Naturally Opaque

I left California and the fog was so bad you could barely see a few feet in front of you. It delayed flights as the planes in the air couldn't land and those on the ground couldn't take off.

I wasn't bothered because it was beautiful. I love the look and reminds me of fantasy world's I have read and imagined in my mind. What is just on the other side of the fog? Something beautiful? Something terrifying? Something you could never imagine?
