What an awesome video. Enjoy this compilation of Mt. Washington, shot in all seasons from January of 2013 through January of 2014. According to the Mount Washington Observatory, all time lapses were shot with a Canon 10d or a Gopro Hero 2 at various exposures and intervals.

Since 1932, the Observatory has been observing Mount Washington's incredible extremes, conducting scientific research, educating the public about the science of weather and climate and amassing one of North America's longest and most unique climate records.

Mount Washington Observatory is a nonprofit, membership-supported research and educational institution with a mission to advance understanding of the natural systems that create Earth's weather and climate.
