Map below was composed from post war resources dated 1945/47,
and published in 1949. It shows the Admiralty / Nagai Heights area and the west half
of Camp McGill. The area south and east of the "Highway 236" symbol is the
west half of Camp McGill.
The "Otawa Airfield" area at the bottom of the map was/is the "Heights" area. The town of Nagai is directly west of the north end of the runway. The north half was retained and used by the military forces, and the south end and the balance of the field were turned into the housing area.
The northern camp boundary was pretty much straight north of
the "N" in the words Koto-Wan.
The camp area was real skinny there. It was bounded by the black road and then counter-clockwise just follow the road around till it heads north and the take a left at the triangle (traffic circle). Then the 236 highway and on out to the NW.
The southern camp boundary was at about the 5 or 5:30
position from the same "N". Right where the two small inlets come off the
bay (and the left one goes under the road).
The southern part of the camp area (south of the parade ground) was pretty much the navy area. The first N/S building (southern) along the blacklined shore was the hobby shop/snackbar/EM club. The area to the left (west) of the navy area was where the marines kept their amphibious vehicles (LTVs, LTV-As, and DUKWs).
It was a great place to live. Secure, no problems, no fence around the place, and a view to the S and W that was incomparable. To the south, the island of O'shima with it's active volcano (Mt. Mihara - I think) It wasn't a great volcano but it smoked and blew off steam with some degree of regularity.
