I presume that anyone who hasn't been hiding in the backcountry for the past few months has heard that the Secretary of the Interior has been directed to review all National Monuments designated under the Antiquities Act since about 1990. The list of Monuments under review and directions on how to comment can be found here.
The comment period for all these monuments except Bears Ears (which expired May 26) expires at 11:58 pm ET on Monday, July 10. If you haven't commented, now is the time!
May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view--E. Abbey
