When in those high 12,000 ft basins in the High Uinta Wilderness, the planes flying over make a big racket. Even the little planes are very noisy. One night, or morning, a 2:00 am nature call had me standing out in the night when I saw a very bright light on the ridge. My first thought was somebody had snuck a 4 wheeler into the wilderness but then I realized it was flying. My next thought was a high plane still had his landing lights on but as it passed overhead, the light remained bright, so it was not a directional light such as a headlight or landing light. I could not make out any shape of a craft or anything. As the light moved further away it remained very bright and then, when about over the Vernal Basin where the towns are, it suddenly went out. About that time I realized that whatever it was had made no noise whatsoever. Definately a UFO (it may be identified by someone else but not me) but one of ours or theirs? Who knows?
