A primitive jeep trail led to Campbell Garrison and Campbell Airstrip through the birch woods. As the airstrip took shape, the soldiers began to adapt their surroundings for the long hard winter ahead. They built a guard shack and barracks huts out of saplings and then insulated them with double layers of sod. After the first few months, the Campbell Garrison looked more like a Boy Scout camp with tents and improvised shelters, rather than a military installation. The huts kept some of the snow off and could be heated.
Digging fortifications became another priority before the ground froze. Anti-aircraft gun emplacements, machine-gun nests, and foxholes ringed the airstrip. More foxholes protected troops near offices and quarters. Those entrenchments, now mere depressions among the trees, are still visible reminders of World War II.
As soon as possible, Quonset huts made up of arced steel sections replaced tents and temporary huts. United States Army Air Force and Royal Canadian Air Force planes and crews used the Campbell Airstrip before flying on to the Aleutian Islands.
