Col
lowest point on a mountain ridge between two neighboring peaks in one sense or the same as a mountain saddle in the other sense
A col in geomorphology is the lowest point on a mountain ridge between two peaks. It may also be called a gap or pass. Particularly rugged and forbidding cols in the terrain are usually referred to as notches. They are generally unsuitable as mountain passes, but are occasionally crossed by mule tracks or climbers' routes. Derived from the French col ('collar, neck') from Latin collum, 'neck', the term tends to be associated more with mountain than hill ranges. The distinction with other names for breaks in mountain ridges such as saddle, wind gap or notch is not sharply defined and may vary from place to place. Many double summits are separated by prominent cols.
The height of a summit above its highest col (called the key col) is effectively a measure of a mountain's topographic prominence.
Cols lie on the line of the watershed between two mountains, often on a prominent ridge or arête. For example, the highest col in Austria, the Obere Glocknerscharte ("Upper Glockner Col", 3,766 m (AA)) lies between the Kleinglockner (3,783 m above sea level (AA)) and Grossglockner (3,798 m above sea level (AA)) mountains, giving the Kleinglockner a minimum prominence of 17 metres.
The public source identifies “Col” as lowest point on a mountain ridge between two neighboring peaks in one sense or the same as a mountain saddle in the other sense. This brief keeps that definition visible, then builds a research path around lowest, point and mountain.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Col”, the useful work is to connect “lowest point on a mountain ridge between two neighboring peaks in one sense or the same as a mountain saddle in the other sense” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q2231510. None of the 0 selected statements returned an explicit reference.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
