We can't tell if this is some kind of "Time's Arrow" situation, but there appears to be a Federation shuttlecraft just blithely parked in a repair lot a block away from Las Vegas' McCarran Airport. Former Verge director Jordan Oplinger discovered the rogue craft over the weekend on Google Maps:

For those who might be unfamiliar, this craft and its brethren would carry the likes of Capt. Jean-Luc Picard and his crew on away missions. This vehicle in particular looks not unlike like a Type 6 shuttlepod that were standard issue aboard vessels like the Enterprise D. (This one does look longer and a lot more angular, though.) While it's certainly possible that this is just a model designed by a superfan, it's also likely that someone aboard some future ship sent a team back to our time. Maybe they're marooned... in Vegas of all places. Who knows what this will do to the timestream.
