Alpi Cusiane
# Alpi Cusiane

The Alpi Cusiane (or Prealpi Cusiane) are a sub-range of the Pennine Alps located in Piemonte (Italy).

## Etymology

Alpi Cusiane literally means Alps of Cusio; Cusio is the geographical and historical area surrounding Lake of Orta, nowadays part of the province of Verbano-Cusio-Ossola.

## Geography

Administratively the westernmost part of the range belongs to the province of Vercelli, the southern part to province of Novara and the eastern and central ones to province of Verbano-Cusio-Ossola.

### Borders

Borders of the Alpi Cusiane are (clockwise):

* Varallo Sesia, Mastallone creek, Tesslu pass, Strona creek, Gravellona Toce (north),
* Lago Maggiore (east),
* Po plain between Arona and Gattinara (south),
* Valsesia from Gattinara to Varallo Sesia (west).

### SOIUSA classification

According to SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain range is an Alpine supergroup classified in the following way:

* main part = Western Alps
* major sector = North-Western Alps
* section = Pennine Alps
* subsection = Southern Valsesia Alps
* supergroup =Alpi Cusiane
* code = I/B-9.IV-B

### Subdivision

The Alpi Cusiane are divided into two Alpine groups, none of them further subdivided in subgroups (in brackets is reported their SOIUSA code):

* costiera Capio-Massa del Turlo ( I/B-9.IV-B.1)
* massiccio del Mottarone ( I/B-9.IV-B.2)

These two groups are connected by a low saddle not faraway from Gozzano.

## Geology

From the geological point of view the Alpi Cusiane are considered part of the Prealpine zone, divided from the crystalline zone of the Alps by the Insubric line. This important geologic fault forms the border between the Adriatic plate and the European plate. Hills and mountains located south-east of the line, like the Alpi Cusiane, can be considered part of southern Apulian foreland.
