'scottish mountain' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'accountant's climbing on amazing mornirg' is the wordplay.
'accountant' becomes 'ac'.
'climbing' is a reversal indicator (in a down clue, letters climb up).
'on' is a charade indicator (letters next to each other).
'amazing' is an anagram indicator.
'ac' backwards is 'ca'.
'mornirg' is an anagram of 'irngorm'.
'ca'+'irngorm'='CAIRN GORM'
