Half-liquid land comes to an arbitrary point at the northern tip of Alaska, Point Barrow, a long tendril reaching into the Arctic Ocean where bowhead whales pass close to shore during their annual migrations. The Inupiat settled here more than a thousand years ago because it is such a good whale hunting spot, and that is still why they live here, dragging their skin boats miles out on the frozen ocean to wait for whales along the cracks in the ice pack. And, according to age-old tradition, here they still share the whales they catch among the entire community. Indeed, even visitors who show up on a Saturday in late June, during the Nalukataq, may be offered a piece of maktak (whale blubber and skin) and a chance to bounce high in the air in the blanket toss. Barrow is the northernmost settlement on the North American continent, above the 71st parallel, but that's not all that makes it unique. The town of 4,581 is cultural treasure. It's ancient, but it's also the seat of the North Slope Borough, a county government encompassing an area larger than the state of Nebraska, in which lies North America's largest oil field. The borough has everything money can buy for a local government, yet the people still must contend with crushing ice, snooping polar bears, and utter isolation. From these ingredients, they have concocted an extraordinary mixture of sophisticated modernity and wise tradition. Alaska's largest corporation is based here; its top executives are also subsistence hunters. At the Inupiat Heritage Center you could see, on successive nights, traditional dance in the Inupiaq language and avant-garde theater in the same language. Geography and the natural environment also make the place interesting. This is the most heavily instrumented and intensively studied scientific site anywhere in the Arctic. At the labs north of town, cutting-edge work on climate change takes place that could affect the whole world. The tundra around Barrow is dotted with lakes divided by tendrils of swampy tundra no more substantial than the edges of fine lace. On this haven for migratory waterfowl, the flat, wet land and the ocean seem to merge. Indeed, for all but a few months, it's a flat, frozen plain of ocean and land. For 65 days in the winter, the sun never rises. In the summer, it doesn't set. Ice recedes from the shore only for a few brief months. Such extreme geography is a magnet for visitors--people want to stand here, perhaps dip a toe in the Arctic Ocean. And then what do you do next? If you're on a package trip, you can see an Eskimo blanket toss and dancing, look at whale bones and maybe buy Native crafts, and see some other manifestations of traditional Inupiaq life amid a modern, oil-enriched town. If you have some time on your own, you can do even more: go out to the point and see polar bears; go to the Heritage Center, a living museum, and meet Inupiat people; or ride a bicycle out a road onto the tundra and get the measure of the place.
