Light brown sphere found in the background of a photograph taken in the Montana mountains while on horseback.I was on a horseback ride with a group of other guests in Montana. We left our guest ranch and were riding in and on the mountains. I was taking photographs of the scenery throughout the ride. When I returned to California from my vacation, I downloaded my photos into my computer. On one photo, I observed this blurred sphere object in the sky. It was light brown in color and appeared to be some distance away. At first I thought something must have been on my camera lens; however, when I reviewed the photos that followed, there was nothing present. Then, I thought it might be a bird, but when I magnified the photo times 800, it was still round. I have no idea what was in that photo.((NUFORC Note: We have looked at the photo provided by the witness, and the object is a small, blurry, brown smudge in the photo. From the information provided, we cannot conclude that it is a genuine UFO. We suspect that it may be a bird or insect in flight. PD))
