For you blue

Did a 6 km morning skiing before breakfast and admired how the dawn approached, and the dark blue of the sky turned lighter as the sun was getting closer and closer to the horizon. At the moment of this pic, it was still below the horizon. It was -11C so quite ok for cross-country skiing especially as the ski-track tractor had laid a new track even earlier in the morning on top of the snow that had come down yesterday evening (5 cm on the car at least).

Mrs preferred the warm bed instead.
