Look closely at this UFO and you will see its partly cloaked. What looks like smoke, is actually the hidden parts of the ship becoming visible. This UFO either just came out or was about to enter an alien base that would be about 4-5 miles below the ground. That is the only possibility for an alien craft to be hovering in a desolate location for so long.
There are a lot of aliens that prefer the dryer hotter climate like the tall grays and the short grays, and the tall whites.
