PART 3: TOUR OF PRUDHOE BAY AND KUPARUK OILFIELDS.

The article provides detailed descriptions of tour stops in the Prudhoe Bay and Kuparuk oilfields, the two largest oilfields in the U.S., located in northern Alaska, and illustrates prominent permafrost-related phenomena and human adaptation to the permafrost environment. Together with four adjacent oilfields, they have contributed about 20 percent of the domestic oil production in the U.S. The first stop is Deadhorse, where road access to the Arctic Ocean and the oilfields is restricted.
