(FILES) Termaine Edmo, Environmental Advisor to the Blackfeet Nation, expresses the importance of the land while performing a prayer ceremony at the Jackson Glacier Overlook in Glacier National Park, Montana on October 20, 2023. Most national parks were set up in areas that are Indigenous ancestral lands. From the 19th century onward, Native Americans were expelled from them or forced to cede them via treaties with unequal terms. Edmo, 35, takes part in the Native America Speaks program which each summer brings members of her tribe, the Blackfeet Nation, to share their history with visitors to Glacier National Park. But the activist, her eyebrows furrowed, speaks harshly of those who administer the land "stolen" from her people, where plant harvests remain rationed. "They're still oppressing us," says Edmo, whose license plate begins with the letters "DECO," for "decolonization." (Photo by JOSH EDELSON / AFP)
