Twitter is showing off its power as a source of news and commentary with a showcase of 2013′s biggest events as seen on, where else, Twitter.
Inside Twitter’s year-end feature is a roundup of the most popular images shared by the U.S. Department of the Interior, which manages the country’s national park system. The images are above, and you can click through to the original post on Twitter for full stats on sharing.
During the U.S. government shutdown in October, users of Instagram took to their smartphones to post images of national parks that had been closed because of political battles in Washington, D.C.
Twitter’s roundup also included National Geographic’s tweets and images from the brand’s 125th anniversary year.
