![]() ![]() Once you get to the Gorge, be prepared for stairs…lots of them. However, there is plenty of fun stuff to see on the way there, including this huge glacial boulder. Once you get through the Visitor’s Center (you do have to pay a fee to walk through the Gorge), you have a little walk to get to the actual Gorge. It’s super easy to get to (it’s right off 93) and there is lots of parking and a visitor center. A really fun park is Flume Gorge up in Franconia Notch. These remains of ancient animals and plants provide clues about early humans.It’s almost that time of year when NH State Parks start opening! We are eagerly waiting for this cold weather and snow (yes, we got snow last night) to be replaced with some warmer spring weather, and have already started planning which parks to visit first. The Olduvai Gorge is famous for the fossils and ancient tools found there by scientists Louis, Mary, and Richard Leakey. Olduvai Gorge in Tanzania has layers dating as far back as 2 million years. Many geological discoveries have been made at gorges because gorges often expose layers of rock that go back thousands of years. However, many people worry about the environmental impacts of the dam and criticize the fact that more than a million Chinese families were forced to move from their homes near the gorges in order to complete the construction. The 26 turbines of the Three Gorges Dam generate approximately 18,000 megawatts of electricity for Shanghai and other cities. The new waterway would allow freight ships to navigate from the East China Sea, part of the Pacific Ocean, to the city of Chongqing, about 2,250 kilometers (1,400 miles) inland. Upstream from the dam, the Qutang, Wu, and Xilang gorges were partially submerged in order to create a waterway. The Three Gorges Dam on the Yangtze River in China is probably the most famous example of such a project. These dams generate hydroelectricity, or electricity powered by water. Engineers have purposely flooded gorges in order to create waterways and dams. ![]() states of Washington and Oregon, was partially created by glacial retreat during the last Ice Age. The Columbia River Gorge, located in the U.S. As glaciers melt, or retreat, these gorges and canyons are exposed. These rivers of ice can create huge canyons and sharp, steep gorges. Glaciers cut deep valleys into the Earths surface. The movement and melting of glaciers can also produce gorges. Macocha Gorge in the Jihomoravsk region of the Czech Republic was probably formed by the collapse of an underground cave that had been eroded by the Punkva River. Over time, the power of the waterfall erodes the softer rock layers underneath, causing the original river bed to collapse and create a gorge. As rivers or streams flow across this uplifted surface, waterfalls form. Parts of streams or rivers can be elevated, along with land, during the process of geologic uplift. Erosion and geologic uplift often work together to create gorges. During geologic uplift, rock layers beneath the Earths surface bump against the surface layers. Geologic uplift is often associated with earthquakes and orogeny, the process of creating mountains. Geologic uplift is the upward movement of the Earths surface. The deep Talari Gorges in Mali, for instance, were formed by the Sngal River that flows into the Atlantic Ocean on the western coast of Africa. The flooding of streams or rivers increases the speed and intensity of this erosion, creating deeper and wider gorges. Over time, this erosion will form the steep walls of a gorge. Sediment from the worn-away rock is then carried downstream. Streams carve through hard layers of rock, breaking down or eroding it. ![]() The most common is erosion due to streams or rivers. A gorge is often smaller than a canyon, although both words are used to describe deep, narrow valleys with a stream or river running along their bottom. The term comes from the French word gorge, which means throat or neck. A gorge is a narrow valley with steep, rocky walls located between hills or mountains. ![]()
