Unruly piles can be described as HEAPS, which is a five-letter word. HEAPS are large accumulations of objects that are often disorderly and unorganized. They can be made up of anything from dirt and rocks to garbage and other debris. Unruly piles are usually created by natural forces such as wind or water, but they can also be created by humans. Unruly piles can be dangerous and can cause damage to property or the environment if not managed properly.
