Part of the historical site at Wounded Knee is up for sale. Should it be developed as a landmark or left in peace out of respect for the Sioux people who died there?
Almost as soon as the 1890 massacre at Wounded Knee was over, the battle to define what happened on that bleak December day began.
For decades afterwards, the official line from Washington was that the actions of the 7th Cavalrymen were heroic.
The White House and its allies in South Dakota had invested much political capital in seizing tribal land for US use, and using the army to quell Native American resistance.
What happened at Wounded Knee was promoted as a definitive end to these so-called "Indian wars", a final victory for the US government.
The administration of President Benjamin Harrison praised the military tactics used by the 7th Cavalry and awarded 20 of the soldiers Medals of Honor.
The New York Times told a different story, writing contemporaneously that the Native Americans had been "robbed when at peace, starved and angered into war, and then hunted down by the government."
At Wounded Knee, as many as 300 unarmed men, women and children were killed. And official reports from some in government criticizing the massacre were simply buried.
