This building has no visible floor, instead you tread on loose soil. I believe conveyors were fed through each of these small windows and this building was involved in the production of some of the smaller caliber shells used during the war.
The Kingsbury Ordnance plant sat upon land acquired by the us government during ww2. some 13,000 acres were designated for this facility and it was operated throughout the war and then once again reopened for the Korean conflict. This is one of my favorite abandonments to visit.
