FOX D was located on a hill on a promontory about half-way between Broughton Island (FOX 5) and Cape Hooper (FOX 4), and about 50 miles from each.
The site was known as Kivitoo, after the former whaling station beside the fiord below the hill.
The installation consisted of the basic I Site provision of Modules, Garage, tower, and ancillary buildings (which were mostly Jamesway huts, inherited from construction days).
The tower was only 100 foot high, as this was sufficient for the Aircraft Alarm System transmission to clear the intervening terrain between FOX D and FOX 4. It was more than sufficient for the transmission to FOX 5 as there was only sea between FOX D and FOX 5. In fact the lights of FOX 5 could be seen with the naked eye on a clear night.
As there was a small coastal plain near Kivitoo village, a short airstrip had been built and DC 3s could land, albeit with only a light load. Heavy items had to come in by Sealift, or be dropped by parachute in winter on to the ice in the fiord.
DC 3s taking loads from DYE Lower to Cape Christian or to FOX 4would often drop off a light load at FOX D on the way back. Cape Christian, near Clyde River, was much further up the coast. A LORAN (LOng Range Navigation) System transmitter was installed there, and maintained by the US Coastguards.
At FOX D, the road from the airstrip to the Station was about five miles long, with an emergency hut about half way up.
The airstrip, but not the whole of the fiord, could be seen from the Station. So the weather observations for aircraft use had to be taken down at the strip, where any fog banks at all in the fiord could be seen and reported.
