Mount Doane will now be named First Peoples Mountain after a unanimous vote by the US Board on Geographic Names, the National Park Service declared Thursday.
The 10,551-foot peak in southeastern Yellowstone in Wyoming had been named after the explorer, who in 1870 assisted to lead an attack on a band of Piegan Blackfeet in northern Montana.
Doane boasted for the rest of his life regarding what became known as the Marias Massacre.

The Great Plains Tribal Chairman's Association, an organization of tribal chairmen of 16 Sioux tribes from the Dakotas and Nebraska, required that Mount Doane be renamed in 2018.
"This name change is long overdue. We all agreed on 'First Peoples' Mountain' as an appropriate name to honor the victims of such inhumane acts of genocide, and to further remind people of the 10,000-year-plus connection tribal peoples have to this sacred place now called Yellowstone," Piikani Nation Chief Stan Grier announced in a statement Wednesday.

The attack in response to the claimed slaying of a white fur trader killed no less than 173 American Indians, including many women, elders and children suffering from smallpox, Yellowstone officials said in a statement.
"We're not against certain names," William Snell, executive director of the Rocky Mountain Tribal Leaders Council, announced in 2018.
