A group of tourists observes a subsidence at Rico Hill ("Sumaj Urqu" in Quechua language, meaning beautiful or majestic hill) in Potosi, Bolivia, on September 21, 2010. Rico Hill is one of the biggest silver deposits of the world and a symbol in the Bolivian emblem. Five hundred years of exploitation have left over 600 pitheads and 90 kilometers of tunnels.
