D'Arcy at that time was just inside the 100 miles "quarantine" zone from the Coast beyond which all Japanese had to be evacuated, but because the D'Arcy-Birken valley (known as the Gates Valley or Birken Valley) and the Pemberton Valley in those times had no road access to the Coast, its physical isolation made regulations placed on the Japanese somewhat lax in comparison to the internment camps in the Kootenays.
