result of either a long-runout landslide, or a structural pop-up, the Poverty Hills present a unique problem in the geologic community. Located on the western-most edge of the Basin and Range Province in eastern California (Fig.1), and within the Owens Valley basin, flanked by the Sierra Nevada and Inyo/White mountain ranges to the west and east, respectively. The hills are of particular interest as they represent an unusual combination of lithologies, structures, and a geomorphology that is…
sides of the Atlantic. The sequences of sedimentary and igneous rocks from the Appalachian Mountains of North America match those from the Caledonian Mountains of Scotland. Geologists believe that because of the similarities in rock type and rock sequence, both the Appalachian Mountain range and the Caledonian Mountain range were part of the same ancient mountain range known as the Central Pangaean Mountains which were formed when the North American plate and the Eurasian Plate collided. This…
Alfred Wegener is the man that introduced us to the Continental Drift Theory. He spent many years looking for clues from the past to support his idea of drifting continents. Alfred discovered many plants and fossils in many different Continents that where supposedly all together, at one time when they were together it was called Pangaea (Pangaea is the name for what included all current land masses, believed to have been in existence before the continents broke apart during the Jurassic…
Cascade Range and Rocky Mountains enclosing. The interior of the west contains a vast trove of wildlands that are for the most part not managed by the government or any organizations due to the unpopulated nature of the environment. In the meantime, nonnative species of plants have managed to billow into self-sustaining populations within the regions due to lack of oversight within the region. Within the vast interior west, there maintains to be a sole combination of dessert and mountain…
why the Provo River and the Provo City are named that name. Well it is because Etienne Provost gave his name to the Provo River and city. Most people considered Provost the most knowledgeable, skillful, and successful mountain men. In fact they called Provost, “the man of the mountains.” Etienne Provost began to trade fur in the St. Louis trade, where he had lived for 35 years. One day Provost and his men ran into a tribe of Shoshone Indians. The Indians said to Provost, “that they…
Everest or any other mountain worth it?” I knew what my answer was before the period was over. I don’t believe climbing Mount Everest, or any other mountain for that matter, is worth it and this is why. The view or the “feeling” you get at the top is not worth the cold, discomfort, pain, and possible demise that I will most likely suffer in attempts to get to the top. In my personal experience, I have an initial intolerance for cold. This makes the idea of climbing mountains unappealing. Why…
of this provided by Schultz is that of Sailors being deceived by mirages. John Ross on an expedition for the English royal navy, went in search of a northwest passage. Upon arriving at its predicted location however, he found that there was a mountain range where the passage should be. William Parry, Ross’s…
Dear US Geological Survey, I think that you should accept Alfred Wegener’s Theory of Continental Drift. There is a large amount of realistic evidence to prove that this theory did occur. Wegener’s theory is that all seven continents were once joined into a supercontinent called Pangaea. He believes that after continents were in that supercontinent, they gradually moved apart over more than a hundred years ago and will continue to move in the future. This Theory of Continental Drift is supported…
Mount St. Helens is a volcanic stratovolcano still actively located in the Cascade Range in Western North America in the state of Washington. It was formed by a subduction plate boundary also located on the Juan de Fuca plate. The Cascade range is one of the most famous mountain ranges, and has one of the most active volcanos located in Western North America. Other areas or famous landmarks surrounding Mount St. Helens are the South Fork Toutle River, North Fork Toutle River, Castel lake,…
white sandy beaches and pine forests. The highest mountain range in continental Portugal is the Estrela Mountain Range (Serra da Estrela). The Mondego river rises here and then runs down to the City of Coimbra. The river, with many odes composed to it, runs into the Atlantic ocean via the long beach Figueira da Foz. This area is blessed with healing waters that help towns like Luso and Curia to spring up. The natural landscape includes Mountain slopes covered with ancient forests that include…
