North Dakota Governor Doug Burgum holds a press conference announcing plans for the clean up of the Oceti Sakowin protest camp onFeb.22, 2017 in Mandan, North Dakota. Protesters and campers against the DAPL pipeline, at times numbering in the thousands, are now down to under a hundred.
Most of the Dakota Access pipeline opponents abandoned their protest camp Wednesday ahead of a government deadline to get off the federal land, and authorities moved to arrest some who defied the order in a final show of dissent.
The camp has been home to demonstrators for nearly a year as they tried to thwart construction of the pipeline. Many of the protesters left peacefully, but police made some arrests two hours after the deadline.
Earlier in the day, some of the last remnants of the camp went up in flames when occupants set fire to makeshift wooden housing as part of a leaving ceremony. Authorities later said about 20 fires were set and two people — a 7-year-old boy and a 17-year-old girl — were taken to a Bismarck hospital to be treated for burns.
