The Interior Department on Friday announced the 22 monuments in 11 states and five marine monuments that it is asking the public to comment on whether the federal land is being put to the best use.
Among the national monuments being reviewed are the Bain and Range in Nevada, Bears Ears in Utah, Berryessa Snow Mountain in California, Canyons of the Ancients in Colorado, Carrizo Plain in California, Cascade Siskiyou in Oregon, Craters of the Moon in Idaho, Giant Sequoia in California, Gold Butte in Nevada, Grand Canyon-Parashant in Arizona, Grand Staircase-Escalante in Utah, Hanford Reach in Washington, Ironwood Forest in Arizona, Mojave Trails in California, Organ-Mountains-Desert Peaks in New Mexico, Rio Grande del Norte in New Mexico, Sand to Snow in California, San Gabriel Mountains in California, Sonoran Desert in Arizona, Upper Missouri River Breaks in Montana and the Vermilion Cliffs in Arizona.
The marine national monuments include Marianas Trench, the Pacific Remote Islands, Papahanaumokuakea and Rose Atoll in the Pacific Ocean, as well as the Northeast Canyons and Seamounts in the Atlantic.
It's the first ever formal public comment period on the monument designations.
"The Department of the Interior is the steward of America's greatest treasures and the manager of one-fifth of our land. Part of being a good steward is being a good neighbor and listening to the American people who we represent," Interior Secretary Ryan Zinke said in a statement. "Today's action, initiating a formal public comment process finally gives a voice to local communities and states when it comes to Antiquities Act monument designations. There is no pre-determined outcome on any monument."
President Trump took executive action on April 26, ordering Zinke to review expansions or designations under the Antiquities Act since January 1, 1996 of all monuments that encompass more than 100,000 acres.
Interior will post an update on the Federal Register when the public comment period commences.
