While it carved these beautiful rock and land formations visitors flock to see, these processes are also responsible for the fall of Wall Arch in 2008. Flooding also created gullies in some fields and may have deposited sand, silt and other debris. In theory, if there were no underlying rock to stop erosion process, gullies could be as wide and deep as the water power flowing through them could cut and shape them to be. Erosion is the gradual destruction or breaking down of a material by an agent, like water, wind or harsh chemicals. Rills can generally be easily removed by tilling the soil.
