National monuments are unique among the special and protected land designations on federal public lands, because they are created pursuant to a special, but narrow, grant of authority to the president to regulate federal public lands. Under the Antiquities Act, the president can essentially sign a proclamation to protect certain areas as national monuments.

Since its enactment, the Antiquities Act has been used more than 150 times to designate and protect national monuments. And some of our western icons — including Grand Canyon National Park, Bryce National Park, and Zion and Arches National Parks — began life as national monuments. Others have remained national monuments for many decades and have become world-renowned, such as Grand Staircase-Escalante National Monument.

The Trump administration shrank the boundaries of Bears Ears by 85% and cut the size of Grand Staircase-Escalante by half, opening those lands to mining and drilling. The administration’s plans included destructive industry practices, such as chaining forests with waist-thick chains and carving up landscapes for new roads.

Earthjustice sued to protect Bears Ears and Grand Staircase-Escalante, representing nine organizations, and was co-plaintiff with NRDC (the Natural Resources Defense Council) and the Southern Utah Wilderness Alliance.

In 2021, President Biden restored the original boundaries of Bears Ears, Grand Staircase-Escalante, and Northeast Canyons and Seamounts Marine National Monuments.
