File Description: Cape Hooper is around 60 miles north of Kivitoo (FOX-D) and 140 miles south of Clyde River CYCY on the northeast-facing coast of Baffin Island. FOX-4 is still in use as a new and mostly-unmanned North Warning System site was established there in 1990 before the DEW line station was closed in 1991. Actually the DEW line station was not "closed" as such, they just stopped using it. The site of FOX-4 is on the top of a bump at the end of one of many long promontories that stick out into the Davis Strait between Baffin Island and Greenland, close to the far eastern end that is called Cape Hooper. There is a gravel runway to the west, down at 65' ASL; it is only just over 3,000' long and most material was delivered by sea to the beach at the southern end of the runway. The runway is signed as
"324T - 144T" as this is Northern Domestic Airspace where all runways are signed "true" and not "magnetic"; it is 013/193 magnetic with a huge magnetic variation of 48.9 degrees in this area where the magnetic field is mostly vertical, and so useless for navigation.
