US 89 and UT 12 are the two paved roads through
Grand Staircase-Escalante National Monument; other important routes are the Skutumpah Road between Cannonville and Johnson Canyon, Cottonwood Canyon Road between Cannonville and US 89, and the Hole-in-the-Rock Road between Escalante and Lake Powell.
In December 2017 the monument was reduced in size, and divided into three sections; the
Grand Staircase,
Kaiparowits and
Escalante Canyons units, however this change was reversed in 2021.
