Sand Creek Massacre. “One of the worst atrocities ever perpetrated on Native Americans.” Sand Creek Massacre. One of the worst atrocities ever perpetrated on Native Americans (Indians). Murdered in cold blood. “Sand Creek isn’t like Mount Rushmore or the geysers at Yellowstone,” says Karen Wilde, a Native American who works as tribal liaison for the Park Service. “You feel a presence here rather than just taking in the sights.” Sand Creek, she adds, has significance for all tribes, “because this is an example of what happened to so many native people across the land.” What really happened here? Ranger Bryant Mills will tell the story.
