The most striking geological feature of the Colorado plateau is its tectonical stability. In contrast to the surrounding mountains of the Sierra Nevada to the west and the Rocky Mountains to the east only minor folding took place during the uplifting process. Also belonging to the Grand Staircase of the Escalente, Zion Canyon lies at the western boundary of the geological staircase. This area exposes the oldest rocks of Zion. The water runs like a blue band at high speed through this crack in the deep red bedrock.
