Question: What mountainous topography spans the French-Italian border?

Context paragraphs:
1st Airborne Task Force (Allied): The 1st Airborne Task Force was a short-lived Allied airborne unit that was active during World War II created for Operation "Dragoon"–the invasion of Southern France.  Formed in July 1944, under the command of Major General Robert T. Frederick, it took part in the "Dragoon" landings on 15 August 1944, securing the area north-west of the landing beaches, before moving towards the French-Italian border as part of the United States Seventh Army.  The unit was disbanded in November 1944.

Alps: The Alps ( ; French: "Alpes" ] ; German: "Alpen" ] ; Italian: "Alpi" ] ; Romansh: "Alps" ; Slovene: "Alpe" ] ) are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately 1,200 km across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland.  The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided.  Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn.  Mont Blanc spans the French–Italian border, and at 4810 m is the highest mountain in the Alps.  The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet).

Names of the Albanians and Albania: The Albanians (Albanian: "Shqiptarët" ) and their country Albania ("Shqipëria") have been identified by many ethnonyms.  The native endonym is Shqiptar.  The name "Albanians" (Byzantine Greek: "Albanoi/Arbanitai/Albanites"; Latin: "Albanenses/Arbanenses") was used in medieval Greek and Latin documents that gradually entered European languages from which other similar derivative names emerged.  Linguists believe that the "alb" part in the root word originates from an Indo-European term for a type of mountainous topography, meaning "hill, mountain", also present in "Alps".  Through the root word "alban" and its rhotacized equivalents "arban", "albar", and "arbar", the term in Albanian became rendered as "Arbëreshë" (Gheg Albanian: "Arbëneshë" ) for the people and "Arbëria" (Gheg Albanian: "Arbënia" ) for the country.

Ambin group: The Ambin group ("Groupe d'Ambin" in French, "Gruppo d'Ambin" in Italian) is a sub-range of the Cottian Alps located on the French-Italian border.

Vallée de la Clarée: The Vallée de la Clarée is a scenic valley in the French Alps near to Montgenèvre, Briançon and the French-Italian border.  The Clarée river runs through the valley.

Ventimiglia: Ventimiglia (Italian: "Ventimiglia" ] , Intemelio: "Ventemiglia", French: "Vintimille" ] ) is a city, "comune" (municipality) and bishopric in Liguria, northern Italy, in the province of Imperia.  It is located 130 km southwest of Genoa by rail, and 7 km from the French-Italian border, on the Gulf of Genoa, having a small harbour at the mouth of the Roia River, which divides the town into two parts.  Ventimiglia's urban area has a population of 55,000.

List of rivers of Japan: Rivers of Japan are characterized by their relatively short lengths and considerably steep gradients due to the narrow and mountainous topography of the country.  An often-cited quote is 'this is not a river, but a waterfall' by the Dutch engineer (o-yatoi gaikokujin) Johannis de Rijke who had visited the Jōganji River, Toyama Prefecture.  The Mogami, the Fuji and the Kuma are regarded as the three most rapid rivers of Japan.

Mont Cenis (train): The Mont Cenis was an international express train linking Lyon in France with Milan in Italy.  The train was named after the mountain range through which it crossed, inside the Fréjus Rail Tunnel (Mont Cenis tunnel in French) on the French-Italian border.

Via Lattea: The Via Lattea (Milky Way) is a winter sports area in the Italian and French Alps, straddling the French-Italian border at Claviere/Montgenèvre.  Located some 70 km (44 miles) west of Turin, it comprises the five Piedmontese resorts of Claviere (1760m), Sansicario (1700m), Sauze d'Oulx (1509m), Pragelato (1518m) and Sestriere (2035m) and additionally the French resort Montgenèvre (1850m).  Altogether there are 400 km (250 miles) of skiable pistes, 120 of them with artificial snow, and 88 lifts.  The lowest lift begins at 1350m in the service village of Cesana Torinese; the highest point is Mont Motta in the Sestriere ski area, at 2800m.  Claviere and Montgenèvre are connected at the lower limit of their ski area in the frontier pass, and at their highest point below the top of Mont Gimont but are not easily reachable from the other areas, relying on a slow lift system up from Cesana.  There are regular zero-fare bus services between the resorts.

Transport in New Zealand: Transport in New Zealand, with its mountainous topography and a relatively small population mostly located near its long coastline, has always faced many challenges.  Before Europeans arrived, Māori either walked or used watercraft on rivers or along the coasts.  Later on, European shipping and railways revolutionised the way of transporting goods and people, before being themselves overtaken by road and air, which are nowadays the dominant forms of transport.  However, bulk freight still continues to be transported by coastal shipping and by rail transport, and there are attempts to (re)introduce public transport as a major transport mode in the larger population centres.
