National Geographic is dipping its toes into social waters with its latest photography project.
In honor of its 125th anniversary, the non-profit has joined Tumblr to showcase "FOUND," a collection of rare photos from the National Geographic archives.
According to the site, most of the photos have never been published, and were rarely seen by the public until now. National Geographic hopes digitizing the archive will also help identify the original date or location of the photos, since many are missing that information.
"This is just the beginning of a great adventure," the non-profit writes on its new site.
Viewers are encouraged to share any information about an image by emailing National Geographic. More stories and photos, like the incredible ones shown below, will be added along the way.
