multi-colored circle of lights moving slowly in northerly direction above mountains.

This one necklace shaped object moved from left to right, or to the north.  Distance:  about 15 miles.  Length:  800-1500 yards.  The same blue light could be seen around the object and through the circle of lights, the blue light of the sunset.  All lights in the circle moved in unison and the circle of lights was not rotating.  I looked at the object through my 10x50 hunting binoculars.  The event occured at the end of an afternoon of elk hunting.  The object was visible clearly for about 40-60 seconds.  The object disappeared as if the lights were shut off, with no resulting afterimage, only the blue light of the sunset remaining.  There was no sound, no exhaust, no blinking lights.  Within five minutes after the sighting, six to seven military jets shot across the valley in the direction of the object sighted a few minutes before.
