Top Big Pictures in 2013

We've published about 150 entries this year, covering everything from the bleakest of news events to the glory of nature. By calling them 'Top', we don't mean to imply anything about the stories covered by the stunning photographs - just that the most people looked at what we published during 2013. Here's the Top 10 (which includes some topics published in previous years):

Terror at the Boston Marathon	The Natural World
National Geographic Photo Contest 2012	Russia in Color, A Century Ago
A Soldier's Eye: Rediscovered Pictures from Vietnam	Best Nature Pictures of 2012
2013 National Geographic Photo Contest entries	125 Years of National Geographic
