Sandstone formations, Zion National Park

Référence de la vidéo 11940007
These fractured blocks of sandstone in Zion National Park, Utah, are caused by the repeated freeze-thaw cycle of water that has seeped into rock cracks, a process referred to as frost wedging. Zion is part of the Grand Staircase, an immense sequence of sedimentary rock layers that stretches 200 kilometres from Bryce Canyon to the grand Canyon in the American Southwest. Here in Zion, the layers were laid down over a 150 million year period before they were thrust upward by the forces of plate tectonics and carved by erosion. Famous for its spectacular scenery, the 24 kilometre-long valley attracts more than three million visitors from throughout the world each year.
