The Santa Fe Mountains at the southern end of the Rockies as seen from the Sandia Crest in New Mexico The summits of the Teton Range in Wyoming. The name of the mountains is a calque of an Algonquian name, specifically Plains Cree ᐊᓯᓃᐘᒋᐩ asinîwaciy (originally transcribed as-sin-wati), literally "rocky mountain / alp".
In the southern Rocky Mountains, a transition occurs between about 5,900 and 8,200 feet (1,800 and 2,500 m), where plains communities are accompanied by pinyon pines. Two-Needle Pinyon's and singleleaf pinyons are found in western Utah, alligator junipers and Rocky Mountain junipers grow to the south, and Utah junipers grow to the north. Many ...
The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising ...

Called the Laramide orogeny, the compressive forces generated from this collision erased the Cretaceous Seaway, fused the Sierran Arc to the rest of North America and created the Rocky Mountains. This mountain-building event started in the Mesozoic 80 million years ago and lasted well into the first half of the Cenozoic era 30 million years ago ...
Green’s mountain ash (S. scopulina) is native to the mountains from Alaska to California, and east to the Rocky Mountains and Northern Great Plains. It grows as a multi-stemmed shrub that is ...
The west block along the fault line rose to form the Teton Range, creating the youngest mountain range in the Rocky Mountains. The fault's east block fell to form the valley called Jackson Hole. The geological processes that led to the current composition of the oldest rocks in the Teton Range began about 2.5 billion years ago.
Scientists estimate the rebound is causing Everest to grow 0.16 to 0.53 millimeters a year, accounting for as much as half of its annual uplift rate. They said Everest had gained as much as 2 ...
