Answer
While wind does play a role in shaping the landscape in arid regions, the bizarre shapes and hoodoos in Bryce Canyon National Park are primarily the result of water erosion, not wind. Bryce Canyon was formed by the erosional action of frost wedging and running water. During freezing and thawing cycles, water seeps into cracks in the limestone rocks. When the water freezes, it expands and creates pressure, causing the rocks to fracture and break apart. Over time, running water carves out the deep valleys and shapes the unique formations, including the hoodoos.
