I was in the Big Horn Mountains at Black Mountain range by Taylors mine facing West taking a photo of a sunset. Didn't see this while there taking the photo which i had taken several photos up there, once I got home several days later noticed this green glowing orb in one of my photos, and i can't explain it.I can't say it done anything because i did not see that there while taking photo so it apparently only shows up in the photo i took, did not observe any thing at the time of photo.I feel this is really odd cause something like this should have or would have been noticeable at the time of photo, but i did not see anything... I was elk hunting at the time so i was very aware of my surroundings and was watching the ground frequently looking for elk tracks and trails, not sure how this wasn't observed at the time of photograph, but when i got home and was downloading my photos to computer i noticed this odd globe and then started asking the guys that were elk hunting with me what this could be after we all got home and no one can explain the object in the photo. I also had my German Shepherd Dog with and he didn't appear to have noticed anything like that at the time either.A few days before that me and 2 other gentlemen noticed a flying disc around 30,000 feet in the sky, we looked through binoculars and observed this flying silver disc when taking pictures of this object with iPhone it just appears as a white dot against the clear blue sky, we had also noticed at least 6 US aircraft bombers in that vicinity during the sighting of this silver object, we all concluded that it wasn't a weather ballon but perhaps some sort of saucer drone perhaps. That was the only conclusion we could come up with, other than a flying saucer.the green orb wasn't observed at the time of photograph again i only noticed the green orb after we returned home from a 15 day hunt, we came home on September, 27, 2015 around 21:30the last 3 photos are of the saucer like object 3 of us witnessed a few days before i seen the green globe at taylor's mine
