language. Four themes that were extracted from the structure were, the native’s immense understanding of astronomy, the use for the structure, the level of spirituality that the structure represents, and migration from Chaco Canyon.
Petrified Forest National Park is located in the Painted Desert in northeastern Arizona taking up 93,532.57 acres of its land. Before the national park was established, it was founded as a National Monument on December 8, 1906 when President Theodore Roosevelt signed the proclamation. Years later, the Congress passed a bill and established it as a national park on December 9, 1962. Centuries before Petrified Forest National Park was preserved as a national park, the land was preoccupied by the Paleo people. At the onset of the end of the last Ice Age, hunter-gatherers, people who lived by hunting game and only gathering edible plants, roamed the Southwest from 13,500 to 8000 B.C. Although these people enjoy meals consisting of meat and vegetables, they don’t raise livestock and grow crops. During these years of hunting and gathering, the region was cooler with a grassland environment, and people gathered wild plants for food and hunted bison and other large herd of animals. The types of bison these people hunted are now extinct. Nomads used a device called an atlatl to throw their weapons, such as spears and darts, to hunt. By 4000 B.C., during the archaic culture, the climate had changed and became similar to the one of the present. This period of hunting, gathering, and farming had lasted from 8000 to 500 B.C. In contrast to the time of the Paleo people, the climate was warmer, people extended their access to different types of food, and people began to farm and grow their crops. Due to the extinction of animals of the past, people had to expand their source of food, and they had to include many different species of plants and animals into their meals. Two hundred twenty-five million years ago, trees fell and were washe...
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.
Since its creation in 1916, the National Park Service (NPS) has had to balance between its two goals, which are to preserve wilderness and nature and to provide the public with access to these wonders in a monitored environment. These two goals tend to create a conflict for the NPS because as soon as one goal is given more priority than the other, the administration of national parks is harshly criticized by the public. The accusation that by allowing people to experience the wilderness, the NPS is corrupting the natural environment is very common, as well, as the criticism towards the lack of government funding to preserve nature and history. However, regardless of arguable criticism and a certain need for improvement, after one hundred years,
“Don’t waste that water! Kids in Africa don’t even have water to drink!” Almost every American has heard this saying before. We have heard this because there are water shortages in third world countries like Africa, as seen in the movie “Blue Gold”. But why have we developed this notion that there are only water shortages in third world countries? When in reality, there is a shortage of water right here in our home country. The Colorado River’s water is high in demand as it serves millions of people, powers industries, and is home to all different kinds of wildlife. The Colorado River will not be able to keep up with the increasing demand of water and soon enough the river will go dry. Organizations like the Colorado River Water Users Association are trying to change the way that the water is used and adjust how it is managed. The Colorado River is drying up and the western states are running out of water, however, public policy is trying to regulate and preserve the Colorado River to make it more sustainable in the future.
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
Ice dams in the Clark Fork area that backed up Glacial Lake Missoula actually caused some of the largest floods known to man. As ice will float, these ice dams would periodically rise up and burst, catastrophically flooding the Rathdrum Prairie, eastern Washington and into northern Oregon. Locally, these floods brought in glacial till and deep deposits of outwash that obliterated the St. Joe River once running through the Rathdrum Prairie. The southernmost edge of these deposits terminated where Coeur d’Alene exists today, damming the old St. Joe River and creating Lake Coeur d’Alene (Alt and Hyndman, 73). The new lake received the entire flow of the Coeur d’Alene and St. Joe Rivers, more than could be absorbed through the gravel deposits, thereby causing the lake to overflow and seek a new course, now known as the Spokane Ri...
Arizona has first been explored by a European in 1539. In this year, Marcos de Niza, from Spain, explored parts of the area of Arizona. The area which is now known as Arizona was then inhabited by indigenous peoples like the Hopi and the Navajo. Marcos de Niza had met another peoples of the area; the Sobaipuri. There was a legend about the wealthy seven cities of Cibola; seven cities that would be in possession of valuable treasures. Marcos de Niza was informed about Cibola by an Indian informer. When de Niza returned from his exhibition, he claimed he had seen de Seven Cities of Cibola in the distance.
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...

During my trip to the Arboretum I thought a lot about the importance of the desert. I thought about how complex and beautiful it is. It is a landscape that I do not think many people view as beautiful. I know that when I first came to visit Phoenix I thought the desert was quite ugly. It wasn’t until I made an effort to find its exquisiteness that I did. Participating in activities like visiting the arboretum and taking day trips to Sedona and Tuscon have helped me to see the magnificence of a cactus existing in the sand with no water for weeks at a time. This one thing amazes me so much. The blooming flowers on a cactus are breathtaking to me. I think the contrast of cactus flowers and the vastness of the sand in the desert is what makes it so striking.
