Water is scarce in Utah and yet still today, as in the past, shapes Zion National Park. According to the National Parks Service website, Zion was once a large basin near sea level. Varying forms of sediments washed down with the rains, piling on top of one another. The land went through many different fluctuations. It was a shallow sea bed, then a coastal plain, and then a sandy desert. As the weight of each layer compressed upon the previous layers and mixed with water that seeped throughout, it solidified and oxidised the materials, forming the “lines” in the stone we see today.
