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.
Cataclysmic eruptions in the past few million years created huge volcanic depressions called âcalderas.â The youngest, the Yellowstone Caldera, was formed 640,000 years ago. Since then, about 80 eruptions of rhyolite (thick, sticky lava) and basalt (more-fluid lava) have occurred.
