Strangely stark limestone landscape (5)

I believe the answer is:

karst

'limestone landscape' is the definition.
(type of geographical region)

'strangely stark' is the wordplay.
'strangely' indicates anagramming the letters.
'stark' is an anagram of 'KARST'.

(Other definitions for karst that I've seen before include "limestone area" , "Rough terrain" , "Limestone landscape" .)

I've seen this clue in The Times.
