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.
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
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
Rock Canyon is an excellent site for geologic research and has been investigated by geologists from around Utah and neighboring states. With outstanding extrusions of quartzite, tillite and limestone, it’s a favored destination for hikers, rock climbers and scientists. The quartzite is considered the most unique feature of Rock Canyon as it’s one of the few clear and distinct examples of the sedimentary processes involved with a shallow marine setting. The tillite beneath the quartzite draws attention to the ancient glaciers to the past. In conjunction with the active Wasatch Fault found at its doorstep, Rock Canyon is an important place in Utah for geologists.
The Grand Canyon is one of the greatest natural creations our planet has to offer. Have you ever been mesmerized by the giant cliffs, massive ridges, or the wide array of beautiful colors? If you answered yes, this paper is just for you! After reading this, you will be well educated about the Grand Canyon.
Evidence in the Mosaic Canyon; however, do suggest that the area was covered by a warm
Chaco Canyon, located in what is New Mexico today, closer to Arizona, is one of the archeological sites with many hypothesis and conclusions full of contradiction because of its complexity of what was happening there during Chaco’s economical peak. It is one of the prehistorical places that hold the history of the humans and how complex the organization between social, religious and economical was. The remains of the amazing tall and complex buildings surrounded with roads helped the archeologists to hypothesize the use of those buildings and those roads that surrounded them.
I visited a place in Waco Texas where I reside. Waco is situated between Dallas and Austin. It was a park called Indian Spring Park. This park is on the west side of the Brazos River. People
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
Our hike will start here, at the north rim of the Grand Canyon. We will go all the way to the bottom of the canyon. But first, a description of this area. The Grand Canyon is one on the most visited and studies sites for geologists on Earth. There are almost forty major sedimentary rock layers exposed in the Grand Canyon. Some of these rocks layers are two hundred million years old or two billion years old. Most of the sediment that makes up the rocks was deposited by oceans and seas, which now, are long gone. We know this because there are many fossils and and other records on large bodies of water in the Grand Canyon. The Grand Canyon is found in the Colorado Plateau. The Colorado Plateau is lifted almost two miles, or four and a fifth kilometers. It started to lift up seventy-five million years ago. This started a mountain-building period of time called the Laramide orogeny. During this period, the Rocky Mountains were created. The main types of rocks found in the Grand Canyon are limestone, siltstone, shale, and sandstone. Many of the layers are made up of limestone. Some examples of these are the Kaibab Limestone, the Redwall Limestone the Temple Butte Limestone, and the Muav
Near the small town of San Antonio, NM is a spectacular display of one of nature's finest balanced beauty and wilderness paradise, Bosque del Apache National Wildlife Refuge, situated on the northern edge of the Chihuahuan desert and straddling the Rio Grande. Fitting is the name Bosque del Apache, meaning "woods of the Apache," a reminder of the Apache peoples of long ago who lived along the Rio Grande. The 57,331-acre refuge was established in 1939 by President Franklin Delano Roosevelt, an effort aimed to preserve the area as a wildlife habitat. The nucleus of the refuge is 7,000 acres of flood-plain, an extensive area of wetlands and farmlands. Arid foothills and towering mesas ascend to the Chupadera Mountains
Powerful forces of the earth cause a landmass to slide under the water. The hot water from the floor of the ocean then melted the rock from the land, forming granite rocks (U.S. Department of the Interior). Mesozoic volcanic and sedimentary rock are scattered through Sierra Nevada Batholith, which covered most of the park during the Jurassic and Cretaceous times (Harris). Weathering and the batholithic makeup impact the exterior of the landforms within these national parks. Yosemite National Park has a very similar geological history compared to the Sequoia and King Canyon National parks, due to the fact that they all lie in the Sierra Nevada’s peak and western slopes (Harris). When it comes to lithospheric extension in the Death Valley Region, during the time of rapid growth, the plates in this region rapidly expanded. In the region of the Sequoia and King Canyon national park the plates did not expand rapidly, thus indicating that more extension occurred in the Sequoia and Kings Canyon region (Jones). Under the surface, there are many marble caves that are endemic to the area (U.S. Department of the Interior). It is clear that natural forces like these have the ability to create beautiful and interesting geology. The description of the tectonic plates would be an ocean continent subduction zone (U.S. Department of the Interior | U.S. Geological Survey). This occurs because of the above process. A specific rock located in the national park is the Moro Rock. Moro rock is a large granite rock that is shaped like a dome. It was made by the process of exfoliation that has to do with the layers of granite expanding over time (U.S. Department of the Interior | U.S. Geological Survey). The exfoliation process creates many of the rock features located in the park. This exfoliation process is the same one that creates many of
Long before Europeans explored North America, a group of people now known as The Ancestral Puebloans, migrated throughout the four corners region and finally settled in Mesa Verde. For more than 700 years they and their descendants lived and flourished, advancing their build technologies, and material usage. Eventually achieving a clear understanding of their environment, its changing climates, they manipulating their buildings to take advantage of the natural occurrences their communities peeked. Being simple worshippers and having respect for nature their creations left little negative impact on it relative to others of their time. Once reaching their communal peak they suddenly migrated away and disappeared, still today scientist struggle

The objective of the trip to Blount Springs, Alabama was to observe and gather data on the geological structure of the area. Blount Springs is located in the northern part of Alabama just 33 miles north of Birmingham, and lies on the southernmost part of the Appalachian fold belt. The field work began on the morning of Saturday April, 7th at 8:50am. The weather was cloudy with temperatures in the mid 40’s, and the area was wet from rain the previous night. Our materials included a map of the area, list of formations, a Brunton compass, and a Rite in the Rain field book. The procedure of the field work involved 12 stops at outcrops to gather data, one stop was omitted from the original plans. This data gathered included bedding and joint orientations
I chose this site because I thought it would be easier due to the fact that we watch that movie and I already had previous knowledge. Also I thought you would really be amazing to see these structures or at least what remains of
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.
