When did the southern Rocky Mountains Rise?

Introduction

The Rocky Mountains of southern and northern region are considered as the greatest and widespread incision. The Rocky Mountains in Southern of Colorado and Mexico has the 1140 mountains with highest peak elevating more than 3048m, 200 mountains with elevations of more than 3960 m, and 54 mountains with elevations higher than 4270 m respectively. These mountains have the highest peaks on the crest of Rocky Mountains in Southern and Northern regions. It is the multifaceted chain with differing deformational style and age, which extends to Mexico from Northern British Columbia. The exhumation of basin is cutting the canyon, and dissection of planar, which resulted in creation of high level surfaces to relief as much as 1.5 km within the Rocky Mountains, with major portion of it is since Miocene time (McKenna &Love, 1972; Epis and Chapin, 1975). The resemblance in magnitude and timings of incisions depths throughput the Rocky Mountains is related to cause that has been a long time uplift of Cenozoic. However, this understanding has been questioned in the light of suggestions that generation of the relief by tectonic driving forces and climatic may be difficult to differentiate. The resulting elevation in Rocky Mountains means that it has not increased much, but the net tectonic uplift since ca. 35 Ma was not necessary (Gregory and Chase, 1992, 1994). So, in this paper will discuss about the causes and comparisons to assess the roles of climatic changes and tectonics in the cause of post depositional change in the elevation of Rocky Mountains.

Elevation and Topography of Rocky Mountains

The Rocky Mountains in southern region of Mexico and Colorado has the 1140 mountains with highest peak elevating more than 3048m, 200 mountains with elevations of more than 3960 m, and 54 mountains with elevations higher than 4270 m respectively. These mountains have the highest peaks in the mountains of Rocky in Southern and Northern regions. It is the multifaceted chain with differing deformational style and age, which extends to New Mexico starting from Northern British Columbia. In the center of Rockies and the Southern region of the Northern Rocky Mountains, there are not more than 24 Rocky Mountains peaks that do not exceed for more than 3660 m, but few peaks of Rocky Mountains exceed over 3960m (Eaton, 1987). The most part of these Rocky Mountains are not the end, but they are also associated with the thermo tectonic elevation. The north region of the hotspot of Yellow Stone is spread all the way to mostly northern side of the British Columbia, where are no other peaks of mountains that attain the elevations of 3960m. The other two regions of North American plate have no peaks higher than 4270 m. Particularly in California in White Mountains and Sierra Nevada consist of 12 peaks of mountains which are higher than 4270m. This elevation of highest peaks of Whitney Mountains exceed by only 72 m with highest peaks of Southern Rocky Mountains. ...
