Pictured: The thick fog across the mountains at sunrise
This thick fog looks more like rolling ocean waves as it envelops an entire mountain range. The fog was more than 1,000m high and easily covered the trees and hills that are part of the Swiss Jura mountains.
The sunrise colours the sky a beautiful yellow but the sun's rays have not yet reached the clouds, which are a contrasting blue. Sandra Schaenzer, 47, hiked to the top of the Swiss Jura mountains, in Baselbiet, Switzerland, at 6.15am to be able to photograph the phenomena. SEE OUR COPY FOR DETAILS.
