The Rocky Mountains were formed between 80 and 35 million years ago by what is called the Laramide orogeny. Basically the oceanic crust got pushed under the continâ¦ental crust and large landforms were crated. Over millions of years, erosion sculpted the mountains into what we see today.

It seems that since mountain ranges are created through the collision of tectonic plates (theoretically!), the scale of mountain creation is somewhere on the scale of tens to hundreds of millions of years. This of course depends on the specifics of the mountain we are discussing. To take a specific case: the Appalachian mountains on the northeastern seaboard of North America, took about 100 million years to completely form before plates shifted in a different direction.
