Double summit

A double summit, double peak, twin summit or twin peak refers to a mountain or hill that has two summits, separated by a col or saddle.

One well known double summit is Austria’s highest mountain, the Großglockner, where the main summit of the Großglockner is separated from that of the Kleinglockner by the Glocknerscharte col in the area of a geological fault. Other double summits have resulted from geological folding. For example, on Mont Withrow in British Columbia resistant sandstones form the limbs of the double summit, whilst the softer rock in the core of the fold was eroded.

Triple peaks occur more rarely - one example is the Rosengartenspitze in the Dolomites. The Illimani in Bolivia is an example of a quadruple summit.

Double Peak (San Diego County, California)

Double Peak is located south of San Marcos, California. The elevation at the is summit is 1,646 ft (502 m), and approximately 1,000 feet (305 m) above the north foot of the mountain. Most trails leading to the summit of Double Peak are classified as "moderately strenuous."

Double Peak is a popular hiking and biking area due to its many trails and convenient access points. On the north side, the mountain can be accessed by hikers and bikers through Discovery Lake Park, but this trailhead is closed to motorized vehicles. On the south side, the mountain can be accessed by vehicles through Double Peak Drive, extending from the neighborhood of San Elijo Hills. Both the North and the South access trails offer wide, partially paved surfaces. There is also a less-accessible rock and dirt trail which allows summiting the mountain from the East side. The Eastern trail has a steep incline, with rugged, staircase-like rock extrusions and at some points, loosely packed shale. The Eastern trail can only be accessed by following other trails along either the north or south face of the mountain, around to the eastern face of the mountain.
