The Bolivian government has appealed for help after the snow left thousands stranded.
The snow took farmers and tourists by surprise in the usually dry highlands of Potosi – a vast area in the south-west of the country.
The Bolivian government says it needs helicopters to drop aid to isolated communities and heavy machinery to clear the roads.
Roads remain closed, and rescue efforts have been hampered by the poor weather. The storm left many farmers with lost crops and more than 50,000 llamas and alpacas are reportedly without food as their pastures are covered by snow.
