A viral Facebook prank has convinced a lot of people that this photo shows the anti-pipeline protest in North Dakota. It's a hoax.

What the photo actually shows is the iconic Woodstock music festival in 1969.

Eldridge's post is tagged with a fake business page on Facebook called "Pipeline! North Dakota" which may have contributed to its spread.

Eldridge copped to the hoax in the comments on his photo. "I made the news for a viral hoax picture of the protest lol," he wrote.
