The Grand Staircase refers to an immense sequence of sedimentary rock layers that stretch south from Bryce Canyon National Park through Zion National Park and into the Grand Canyon. This huge area rises in broad, tilted terraces and was declared a National Monument during the Clinton administration in 1996.

With approximately 7,600 km² it is the largest US National Monument and stretches from the towns of Big Water, Glendale and Kanab, Utah in the Southwest, to the towns of Escalante and Boulder in the Northeast. There are three main regions: the Grand Staircase, the Kaiparowits Plateau, and the Canyons of the Escalante.
