In early 2016, the Dakota Access Pipeline was near completion when members of the Standing Rock Sioux Tribe in North Dakota began their protest. The line was to go under the Missouri River at Lake Oahe, next to the Standing Rock Reservation. Members claimed it would threaten their water. They gathered, at first by the hundreds and within months by the thousands. Clashes with law enforcement were inevitable. The protests drew international attention. Even celebrities stood in solidarity. The standoff at Standing Rock would eventually reshape the conversation for environmental projects that cross Native American lands.
