Unmanned gas station in Deadhorse. The most expensive gas in the US, ironically, in an oilfield! The yellow thing is to catch spills. In the oilfields, more than a tablespoon is considered a spill, which must be reported to Alaska Clean Seas, who clean it up. The oil companies are fined for each spill. To an untrained eye, the whole place did look very clean, with all kinds of birds nesting on the tundra at the side of the road.
