Workers building a new cable-car station in La Paz, Bolivia uncovered a trove of archeological treasures dating back to 1,000 years before the Spanish conquest. The exciting historical discoveries include ceramic utencils and pottery from the Tiwanaku civilization. No skeletal remains have yet been found, but archeologists expect to uncover more items that could shed new light on the pre-Columbian civilization. Dimitri O'Donnell reports from La Paz. teleSUR
