I was driving northeast on Mount Rose Highway (431) when I noticed this. Whatever it was had already taken off. After a few minutes it did seem to dissipate. The Tesla Gigafactory is that direction so we thought it could have been a SpaceX test, but nothing was publicized that I could find. It's a bit older of a photo, but a friend just recommended that I send to you guys!
