As so often is the case you make your own luck. We left Chamonix in thick mist and slippy roads and headed for Verbier. We headed for the Savoleyers side. As we rode the tiny bubble we popped out of the fog to clear blue skies. I called Air Glacier and they sent a helicopter to take us all to the summit of the Rosa Blanche where we landed in perfect conditions. We skied down to Siviez where we had a late lunch before picking up the lift system that took us back over to Verbier and back down into thick Fog.
