"President Joe Biden on Tuesday [announced] plans to block expanded uranium mining around the Grand Canyon by declaring the area a new national monument.
The Baaj Nwaavjo I’tah Kukveni—Ancestral Footprints of the Grand Canyon National Monument will be a preserve about three times the size of Los Angeles in northern Arizona that will protect sites sacred to area tribes.
The more than 900,000-acre monument, created using the Antiquities Act, surrounds Grand Canyon National Park and is the fifth national monument Biden has created since he took office. It will also make permanent a 20-year ban on uranium mining in the area that the Obama administration imposed in 2012.
The monument will help the US atone for forcibly removing tribes from parts of the Grand Canyon when Congress declared it a national park more than a century ago, a senior White House official said, speaking to reporters Monday on condition of anonymity."
