Got this from Reddit.

Does the loop around the UFO wagon look like a point of interest?
Also that wagon is depicting the lighthouse.....
Actually, I saw that image and thought the same thing... I've pretty much lost my mind already, but at this point I have no idea... although from the satellite map (in the digital manual) the light house does look like a red dot.
I tried overlaying more or less that same image of the camp (as above) over a picture I took of the main in-game map and tried to align it with other points on the map... I got squat... (well without jumping to wild conclusions)... I'm starting to think that if this is a model/map of some area of LS or Blain County, it is seriously deformed, stretched or caricatured...
At this point the idea that the lighthouse might be what the dot with the UFO/Station wagon represents does not sound so bad.
Then again I'm pretty sure that just as in the previous GTA games, there has to be encounter, mission, or event that has to be the trigger to open, or access what the location provides... even if we find the location (for all we know it could have been found a thousand times already)... without knowing what the trigger is we really have nothing.
I'm really starting to think it may be a character/NPC whom nobody has met or talked to yet... or worse yet keeps killing.
I spent about an hour and a half this morning looking at/comparing the symbols around the camp to crop circles... and searching around google for some sort of "crop circle" decoder, or key... (no, I don't believe in them)... I was hoping that maybe Rockstar had made some key, downloadable font, or maybe even site... but I got nothing but a headache and a distinct impression there are some REALLY-REALLY-REALLY f**ing crazy people out there in UFO/conspiracy land.
I'm sure it has been said before, but those circle based characters around the perimeter of the camp appear to be based on crop circles... they also probably don't spell out anything either, so that was an even bigger waste of time.
