Hello, During my skitour on the Dufourspitze a discussion arose about the Monte Rosa Massif and it being the largest (volume wise) in the Alps. So the question is what is considered as the limit of the Monte Rosa Massif? Same goes for the Mont Blanc massif. I've always spoken about, and have seen it written that, the Massif extends from the Trient group in the north to the high peaks around les Contamines and the Col de le Seigne which of course would make it much bigger than what is indicated on the Topo Map for the Monte Rosa.
Thanks and cheers
