Victor Frankenstein meets his creation, the monster, at the summit of the Swiss mountain. There, in the seas and crevices of snow and ice he confronts his creation--the maker meets his offspring. The meeting takes place in the alps because Shelley was trying to impart a sublime mood to the encounter. This is tied into most of the themes we see in the novel such as isolation, alienation, responsibility, ethical choice, etc. Please explore the Enotes theme page, link suggested below.
