This is a photo shot in denali in sequence, the before and after photos of same shot taken within seconds of each other don't have this anomaly. this isn't my photo. a friend took this on vacation, visiting the park during a cruise excursion. he was showing me his vacation photos when i noticed the smudge like spot in the upper right hand corner. i zoomed in and we felt that the level of detail was alarming. he did not see this object while he was there taking the photograph
