This might be a double definition.

'mountains' is the first definition.

'in' is the link.

(Other definitions for atlas that I've seen before include "Chart book" , "I carry a huge weight" , "Map collection" , "travel book" , "N. African mountains; a Titan" .)

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