A pile of rocks at the base of a steep slope is called?

Explanation:
A pile of rock debris at the base of a steep slope is talus. It forms when pieces break off from higher on the slope and fall or slide down due to gravity, accumulating as a loose, cone- or apron-shaped slope at the bottom. The material is typically poorly sorted rubble, and its steep side is limited by the angle of repose of the debris. Eskers are winding ridges formed by sediment deposited by subglacial streams, till is unsorted material dropped directly by a retreating glacier, and moraines are accumulations of glacial debris carried and deposited at the edges or terminus of a glacier.
