It was a frosty morning and I had gotten up to check the sunrise for pictorial magnificence. Too clear, but as I watched the ground fog moving on the valley floor, I kept thinking, I should get a video of this. Unfortunately for you, it was too fascinating to watch for me to break away and get the camera. It really did look a bit like the ghostly figures of a band of horses rising up out of the fog hundreds of feet in the air and then disappearing—all within a few seconds. The underlying herd was in a stampede down the valley. When it eventually settled down, I did go out and take a couple of pictures of a much calmer scene.
