More information comes to light regarding the pipeline near Standing Rock, ND, courtesy navajo on The Daily Kos:
In a Friday letter to President Obama, the United States Department of Justice, Department of the Interior, the Army Corps of Engineers, a coalition of more than 1,200 archeologists, museum directors, and historians from institutions including the Smithsonian and the Association of Academic Museums and Galleries denounced the deliberate destruction of Standing Rock Sioux ancestral burial sites in North Dakota.
As archaeologists, anthropologists, historians, and museum workers committed to responsible stewardship, we are invested in the preservation and interpretation of archaeological and cultural heritage for the common good. We join the Standing Rock Sioux Tribe in denouncing the recent destruction of ancient burial sites, places of prayer and other significant cultural artifacts sacred to the Lakota and Dakota people.
On Saturday, September 3, 2016, the company behind the contentious Dakota Access Pipeline project bulldozed land containing Native American burial grounds, grave markers, and artifacts–including ancient cairns and stone prayer rings. The construction crews, flanked by private security and canine squads, arrived just hours after the Standing Rock Sioux tribal lawyers disclosed the location of the recently discovered site in federal court filings.
Former tribal historic preservation officer Tim Mentz called the discovery of the site “one of the most significant archeological finds in North Dakota in many years.”
