One paradox of geology is that weathering a mountain down can actually make it rise higher. Scientists have learned of this peculiar feedback process only in recent years, and the St. Elias Erosion/tectonics Project (STEEP) team is at the forefront of understanding how climate and the movements of Earth’s crust interact to build towering peaks. In this feature video, meet geologists of every stripe collaborating on STEEP in Alaska’s St. Elias Range, one of the most rapidly growing mountain ranges in the world.
