Oymyakon valley, Russia
By Maxim Shemetov
One loses all bearings when faced with the shroud of white that obscures all things mid January in the Siberian city of Yakutsk. Only the traffic lights and gas pipelines overhanging the roads help you to find your way. Wrapped in frosty fog the city life seems frozen in a sleepy half-light. It is -48 C (-54 degrees Fahrenheit) outside.
