'like some mounts of the' is the definition.
I can't tell whether this defines the answer.

'mid-atlantic end a trip' is the wordplay.
'mid' indicates the central letters.
'trip' is an anagram indicator.
The centre of 'atlantic' is 'an'.
'end'+'a'='enda'
'enda' anagrammed gives 'dean'.
'an'+'dean'='ANDEAN'

Can you help me to learn more?
