The Laramide Rockies formed between about 85-50 million years ago. A popular theory is this event was caused by "flat slab subduction" of over-thickened oceanic crust. From your understanding of mountain building processes in this part of the course, evaluate the following question(s).


If these mountains formed 50 million years ago, why are they still high?

Although the mountains ceased actively deforming isostasy continues to produce uplift as erosion sculpts the landscape (there is clearly more to this, such as the role of Cenozoic thermal events, but that is beyond the scope of this class level).
