Some kind of structure in the Waterfalls scene

I'm still trying to figure out what his scene even has to do with the overall film. It looks so out of place like a disc type UFO hovering over Niagara Falls. There is some type of structure though.

I noticed this a while ago. It looks to me like the UFO is coming up out of some kind of building or hangar. Could it be on the Spacejockey/Engineer planet? I'm willing to put a bet on that this structure is the Jockey/Engineers main base of operations.

This had been discussed before - I can't find the thread, but someone posted a picture of the actual waterfall, in daylight, and the rectangular looking chunk in the background is actually part of the natural landscape, clearly visible in the light of day

Yea, sadly, that mysterious structure is part of the natural landscape. Google Dettifoss, and you will see it. I myself want it to be the ancient alien temple. I guess it is not that kind of story.
