From Baltimore go north for this state (6)
I believe the answer is:
oregon
'this state' is the definition.
(I know that Oregon is a American state)
'from baltimore go north' is the wordplay.
'from' says the answer is hidden in the clue.
'OREGON' is hidden in the letters of 'baltimore go north'.
'for' is the link.
(Other definitions for oregon that I've seen before include "Salem's state" , "US west-coast state" , "US state, capital Salem" , "No gore seen in this American state" , "West coast US state" .)
