A high point in history (3)

I believe the answer is:

tor

'a high point' is the definition.
(a tor is a rocky hill)

'in history' is the wordplay.
'in' says the answer is hidden in the clue.
'TOR' can be found hidden inside 'history'.

(Other definitions for tor that I've seen before include "Pillar of rock" , "Rocky outcrop" , "eminence" , "Dartmoor peak" , "Rocky height, eg Mam" .)

I've seen this clue in The Globe and Mail.
