The following canyons will no longer be located within the Grand Staircase-Escalante National Monument.
This is speculation from the recently leaked draft of the modifications.
All of these canyons are still in Wilderness Study Areas. WSAs require an act of congress to revoke the designation and no new construction or mechanized vehicles are allowed.
I lined up the leaked draft image map with the current (former?) border and added all the Escalante canyons from the Super Amazing Canyoneering Map.
In the image below, it looks like the southern border of Escalante Canyons National Monument is Egypt Road so all of the Egypt canyons and anything over there that drains into 25 Mile Wash is no longer part of any national monument.
Note that Fence Canyon and all canyons on the opposite side of the Escalante River are in Glen Canyon National Recreation Area and were never part of GSENM.
All the canyons south of Egypt road on Hole-in-the-Rock Road are no longer within a national monument. This includes Spooky and Peek-a-Boo and many other canyons that drain into Coyote Gulch.
I also find it unusual that nearly all of Hole-in-the-Rock Road was removed from the monument.
I’m not quite sure about which of these slot canyons are within a national monument still. Catstair Canyon that is north of Buckskin Gulch and The Wave is definitely out now.
