October 27, 1937: "When the last lonely forest fire lookouts climb down from their isolated vantage points and haul down the flag of the land over which they have kept summer vigil there will be one exception. A.C. Mattison of Okanogan, Wash., holds the distinction of being the only United States forest service lookout posted on foreign soil. He is lookout at monument 83 on the Canadian boundary of the Chelan national forest. The station was built across the boundary line in Canada under special privilege granted by the British king. Mattison looks out upon a grand and inspiring view from his lonely perch. The largest primitive area in the north Pacific region, the north Cascade primitive area, lies just to the south. To the north is the Canadian landscape, which is similarly rich in rugged and spectacular beauty. Deer near Mattison's station became so friendly this season that he was able to touch them and one large buck actually licked his face, he reported to regional headquarters here. The Canadian government requested that the American flag not be flown from Mattison's lookout station, a request that was complied with. However, Mattison asked for a British flag, but failed to receive it so a 125-foot flagpole was erected in front of the lookout house which is several feet from the international boundary on the American side and the Stars and Stripes fluttered from the top throughout the season."
