Odd craft seen in the sky in WyomingA friend and I were returning from Steamboat, CO and our path took us through Wyoming as a shortcut. While traveling through the Snowy Range area, we witnessed an object in the sky that was unlike anything that I have ever seen. It looked like an inverted teardrop or ice cream cone shape. The sky was clear with no clouds on the background. The color of the object was crystalline with definite structure lines that seemed to be silver. It was close enough to tell that it was not a weather balloon or something like that. It was clearly rigid with a defined structure and did not waver back and forth like a balloon would. The object seemed to float steadily and then descended to the ground after several seconds but did not descend all the way to the surface. Rather, it seemed to lower itself below the tree line so that we could not view it anymore.My friend and I were utterly mystified at to what this object was yet we did not feel threatened at any time. I am under the impression that this could be some sort of military application but the shape seemed so inconsistent with anything that humans build.((NUFORC Note: Date is approximate. PD))
