Which national park in Utah is famous for its hoodoo rock formations?

The Utah national park famous for its hoodoo rock formations is Bryce Canyon National Park.

Bryce is not actually a single canyon. Its signature landscape is a series of giant amphitheaters cut into the eastern edge of the Paunsaugunt Plateau. Thousands of slender rock spires, called hoodoos, rise from these amphitheaters in dense, maze-like formations. Frost wedging and stream erosion gradually shaped the Claron Formation’s sedimentary rocks into the pinnacles visible today.

The rocks’ red, orange, yellow, and white colors come from minerals in the rock, including iron oxides. Bryce’s high elevation also helps drive its freeze-thaw weathering: water enters cracks, freezes, expands, and gradually pries the rock apart. The process continues today, even though individual hoodoos change very slowly on a human timescale.

The area was named for Ebenezer Bryce, a Mormon pioneer who settled nearby in the 1870s. President Warren G. Harding established Bryce Canyon as a national monument in 1923, and Congress redesignated it as a national park in 1928. A common mix-up is Zion National Park, which is better known for immense canyon walls rather than Bryce’s clustered hoodoos.
