These are FEMA camps in the State of Alaska - for a complete list please refer to the list of camps page.
These camps originate from many combined lists of supposed camps from all over the Internet. For more information see the FEMA camps page.
There are a supposedly a total of 4 FEMA camps in Alaska; in reality none of the listed locations are FEMA camps, or prisons, or even former POW camps. There is nothing at all out of the ordinary.
Air Force Bases: 2
Military Forts: 1
Nothing at all: 1
Southeast of Fairbanks. Operation Garden Plot facility.
There's no evidence of a FEMA camp, POW camp, federal prison, and so on at Eielson AFB, in fact the only "source" you can find for such a thing are lists of so-called FEMA concentration camps.
Northeast area of Anchorage - far end of base. Garden Plot facility.
Same story as above: there's no evidence of a FEMA camp, POW camp, federal prison, and so on at Elmendorf AFB, in fact the only "source" you can find for such a thing are lists of so-called FEMA concentration camps.
East of Fairbanks
Same story once again: there's no evidence of a FEMA camp, POW camp, federal prison, and so on at Ft. Wainwright, in fact the only "source" you can find for such a thing are lists of so-called FEMA concentration camps.
East of Anchorage. No roads, Air & Railroad access only. Estimated capacity of 500,000
"Wilderness" is pretty vague, the cited location is pretty much just a regular remote area. There are some roads, some buildings, and so on. The idea that just random wilderness could be considered a FEMA concentration camp is just stupid, because no evidence at all exists to say this or that remote location is meant to hold anyone, especially not 500,000 people.
