Santa Monica Mountains Essay

To begin, the mouth of the canyon features a hilly landscape with scars from landslides created from the uplifting of land by the Wasatch Fault. The fault, responsible for the creation of the Wasatch Mountains 25 million years ago, is a normal fault (Eldredge, 2014). Unlike some faults, vertical movement of the terrain is limited and slippage only occurs every several hundred or thousand years. Signs of the fault at work can be seen through the mouth of the canyon with the orange Tintic Quartzite which is dated back to the Cambrian Age. Layered beneath the quartzite is tillite from the Precambrian Age. To the west and separate from the Quartzite and tillite by the Wasatch Vault are limestone sections from the Missippian Age. (Rigby, Hintze, 1968, pg 23).

“Something is happening in our world. The masses of people are rising up. And wherever they are assembled today, whether they are in Johannesburg, South Africa; Nairobi, Kenya; Accra, Ghana; New York City; Atlanta, Georgia; Jackson, Mississippi; or Memphis, Tennessee -- the cry is always the same: "We want to be free."(MLK, “I’ve Been to the Mountaintop”).” “I’ve been to the Mountaintop,” by Martin Luther King Jr., is one of the greatest speeches ever delivered. Delivered on April 3, 1968 at Memphis, Tennessee, Martin Luther King Jr. gave this speech to inform the audience about the events that occurred during the ongoing Memphis Sanitation Strike and inform the audience about the problems with the human rights of all people, especially African

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.

The formation of San Diego region involved numerous activities which varied from volcano activities, the formation of Gulf, uplifting and tilting among others. These activities happened in a long span of time creating three distinct geomorphic regions: the west of peninsular rangers, peninsular ranges region, and the Salton Trough region. The geomorphic division reflects the basic difference amid geographic parts containing Mesozoic metavolcanic, metasedimentary, and plutonic rock material. The development of these features resulted to the occurrence of the current San Diego state. The integration of different rocks, volcanic activities, and subduction processes resulted to the development of peninsular region and Salton Trough.

The first Region is the Blue Ridge Mountains this region is located in the North Eastern part of Georgia. This region is home to The Blue Ridge Mountains, which is the southernmost point in The Appalachian Mountain Chain. It is home to Georgia’s highest point, Brasstown bald at 4,784 feet above Sea Level. The First American Gold Rush took place here in 1828.

I decided for my project that I would spend the time researching Mount Baker. Mount Baker is located about 30 miles east of Bellingham, Washington. The Cascade Mountain range extends over 140 miles between Seattle, Washington and Vancouver, Canada. Mount Baker is a Stratovolcano, which is also known as a composite volcano, it is also the highest peak in the North Cascades and the fifth highest in the Cascade mountain range (Volcano Hazards Programs). Cities located near Mount Baker include Abbotsford, British Columbia and Bellingham, Washington. The closest stream to the mountain is the Nooksack River which runs near the west side of the mountain. On the southwest side of the mountain is Baker Lake. I chose this area because it is a very

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.

Another important thing to mention in this picture is the vegetation that is growing on top of the cliff since it is so close to the coastal line. This picture is only a glimpse into what surrounds these cliffs since there are many different landmarks and lithosphere actions considering it is close to the san andreas fault, the monteray bay fault and the palo calorado

The Coso Mountain Range is located at the intersection of the Great Basin and California culture area just above the eastern California desert. This region was left with arroyo walls, lava flows and pyroclastic boulders covered with petroglyphs of zoomorphic and anthropomorphic images (127). Petroglyphs are images created by carving, pecking or incising images into rock surfaces. The most common rock art element found in the Coso Range is that of bighorn sheep (129). Although bighorn sheep images were common in other parts of the Great Basin and the Southwest, these elements were seen in far greater quantities in the Coso Range. The bighorn sheep image represents more than half of the 100,000 rock art elements discovered in this region. Many

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.

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,

The San Francisco Peaks are located in Northern Arizona, seven miles outside of Flagstaff. The weather on these peaks is not very consistent. Some winters there’s excess of snow for skiing, then there are years like the 2001- 2002 ski season where there were only four inches of snow the whole winter. This

For the Puritans in the early New England colonies life was by no means easy, but there was the possibility to expand their beliefs free from the persecution from Church of England. They had the opportunity to create their ideal society under God with the bible as their law from which they would define how to live. The Puritans set out to create their model society which could spread and cull the impurities from the church. But how did these beliefs and goals ultimately effect their society?
