Birkenau 1979. This tree would fall from time to time and was periodically raised by then Birkenau caretaker Urbaniak. It was in "Kanada", the place where all the possessions of those taken off the trains were stored in many barrack/warehouses for shipping to Germany. They were destroyed in advance of Russian liberation of the camp. It was nicknamed thus because it was a place of abundence. See U.S Memorial Museum photo archive: Go to photo archive and search for Kanada/Birkenau. These are actual photos taken by the SS.
