Provo's state (4)
I believe the answer is:
utah
'provo's state' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for utah that I've seen before include "Brigham Young state" , "Brigham Young's state" , "State of western US" , "US state settled by the Mormons" , "A hut for the Mormons, oddly" .)
