I don't think its the feeling small, matter of fact, that's a good thing. It's the reason I love going out to the ocean, or standing atop a ski area in Tahoe, or on some 14teener in Colorado. You realize how small you are, how big the world really is.
But its the idea that you have no power over it, or in it. So yeah, the mountain is big, but you can walk and climb up it, and get down too.
