Hunter from Maryland or Minnesota, travelling north (6)
I believe the answer is:
nimrod
'hunter' is the definition.
(I know that Nimrod is a hunter)
'from maryland or minnesota travelling north' is the wordplay.
'from' indicates a hidden word.
'travelling north' says the letters should be written in reverse (in a down clue, letters go up).
'dormin' can be found hidden inside 'maryland or minnesota'.
'dormin' reversed gives 'NIMROD'.
(Other definitions for nimrod that I've seen before include "Might hunter of Genesis" , "Old hunter" , "'Mighty Biblical ruler, builder of the Tower of Babel (6)'" , "Mighty Biblical ruler, said to have built Tower of Babel" , "Dim Ron was a bad Biblical hunter" .)
