The buildings at the end of the video looked like they were covering 3 generators with two thousand gallon fuel tanks most likely used to power the area around them. And the buildings that we visited first looked like houses that the people who operated the generators could stay in during bad weather. Thank you so much guys for watching my videos from Alaska I put a lot of work into editing them and I do it so I can look back on it in the future and for you guys too. (The information I have was not fact checked or found with any research it’s just my best guess. But if you do I find out what it is please let me know in the comments).
