Find it loose on the mountainside (5)

I believe the answer is:

scree

(Other definitions for scree that I've seen before include "Sloping mass of loose rock at the base of a cliff" , "Safeguard" , "Mass of loose rocks at the base of a cliff" , "Loose stones on mountain slope" , "Loose stones around a mountain" .)

I've seen this clue in The Guardian.
