We were camping at the second lake in the young lakes chain. We witnessed an extremely bright light with four smaller lights behind it, and one larger light trailing behind, rising from in between the ragged peak ridge and a smaller ridge between the 2nd and 3rd lakes. The lights were definitely on a craft of some kind that looked mechanical. We got a VERY upclose view of this craft. It was completely silent and glided through the sky. Unlike anything I'd ever seen before. While I only got about 8 seconds to judge it's size, it seemed to be about the size of a cruise liner. This was not a "strange lights in the sky" sighting. There was no mistaking, this thing was not a plane, or a helicopter, no kind of comet, or drone.
