scree

SKREE
A slope of small, loose, broken rock fragments accumulated at the base of a cliff or steep slope — finer than talus, typically ankle-deep, and miserable to ascend. Every step slides backward. Scree slopes are the debris fields of mountains slowly breaking apart.
Etymology
Old Norse skritha, a landslide, related to skriða, to slide.
