Bill working its way through Congress wouldn't have allowed the Grand Canyon to be a national monument

Guardian - If a bill quietly working its way through the House of Representatives right now were law 111 years ago, Devil’s Tower wouldn’t have qualified as a national monument. Neither would the Grand Canyon, which Roosevelt protected as a monument in 1908 before it was made a national park. Nor would the Petrified Forest national park, Utah’s Zion national park, Bryce Canyon or many of America’s other legendary protected lands.

... The Upper Missouri River Breaks wouldn’t qualify as a monument under the bill, sponsored by Republican Rob Bishop of Utah. Like many monuments, it’s too big. The measure would cap the size of monuments and, critically, remove the ability to protect monuments of scientific interest, ruling out places selected for their unique formations like the giant sequoia trees of California and Wyoming’s Fossil Butte.
