Ascended a small hill to the North (5)
I believe the answer is:
risen
'ascended' is the definition.
(rising is a kind of ascending)
'a small hill to the north' is the wordplay.
'a small hill' becomes 'rise' (I've seen this in another clue).
'to the north' becomes 'N' (abbreviation).
'rise'+'n'='RISEN'
(Other definitions for risen that I've seen before include "Increased" , "Resin (anag.)" , "Grown up" , "Above the horizon" , "Ascended - restored from death" .)
