The sun's pretty bright up there and it reflects pretty effectively on the snow and ice. I suspect this can cause tanning as well as any beach.

Reply:"Looking at Alaska, one would think that the native people should be pale as ghosts," One of the reasons they're not is that these populations have not lived in the region very long in terms of geological time. But more importantly, their traditional diet is rich in fish and other seafood. They've consumed huge doses of vitamin D, so they haven't had to undergo the same reduction in pigmentation that would otherwise be required at such high latitudes. "What's really interesting is that if these people don't eat their aboriginal diets of fish and marine mammals, they suffer tremendously high rates of vitamin D-deficiency diseases such as rickets in children and osteoporosis in adults,"

Reply:Because whatever sunlight they get at the North Pole, it is reflected right back at them from the snow and ice, so they are perpetually being "tanned" and have darker skin than one would expect.
Reply:Because they were relatively new to the area historically speaking. They came across the land bridge from Asia through Russia . They're more Asian than Alaskan.
Reply:The reflection of the sun off of the snow is what causes them to get that healthy glow.
