On a day imbued with painful significance for many Native Americans, hundreds of people demonstrated against the Dakota Access Pipeline (DAPL) in North Dakota and beyond on Thursday. From a protest about 300-strong in Mandan, North Dakota, to an attempt by Indigenous water protectors to reclaim sacred sites threatened by the pipeline, to a solidarity rally in Portland, Oregon—plus widespread calls for donations to Standing Rock to mark Thanksgiving Day—resistance to the 1,172-mile "black snake" remained fierce on what some refer to as the Day of Mourning.
