Turkey's highest peak (6)
I believe the answer is:
ararat
'turkey's highest peak' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ararat that I've seen before include "historic landing site" , "original dry dock" , "Turkish Mount said to contain Noah's Ark" , "Ark's supposed resting place" , "Biblical mount" .)
