Why are mountains so awe-inspiring?

Every year I try to make at least one trip to the mountains for a weekend. I made it up there last weekend finally, and found it both completely exhausting physically (I should work out more consistently) and refreshing both mentally and spiritually.

There's something significant about sitting at the foot of a very large mountain and realizing just how small you really are. I think mountains, especially really big ones, mirror the grandeur and scope of God and of his creativity/creation. The magnificence of those enormous mountains is a shadow of what my soul longs for in a magnificent God.
