When we got home from the Kanaskis trip and I was going though our photos, I noticed a speck in the sky in this picture. I was going to airbrush it out, but when I enlarged it, there appeared to be a UFO. There were no flies around as it was too cool and I am sure I would have noticed if there were a large bird in the area. It was not a blip caused by digitizing the photo as it is on the original slide film. You be the judge.
