Sedimentary Slope

Photo: Zion rock layers
Erosion's artistic side can be seen in sedimentary rock layers in Zion National Park, Utah. After mud, gravel, and sand sediments were deposited and formed rock layers over time, uplift raised the region. Erosion then began to carve the magnificent cliffs and canyons seen today.
