Are the pacific coast mountains worn down?

The Pacific Coast Mountains are a mountain range running along the Pacific coast of North America. They were formed by the collision of the North American Plate and the Juan de Fuca Plate millions of years ago. The Pacific Coast Mountains are still being uplifted today, but they are also being eroded by glaciers, rivers, and ocean waves. The combination of uplift and erosion has created a landscape that is both rugged and beautiful.
