Willy Roeoesli the uncle of Swiss farmer and charcoal maker Markus Wicki, covers a pile of tree trunks with coal dust which will be used to make charcoal near the remote village of Romoos, central Switzerland June 10, 2008. The Wickis are one of few mountain farming families in the region of the Napf mountains who have carried on the generations old tradition of natural charcoal making, using a slow-burning pile procedure. The pile, once it is lit, needs to be constantly checked every three hours during the process which takes up to three weeks. REUTERS/Michael Buholzer
