The dramatic landscape of Gates of the Arctic National Park and Preserve is one of the wildest in the National Park System.
Gates of Arctic National Park and Preserve

Cold as ice. That pretty much sums up permafrost at Gates of Arctic National Park and Preserve in Alaska. This photo from the park staff shows a wonderful example of permafrost; you can easily make out the frozen, and unfrozen, soils. With such a short summer season, much of the ground in the Arctic stays permanently frozen, creating conditions for shallow root systems and low growing plants, the park says.
