This isn’t really new news – just a quick reminder. If you’re not following the U.S. Department of the Interior on Instagram, you’re missing out on some truly incredible photography, delivered free of charge to your smartphone every single day.

The DOI first started posting breathtaking photos on Instagram back in June of last year, and in just over a year the department has posted 671 photos and has amassed nearly 67,000 followers. The DOI, whose stated goal is to “protect America’s great outdoors and power our future,” provides some of the best content available on the photo-sharing site.

The feed features stunning nature photographs from a variety of photographers, and the DOI has even launched a contest involving its social media feeds. Called the “Share the Experience” photo content, the DOI is looking to find the best photos that showcase America’s public lands. The contest, which kicked off in May and lasts until December 31st, offers a grand prize of $15,000 and a bunch of runner-up prizes as well.
