Background info Edit
According to a 21st century-era political map of Earth, Anchorage was an United States city on the coastline of the Gulf of Alaska. This Central Intelligence Agency, which was seen in the remastered "The Cage", was published either in April 2007 or September 2008. The difference, which was not noticeable at the resolution of the image from the episode, was the addition of Kosovo, which gained its independence between the releases. Neither of the labels for Anchorage and the Gulf of Alaska were legible to the viewer.
It was possible that Anchorage was on a 20th century-era political map of Earth used in the original "The Cage". However, due to the poor quality of the image and the inability to access the source material, this was far from certain.
