At Stora Dyrbo as you exit the safehouse (barn) down the ramp…to the right a little ways is a pair of doors on the ground like cellar doors. What is this and can you get in? See the pic where I was standing.
Gysbert’s map also says there is an alien in the other barn there…I see no alien??
Of course after years of playing this I may have experienced both already and just forgotten about it…ole geezer brain farts ya know. 
Hey,
there probably are ways to glitch in, but there’s nothing of interest. A hole.
Regardoing the Alien I don’t remember.
There is a note about the farmer trapping an alien in his barn it turns out to be a hunter .
It from the Mission Colonists.
Stora Dyrbo is the homestead where Uncle Calle lived. Calle and his nephew Freddie trapped a Hunter in the Barn. On the barn they painted a warning about an alien (they thought it was an alien).
Go and read it.
