The question is incomplete. As the question is in the singular it implies that it is about a quote not about 2 mountains. Therefore assume the quote is 'The 2 most dangerous mountains in New York'.
Again I suggest this is incomplete and should be re read in two parts:
'The 2 most dangerous mountains' and 'in new York'
Google seems to provide the answer. Add a bit, delete a bit and you have:
