The upper valleys of the Canton Ticino have been the theatre of important descriptions and interpretations about the morphogenesis of Alpine glacial valleys since the mid-nineteenth century. William Morris Davis, for example, visited this region at the end of the nineteenth century. Numerous sites host remarkable associations of glacial, periglacial and/or fluvial landformsFluvial landscape. We present here, as examples, (a) the GreinaGreina plateau, a symbol in the preservation of natural heritage in Switzerland, which is considered a fragment of arctic tundra in the Alps; (b) the rock glaciersRock glacier of the southern side of Adula, the most emblematic periglacial site in the Southern Swiss Alps; and (c) the Bolle di MagadinoBolle di Magadino, corresponding to the youngest part of the Ticino RiverTicino River delta in Lake Maggiore. The ideas and landscape evolution related to the origin of the southern Alpine valleys are finally discussed.
