Adak is described by one blogger as "The End of America". His blog here does a really good job of tracking the history and current existence of Adak, which over the last 15 years has gone from a massive post-Cold War military facility to a run-downm, economically marginal community eking out a living from unpredictable fishing.

The latest event in the ongoing saga of Adak's power supply problems is that a new electricity supply utility has been assigned the job of electric power generation.

Here is another account of a trip to Adak by a visitor who spent over a week there, and got to talk to a lot of residents.
