The Glaciers of Yosemite National Park Essay -- Geology

The Glaciers of Yosemite guinea pig Park One of natures most powerful and influential forces is also virtuoso of natures coldest and slowest processes. These great icy rivers argon called glaciers and seduce formed some of the most beautiful scenery on this planet. These enormous frozen bodies of water atomic number 18 often thousands of feet wide and deep and many miles farsighted. They cover millions of acres of land and drastically change the land into beautiful mountains with many amazing features. One of the areas where glaciers have been most influential is in Yosemite National Park in California. Here almost every glacial feature is shown. However, before this information about glaciers in Yosemite was clear, there was the Yosemite Controversy with arguments of different views of how the valley originated. Glaciers are best described in this passage by naturalist John Muir (Bailey) (Guyton)The work of glaciers, especially the embark on they have played in sculpturing the face of the earth, is as yet but little understood, because they have so few loving observers willing to remain with them long enough to appreciate them. Water rivers work openly where people dwell, and so does the rain and the dew, and the great salt sea embracing all the world and still the universal ocean of air, though invisible, yet it speaks aloud in a thousand voices, and explains its modes of working and its power. But glaciers, back in their cold solitudes, work by from men, exerting their tremendous energies in silence and darkness. Outspread, spirit-like, they brood above the long predestined landscapes, working on unwearied though unmeasured ages, until, in the fullness of time, the mountains and valleys and plains are brought forth, channels furrowed for the rive... ... which shaped the valley even more. Rock scratch has shaped the Royal Arches and Mirror Lake. Recently in July of 1996, there was a large rock fall and in January of 1997 the Merced River flooded provi ng that the geology of Yosemite is a forever changing process that still goes on to this day.
