State and federal officials are now focusing on cleaning up the area where the main Dakota Access Pipeline protest camp was located.
It’s along the Cannonball River, on Army Corps of Engineers land north of the Standing Rock Reservation.
Crews have been working to clean up the debris. They’re dismantling structures, hauling out abandoned cars and filling dumpsters with garbage.
"This isn't just high school kids picking up garbage in a ditch along teh road," Gov. Doug Burgum told reporters at a Mandan news conference.
