Over time, the wind erodes the sandstone into different shapes and sizes. It does this by blowing the sand around and off the stones.

In the same way as the sand dunes, the rock underwater was smoothed by the passing of the water. The rock she found underground, however, has rough edges because of the rocks breaking off and the cooling of lava.
