Grand Staircase–Escalante Monument shrinks: 60-day reopening clock at 9 a.m.

A presidential proclamation posted by the White House on July 13, 2026 modifies the boundaries of Utah’s Grand Staircase–Escalante National Monument under the Antiquities Act—shrinking the monument to two reserved units and setting a specific 60-day reopening clock for the lands removed from the monument reservation.

The proclamation names the remaining monument areas as the Canyons of the Escalante Unit and the Kaiparowits Horizon Unit, totaling about 181,541 acres. Lands previously reserved under earlier monument proclamations that fall outside those mapped unit boundaries are excluded from the monument.

How big the change is

The White House fact sheet says the monument is reduced from approximately 1.87 million acres to approximately 181,500 acres. In the proclamation’s own findings, the boundary change excludes approximately 1.69 million acres as unnecessary or disadvantageous to the proper care and management of the protected objects.

The reopening clock: 9:00 a.m. after 60 days

The proclamation sets the key timing mechanism: at 9:00 a.m. eastern daylight time, on the date that is 60 days after the date of this proclamation—the public lands excluded from the monument reservation are to be “open” to specific categories of federal actions, subject to valid existing rights, existing withdrawals, and applicable law.

In the proclamation’s terms, excluded lands may be opened to:

• Entry, location, selection, sale, or other disposition under the public land laws
• Disposition under laws relating to mineral and geothermal leasing
• Location, entry, and patent under the mining laws

The proclamation also says “appropriation” of lands under the mining laws before the specified restoration date and time is unauthorized, and that attempted adverse possession would vest no rights against the United States.

What stays protected—and what Interior/BLM must do next

The two reserved monument units remain under monument protections, but the proclamation directs the Secretary of the Interior—through the Bureau of Land Management (BLM)—to maintain a management plan, promulgate management regulations, and conduct public involvement, including consultation with federally recognized Tribes and State and local governments.

For practical access, the proclamation says the management plan should take into account priorities including:

• Providing appropriate access and facilitating livestock grazing
• Maintaining and improving public access for recreation and hunting
• Educational experiences related to the monument’s natural and human history

It also calls for a transportation plan aimed at maximizing public access by designating roads and trails where motorized and non-motorized vehicle use will be allowed, while providing appropriate maintenance.

Who is affected—and what to watch next

In practical terms, ranchers and grazing permit holders, recreation and hunting users, tribal governments, and state and local governments are the groups most likely to monitor how these rules get implemented. Axios also reports the reductions affect more than 90% of each monument’s area.

The next meaningful federal steps will be how BLM and the Department of the Interior finalize the management plan and transportation/access decisions for the two reserved units—and, once the 60-day clock runs, how quickly and how broadly decisions under public-land and resource authorities move forward for the excluded lands, while staying within “valid existing rights,” “existing withdrawals,” and other applicable legal limits.
