Falling rocks cut off popular resorts Val Thorens, Les Menuires and St Martin and ski enthusiasts were left stranded in a 50-mile tailback. Holiday coaches were stopped from entering and leaving the resorts in the Tarentaise Valley after authorities ruled the N117 road was too dangerous for large vehicles to use on Friday morning.
