Yellowstone National Park remains one of the most popular national parks in the United States. However, a mountain at the park has now been given a new name after people protested. Originally, Mount Doane was named after a United States Army officer who led the massacre of hundreds of innocent Native Americans back in 1870. The new name will reflect the fact that the Native American tribes in the area had long been using the land associated with Yellowstone National Park as it has been renamed First Peoples Mountain.

The name change came after a unanimous decision U.S. Board on Geographic Names, according to an announcement from the National Park Service. Until this month, the mountain, which stands at 10,551 feet tall, was named after a man who led a deadly attack on the innocent people in the tribe Piegan Blackfeet in northern Montana. The massacre of Indigenous people left hundreds dead and occurred in 1870 after the Civil War freed the slaves.

For the rest of his life, Doane bragged about how he had led the killing of Native Americans and referred to the genocide as the Marias Massacre.
