Stuff in deep ravine (5)
I believe the answer is:
gorge
I believe this is a double definition.
'stuff' is the first definition.
('gorge' can be a synonym of 'stuff')
'deep ravine' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for gorge that I've seen before include "Eat greedily" , "Steep narrow ravine" , "Long belted tunic" , "Steep narrow valley" , "Make this rise to sicken or disgust" .)
