Line of 10-12 lights moving in unusual linear, then angled pattern

Star-light bright small shapes traveling at about small; airplane speed north aligned in a more or less east-west string moving just above the mountain tops (and behind the trees in my back yard)to the west of Laramie.  The objects proceeded northward at a slight angle (so you could see multiples in a line) spanning the width of my hand at arms length. The line of objects appeared to turn slightly to the west with the pivot point at the far end.Once the objects lined up on the eastern end object, they faded completely away.  I saw a similar light show in the back country of Colorado about 15 years ago in the South Platte Valley, except it was a v-shaped alignment of similar star-bright objects.
