chevron refinery
i liked the contrast between the beautiful natural landscape and the harsh industrial plant producing petrol diesal, kerosene, jet fuel etc
i've recoloured the photo above slightly in an attempt to give it a more eery look. don't think it worked, but these things are always worth a try !
I like it - looks like the cover of a 1970's sci-fi novel: The Spires of Chevronia or something.
I think that last photo worked very well. It has a science fiction look like a settlement on another planet. I like the other comment for a name of the place.
