Where is the Horizon Line?

I was looking out the window at the ground. I wondered where the Himalayas were. I had been told that they were majestic, inspirational, unparallelled. So where are they? I look up. I admire the clouds, they are white and fluffy with some interesting contrasting shadows. I begin to try and find shapes in the clouds. Well, that one looks like a face, and that one looks like a mountain...no, wait, what? I pull out my camera. Zoom. Those are mountains.
