Paunsaugunt Plateau
From Wikipedia, the free encyclopedia
The Paunsaugunt Plateau (pronounced "PAWN-suh-gant") is dissected plateau, rising to an elevation of 7000 ft-9300 ft (2100 m-2800 m), in southwestern Utah in the United States. Located in western Garfield County, it is approximately 10 mi (16 km) wide, and extends southward from the Sevier Plateau approximately 25 mi (40 km), terminating in the Pink Cliffs at the southern end.
It is drained by the East Fork Sevier River which flows northward on the plateau, to the meet the main branch (Sevier River) which flows in a valley along the western side of the plateau. The plateau is highly dissected along the eastern flank, which is drained by the Escalante River in the Colorado River watershed, and is protected as Bryce Canyon National Park. The plateau essentially marks the southeastern extreme of the Great Basin. Much of the plateau is part of Dixie National Forest.
Geologically the plateau was created approximately 10-15 million years ago by an uplift on the larger Colorado Plateau. The uplifting caused the formation of joints along the side of the plateau. Susequent erosive forces, especially along the eastern side in Bryce Canyon National Park, have resulted in the creation of strange rock formations called hoodoos which are the hallmark of the park (see Geology of the Bryce Canyon area).
The plateau receives approximately 200 in (500 cm) of snow per year and experiences approximately 200 days of freeze-and-thaw cycles.
Utah's Highway 12, an All-American Road, climbs to the top of the Paunsaugunt Plateau.
