A necklace of colored lights against light blue sky, about 800 yards long, moving slowly north. Blue sky could be seen through the center of the necklace. Lights disappeared simultaneously.We were returning from a hunting trip, binoculars on the seat, two different vehicles, four people. When I saw the necklace (I call it the Nevada Necklace), it was about 16 miles across the valley above the mountains between Hoppi Basin and Gamble Canyon, in clear view. I said, "What is that?" and picked up my binoculars immediately and looked at the object carefully. It was moving slowly to the north. After viewing the necklace for several seconds, the multi-colored lights of the object simply turned off or disappeared with no after image. The object was too high above the mountain to have been able to descend to the mountain or behind it. I asked my passenger if she had seen it. She said "Yes." The other vehicle containing her husband and son was about three minutes behind us on the same road. We waited for them. When they arrived, they confirmed seeing the same object. In about five minutes we were back in Montello and there were several fighter jets flying all over the valley at that time as it got dark. I wrote up an incident report and sent it to MUFON but never heard back from them at all.
