Because of quick cooling, the basalt in the Flume is a fine- grained rock. After the Ice age, Flume Brook began to flow through the valley again. It mostly filled the valley with glacial debris and also removed soil and even weathered rock from vincity. The Gorge was covered by glaciers during the Ice Age, but the ice sheets did not greatly change the surface. Sometimes after the fractures were formed, small dikes of basalt were forced up along the fractures.The basalt comes from deep within the earth as a fluid material, and because of the pressure was able to force the conway granite aside. As the granite cooled it was broken by closely spaced vertical fractures which lay almost parallel in a north-east direction. The Conway granite that forms the walls of the Flume was deeply buried molten rock. On the walls of the gorge small trees are still growing. As you walk through the Flume look at the floor of the Gorge and you may notice remnants of the main basalt dike. The greatly fractured granite and basalt have been eroded by frost action also by the water coming from the brook. As the overlying rock was worn away, pressure was relieved and horizontal cracks developed, allowing water to get into the rocks layers. The Flume was mainly created by erosion lowering the earth’s surface and exposed the dikes. What impact does the climate for Franconia, New Hampshire impact the people living there? Climate for Franconia, New Hampshire has a big impact on the people living there such as how much they have to pay to have electricity and water and even more. How did weathering impact and form the Flume? Weathering was a major role in forming the flume just like erosion some weathering issues can have a bad impact on the future of the Flume. How did deposition help erosion form the flume? Deposition played a minor role in forming the Flume but it helped in a few ways and was just as helpful to the Flume as erosion was. The Flume Gorge, located in Franconia Notch State Park, New Hampshire is mainly formed by erosion,deposition,and weathering! How much did erosion form the Flume? Erosion formed the Flume in many different ways some ways more than others and the Flume could have easily been destroyed by some of the formations erosion brought.
