Loose fragments of rock on or at the foot of a mountain (5)

I believe the answer is:

scree

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

I've seen this clue in The Times.
