Grus refers to rock fragments lying at the base of steep slopes. Which term describes this concept?

Explanation:
The main idea is naming the loose rock debris that collects at the base of steep slopes. Grus is the term for angular, coarse rock fragments that lie at the foot of cliffs, formed by physical weathering and breakage and then accumulating downward under gravity. This material is coarse and fragmental, not fine sand, and it sits at the base rather than along the slope, which distinguishes it from other loose slope materials.
