There was no field of white spread out below this pyramid when I took the picture. It looks like a span of quartz, or a hillside of snow or ice or solar panels. Or snake scales. Or sheets of shiny paper laid out side by side. (What does it look like to you?)
In my un predictable phone camera, I also found a picture without the mysterious white sheeting. As I gazed out the window at the mountain range south of Enterprise, Utah, I was sure I saw a pyramid on the skyline. (Perhaps I've watched too many episodes of "Mummy," but it sure looks like a pyramid to me!)
What else could it be?
