The Rocky Mountains stretch more than 3000 miles 4800 kilometers from British Columbia in Canada to New Mexico in the United States forming the Continental Divide sometimes known as the backbone of North America. Generally the ranges included in the Rockies stretch from northern Alberta and British Columbia southward to New Mexico a distance of some 3000 miles 4800 km.

The Rocky Mountains formed 80 million to 55 million years ago during the Laramide orogeny in which a number of plates began sliding underneath the North American plate.

History of the rocky mountains. Human History of the Rocky Mountains The Rocky Mountains have been home to various Paleo-Indian tribes and more modern Native American tribes for thousands of years. TIME AND FORM OF THE MOUNTAIN FOLDING The growth of the Rocky Mountains began about 60000000 years ago at the close of the Mesozoic era or the Age of Reptiles. Since then further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks and valleys.

The natural history of the Rocky Mountains began over 170 million years ago and has followed a repeating cycle of land upheaval followed by thousands of years of erosion. The Laramide orogeny period also known as the mountain-building period saw the Farallon ocean plate move underneath the North American tectonic plate at a low angle. The mountains themselves were caused by tectonic forces and the rocks that they are comprised of were formed a very long time ago.

For example there is evidence that Paleo-Indians may have hunted in the region as far back as 5400 to 5800 years ago based on rock walls they constructed to trap game like the now-extinct mammoth. The Canadian segment of the Rockies extends 1200 km from the American borders of BC and Alberta to the Liard River Basin flanked on the west by a distinct trench and on the east by rolling foothills. Settlers began arriving in the mid-1800s displacing the Native Americans who mostly left the area voluntarily by 1860 while others were removed to reservations by 1.

The Cache la Poudre River which emerges from the tundra of Rocky Mountain National Park and mountainous areas to the north of the park and flows eastward out onto the eastern Colorado plains to join the South Plate River. Rocky Mountains byname the Rockies mountain range forming the cordilleran backbone of the great upland system that dominates the western North American continent. In fact the oldest rocks that are found in the chain are more than one billion years old.

Rocky Mountains North Americas largest mountain system are widely known for their vistas of spacious subalpine valleys and rugged exposed rock faces. The Rocky Mountain Horse developed in the USA for multi-purpose riding driving and light draft works. The Rocky Mountains formed during the Laramide orogeny period between 80 million to 55 million years ago.

The western United States and the Rocky Mountains took shape during three major mountain building episodes between 170-40 million years ago MYA. The angle of subduction was shallow resulting in a broad belt of mountains running down western North America. Along with their gentle disposition they are famous for their four-beat ambling gait that is intermediate between a walk and a canter gallop technically called a single-foot gait.

Before the late 18th century when French trappers and Spaniards stepped in the Rocky Mountain area was a land of many tribes including the Nez Perce the Shoshone the Crow the Lakota and the Utes. Also worth considering when it comes to the history of the Rocky Mountains is the human history. The stories of Rocky Mountain National Park began with the earliest inhabitants and will continue for generations.

The National Park Service was created to protect both natural and cultural resources side by side. These mountains eventually eroded leaving behind layers of sedimentary rock. In 1996 Rocky Mountaineer set the record for the longest passenger train in Canadian history.

In 1820 the Long Expedition led by Stephen H. Long for whom Longs Peak was named approached the Rockies via the Platte River. History of Rocky Mountain National Park began when Paleo-Indians traveled along what is now Trail Ridge Road to hunt and forage for food.

The range is made up of over 1000 smaller ranges. This unusual subduction resulted in the forming of mountains but further inland than what would be expected of this kind of tectonic activity. Generally the ranges stretch from British Columbia and northern Alberta all the way to New Mexico in the south.

However it is not unreasonable to say that this glacial epoch has not yet seen its end seeing as how there still remain high in the Rockies some small glacial remnants. The Ancestral Rocky Mountains which existed in the late Paleozoic between 320 million to 280 million years ago were formed during the time when Africa and North America were coming together. This book by Colorado State University entolomogists Howard and Mary Alice Evans provides as the subtitle states a natural history of a Rocky Mountain river.

In places the system is 300 or more miles wide. Ute and Arapaho people subsequently hunted and camped in the area. The widespread glaciation of the Rocky Mountain region is one of the most recent geological activities to occur starting with the Great Ice Age that predates human history.

Exploring the parks human past can tell us things about our role as park stewards now and in the future. Western Canadas Rocky Mountaineer only began in 1990 quickly becoming a much-celebrated travel experience with people flocking from near and far to experience the journey themselves. The Rocky Mountains often called the Rockies are a broad mountain range in western North America.

Canadian Rockies segment of the Rocky Mountains extending southeastward for about 1000 miles 1600 km from northern British Columbia Canada and forming nearly half the 900-mile 1500-km border between the provinces of British Columbia and Alberta. The Rocky Mountains or the Rockies are a picturesque mountain range found in western North America.
