A free imagination of what may have happened behind the high walls of the US-army base in Seoul's Yongsan district at some day in the past . This imagination is based on the fact, that lots of oil is found in groundwater probes near the army base and on a case of dumping agent orange by US-soldiers in Korea in the late 1970ties.

The diorama was shown at the exhibition "yongsan garrison investigation exhibition - reservation area" of group Gate 22, who do artistic research about the future of the yongsan garrison area, after the us-army will move to the Pyeongtaek garrison 70km to the south.
