Images from a photography overnight at the Mt Washington Observatory. Mt Washington at 6,288 feet is the home of the "World's Worst Weather". We were out trying to photograph in -20 deg f and gusts to more than 100mph. We were lucky, however, to have a broad range of conditions,from wind-whipped fog to brilliant , crystal clear sunshine. An incredible experience as much for the struggle with the elements as for the unique photographic opportunities.
