Raised strip of land (5)
I believe the answer is:
ridge
'raised strip of land' is the definition.
(ridge can mean a strip of land)
This is all the clue.
(Other definitions for ridge that I've seen before include "Elongated area of high pressure" , "Top of roof or incline" , "Part of mountain" , "Long raised band" , "Narrow raised strip as between hills" .)
