Built in the 1970s after oil was discovered at Prudhoe Bay (1968), the 48-inch diameter, 800-mile pipeline links Prudhoe Bay on the Arctic Ocean with the terminal at Valdez, the northernmost ice-free port in the Western Hemisphere. The flow from this pipeline accounts for roughly 20 percent of U.S. oil production annually.

The coordinates are correct. Closest town is Coldfoot, Alaska.
Koyukuk is 240 miles southwest, and not even on the pipeline route.
