 The issue of the attachment or not of Modane in the Maurienne Valley or Haute-Maurienne differs depending on the disciplines of economics, geography or geology.For economists, Modane is attached to Haute Maurienne, arguing that the city has a very strong influence on the villages of Haute Maurienne, through economic and administrative infrastructure such as shopping centres, schools or the railway station for example.However, for the great majority of analysts, Modane is a commune attached to the middle part of this valley, both by the relief (encompassing the whole canton is a dug coal-bearing furrow which extends to Saint-Michel-de-Maurienne), and by the industrial history of this sector.
