Sitka's state (6)
I believe the answer is:
alaska
'sitka's state' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for alaska that I've seen before include "Most northerly state of America" , "State of north-west US" , "Anchorage location" , "Most northerly state of USA" , "Forty-ninth US state" .)
