The rooftop of Europe

My grandmother always told me that on sunny days, if lucky enough, we could have a glimpse of Mont Blanc from our house.
I never thought it would be possible on a winter day but I was wrong, as this picture was taken from our living room in December 2011, and the snowy top of Mont Blanc is right in the center of the photo! The sky was indeed very clear and blue that day, and the weather quite warm for this time of year. Only the trees show it was winter.
