Oddly nude hill (4)

Ross

I believe the answer is:

dune

'hill' is the definition.
(I know that dune is a type of hill)

'oddly nude' is the wordplay.
'oddly' indicates anagramming the letters.
'nude' is an anagram of 'DUNE'.

(Other definitions for dune that I've seen before include "Coastal sand hill" , "Sandhill" , "Ridge of wind-blown sand" , "Mound of drifted sand" , "Nude in the sand" .)

I've seen this clue in The Mirror.
