Talus is a slope formed by the accumulation of broken rock fragments at the base of a cliff, produced by physical weathering processes such as freeze-thaw cycles. Talus slopes are significant in geomorphology for understanding the processes of mechanical weathering, mass wasting, and the development of mountainous landscapes.
