Transcript of "Badlands national park"

  1. 1. Badlands National Park By; Zach Vulgamott Located in South Dakota, is the grand Badlands National Park. The Badlands has 242,755.94 acres of sharply eroded buttes, pinnacles, and spires with the largest protected mixed grass lands in the entire U.S. The park was made a national monument in 1929. It was not until 1978 that it became a national park. This is a hot spot for any Archeologist's because of fossils there dating back from first dinosaurs to the first mammals. The park has recently been hit by looters, they took some fossils. Also the climate here ranges from -48f to 116f and gets about 12 to 24 inches of snowfall a year. But if the weathers nice, there’s many fun things you can do here like; Activities • Auto Touring • Back Packing • Mountaineering • Biking • Bird Watching • Hiking • Horse-Back Riding • Nature Walks • Star Gazing • Wildlife Viewing
  2. 2. • Cross Country Skiing (Winter) The rocky landscape of Badlands National Park have much history behind them. The rocks are mainly made of sediment that has been deposited over billions of years. These layers are composed of tiny grains of sediments such as sand, silt, and clay that have been cemented together into sedimentary rocks. Those layers have been deposited during the late Cretaceous Period (67-75 million years ago) throughout the late Eocene (34-37 million years ago) and Oligocene Epochs (26-34 million years ago). Different environments-sea, tropical land, and open woodland with meandering rivers, cause different sediments to accumulate here at different times. These layers are similar in character and grouped into units called formations. the oldest formations are at the bottom while the youngest are at the top, Illustrated in the picture below most of this text. The lighter-colored Sharps Formation was deposited from 28 to 30 million years ago by wind and water as the climate continued to dry and cool. Volcanic eruptions to the west continued to supply ash during this time. Today, the Brule and Sharps form the more rugged peaks and canyons of the Badlands. Thick layer of volcanic ash known as the Rockyford Ash was deposited 30 million years ago, forming the bottom layer of the Sharps Formation. The Rockyford Ash is a distinctive marker bed used in geologic mapping. The tannish brown Brule Formation was deposited between 30 and 34 million years ago. As the climate began to dry and cool, the forest gave way to open savannah. Bands of sandstone interspersed among the layers were deposited in channels and mark the course of ancient rivers that flowed from the Black Hills. Red layers found within the Brule Formation are fossil soils called paleosols. The greyish Chadron Formation was deposited between 34 and 37 million years ago by rivers across a flood plain. Each time the rivers flooded, they deposited a new layer on the plain. Alligator fossils indicate that a lush, subtropical forest covered the land. Most fossils found in this formation are from early mammals like the three- toed horse and the large titanothere. The sea drained away with the uplift of the Black Hills and Rocky Mountains, exposing the black ocean mud to air. Upper layers were weathered into a yellow soil, called Yellow Mounds. The mounds are an example of a fossil soil, or paleosol.The black Pierre Shale was deposited between 69 and 75 million years ago when a shallow, inland sea stretched across what is now the Great Plains. Sediment filtered through the seawater, forming a black mud on the sea floor that has since hardened into shale. Fossil clams, ammonites, and sea reptiles confirm the sea environment.
  3. 3. This park is in a relative term to the Rocky Mountain National Park due to the rock formations. The park is also having some road work done so there is a part blocked off for the time being. I think this park is very interesting and I hope others agree too.
