 In 1909, paleontologist Earl Douglas discovered 150 million dinosaurs fossil beds; The Dinosaur National Monument was establish in 1915 by President Woodrow Wilson in order to preserve the fossil beds.

 August 17, Earl Douglass, Carnegie Museum paleontologist, discovers eight vertebra of an Apatosaurus, the first skeleton discovered and excavated at the Dinosaur Quarry  October 4, President Woodrow Wilson signs presidential proclamation establishing 80 acres surrounding the Dinosaur Quarry as Dinosaur National Monument  July 14, President Franklin D. Roosevelt signs Presidential proclamation expanding monument by approximately 200,000 acres to include the canyons of the Green and Yampa rivers  June 1, Dinosaur Quarry Visitor Center is dedicated and opened to the public  Monument Headquarters Visitor Center and Harpers Corner tour road are dedicated and opened to the public  October 4, The Quarry Exhibit Hall and Quarry Visitor Center are reopened after a 5½ year closure.

Dinosaur National Park U.S.A. Map Dinosaur National Park is located between Utah and Colorado States

Dinosaur national park has many features such as the green river and split mountan

A topographic map of the Utah side, Dinosaur National park has a variety of features such as the canon river.

 Dinosaur NM is a land of ancient fossils, past environments preserved in Stone, where two rivers go across mountains and a landscape with life everywhere

 The Green river extends 730 miles from its source in the Colorado river  The Yampa river extends for nearly 250 miles from its headwaters in Colorado's mountains

Flaming Gorge Dam, 47 miles upstream from the park boundaries. A concrete thin-arch dam on the Green River, a major tributary of the Colorado River, in northern Utah in the United States

 Global warming tied together  Oil and gas development somehow  Air quality problems On March 2015 Feds Set New Rules for Drilling Near Dinosaur National Monument, Oil and gas development can continue in tandem with conservation efforts. Based on previous experience, its known that oil and gas exploration and development adjacent to Dinosaur National Monument could cause air and water pollution, increased noise, loss of wildlife habitat, a decrease in visitors, and numerous environmental impacts from creating new roads to handle the increased traffic.

 Fossils ; All of the rocks exposed in the area are sedimentary mainly because many dinosaurs once roamed at the area and many of them died leaving there fossilized bones in side the rock  all of the exposed rocks in the area are sedimentary rock the age can range from 1100 million years ago to 25 million

 The technology usage at dinosaur national park is helpful because it helps Inform people about harmful occurrences happing at the park so they can help.  The national park websites provide information on the national park and how it is growing and changing.

 The rock layer enclosing the fossils is a sandstone or river bed origin known as the Morrison Formation from the Jurassic Period some 150 Million years old. The dinosaurs and other ancient animals were carried by the river system which eventually entombed their remains.

There are alternative hypothesis on the the stream and river courses through the mountains  Major drainages are superposed streams. Sediments eroded from newly formed Laramide uplifts, filled the adjacent intermountain basins and eventually completely covered the the Laramide structures, resulting in a flat featureless plain.  John Wesley Powell suggested that the streams established their course prior to uplift of the mountains. Powell invented the term antecedent stream to describe this process. ** It is now known that uplift of the mountains occurred prior to the establishment of the stream courses.  Stream piracy, Initially there was a system of streams that flowed away from the Uinta Mountains. The ancestral Upper Green river and the Lower Green combined the drainage system, resulting in rapid down cut of the canyons.

 Existing Clay sediments called bentonite clay has the capacity to accept & expelled water making it shrink and swell. This can cause devastations in the land and man-made structures.  Current fluvial process also can cause erosion and flash flooding’s  Cliff carved into sandstones can collapse, this collapses, erosions and sediments influx creates ever-changing geomorphic landscapes  The tectonic plates can also cause more mountains to be formed and changes in the landscape of the area.
