It can be difficult determining whether an image of the Viewpoint is level. There are many qualities of the local terrain that make it hard to discern where the horizon really is.
There was a little breeze at the Viewpoint when I stopped by about an hour ago. There were no unusual effects that I could discern. The sky was more or less white. I picked up a few stray cans and had a short conversation with someone I know, as he came passing by. Each time I see the Viewpoint, it's a painting in my mind.
