A UN special rapporteur has called for the US to restore tribal lands, including the Black Hills of South Dakota, site of Mount Rushmore.
James Anaya announced the recommendation at the end of a 12-day tour, during which he met tribal leaders and government officials.
“The sense of loss, alienation and indignity is pervasive throughout Indian Country,” Mr Anaya said.
He met with tribes in seven states on reservations and in urban areas.
The trip, Mr Anaya’s first tour of Native American lands, was to determine how the United States is fairing on the UN Declaration on the Rights of Indigenous Peoples.
President Barack Obama endorsed the declaration in 2010, reversing a previous US vote against it.
