Rock Heap is a geological term used to describe a PILE of rocks that have been moved and accumulated by natural forces such as wind, water, or ice. It is usually found in areas with high winds, such as deserts, or in areas with large amounts of snowfall, such as mountains. Rock Heaps are also known as rock piles, rock mounds, or rock drifts. They can be composed of any type of rock, from small pebbles to large boulders.
