A huge manmade mountain measuring 420 meters long, 270 meters wide, 38 meters high and elliptical in shape was planted with eleven thousand trees by eleven thousand people from all over the world at the Pinziö gravel pits near Ylöjärvi, Finland, as part of a massive earthwork and land reclamation project by environmental artist Agnes Denes
Inspired by the many hiking trips that the two students from China have enjoyed during their studies at ETHZ, the entry is based on the idea of a hypothetical mudflow in the Swiss Alps burying a village.

Sunlight is being transmitted through the columns into the subterranean space, where they illuminate a poetic memory of the former rooms in the buried houses.
