I was hunting elk in september in uintah county between vernal and roosevelt, i noticed a light that didn't move like an airplane. i watched for over an hour with binnoculars and then through a swarovski spotter, dropped and ascended what appeared to be hundreds of feet in seconds. moved from west to east and covered an area i estimate to be 9 miles from the distance i was at. finally went out of site into the north east. i have video, if you want to see it please contact me.
