Fodor's Review

If you're hiking the wildflower-carpeted tundra around Kotzebue, you are entering a living museum dedicated to permafrost, the permanently frozen ground that lies just a few inches below the spongy tundra. Even Kotzebue's 6,000-foot airport runway is built on permafrost—with a 6-inch insulating layer between the frozen ground and the airfield surface to ensure that landings are smooth.
