"Alaska, it turns out, has never been mapped to modern standards.

“Mars is better mapped than the state of Alaska,” said Steve Colligan, president of E-Terra, an Anchorage mapping firm that specializes in aviation safety. Thanks to the Pentagon, the wilds of Asia and the Middle East are better mapped, too.

“We have this amazing map of Afghanistan. It’s the most modern geological map ever made,” said Kevin Gallagher, associate director for USGS Core Science Systems. “I would love to invest in America like this.”
