Val Ferret is the name shared by two valleys separated by the Col Ferret, a pass on the border between Italy and Switzerland. The valleys lie southeast of Mont Blanc Massif. The Swiss valley drains northeast towards Orsières and on into the Rhône basin; whereas the Italian valley drains southwest towards Courmayeur and on into the Po basin.
The Pont d'Aël is a Roman aqueduct located in a village of the same name in the comune of Aymavilles in Aosta Valley, northern Italy. It was built in the year 3BC for irrigation purposes and supplying water for the newly founded colony of Augusta Praetoria, which is now known as Aosta. The water was directed through a neighbouring valley 66 m above the floor of the Aosta valley, through a sophisticated system. The aqueduct is 6 km long in total. In addition to its unusual position, the construction, which was originally thought to be a three-story structure, shows more unique features such as a control corridor below the water line, as well as explicit private funding. Today, the water channel of the aqueduct serves as a public walking trail.

The Theodul Glacier is a glacier of the Alps, located south of Zermatt in the canton of Valais. It lies on the Swiss side of the Pennine Alps, although its upper basin touches the Italian region of the Aosta Valley. The glacier descends from the west side of the Breithorn and splits into two diverging branches above Gandegg: the Upper Theodul Glacier, spilling on a high plateau near Trockener Steg, together with the Furgg Glacier, and the Lower Theodul Glacier, reaching a height of about 2,500 metres (8,202 ft) above the Gorner Glacier.

The Brenva Glacier is a valley glacier, located on the southern side of the Mont Blanc massif in the Alps. It is the second longest and eighth largest glacier in Italy, and descends down into Val Veny, close to Entrèves, near Courmayeur. Over the centuries it has experienced a number of major rock avalanches which have shaped the glacier and influenced its movement.
The Ivrea Morainic Amphitheatre is a moraine relief of glacial origin located in the Canavese region. Administratively, it encompasses the metropolitan city of Turin and, more marginally, the province of Biella and the province of Vercelli. It dates back to the Quaternary period and was created by the transport of sediment to the Po Valley that took place during the glaciations by the great glacier that ran through the Dora Baltea valley. With an area of more than 500 km2, it is one of the best-preserved geomorphological units of this type in the world. As an extension, it is surpassed in Italy only by the similar formation surrounding Lake Garda. The name amphitheater, usually given to these geomorphological structures, refers to their characteristic elliptical shape that is noticeable when it is shown as a plan on a map.
