Mountain or hill with two summits separated by a col

A **double summit**, **double peak**, **twin summit**, or **twin peak** is a [mountain](/source/Mountain) or [hill](/source/Hill) that has two [summits](/source/Summit), separated by a [col](/source/Col) or [saddle](/source/Saddle_(topography)).

A [syncline](/source/Syncline) forms this double summit in [Patagonia](/source/Patagonia)

One well-known double summit is [Austria](/source/Austria)'s highest mountain, the [Großglockner](/source/Gro%C3%9Fglockner), where the main summit of the Großglockner is separated from that of the [Kleinglockner](/source/Kleinglockner) by the Glocknerscharte col in the area of a geological fault.[1] Other double summits have resulted from [geological folding](/source/Folding_(geology)). For example, on Mont Withrow in [British Columbia](/source/British_Columbia), resistant sandstones form the limbs of the double summit, whilst the softer rock in the core of the fold was eroded.[2]

Triple peaks occur more rarely; one example is the [Rosengartenspitze](/source/Rosengartenspitze) in the [Dolomites](/source/Dolomites). The [Illimani](/source/Illimani) in [Bolivia](/source/Bolivia) is an example of a rare quadruple summit.
