Line parent A peak's line parent is the closest higher peak on the highest ridge leading away from the peak's "key col". A col is the lowest point on the ridge between two summits and is synonymous with pass, gap, saddle and notch. A peak's "key col" is the lowest point on the ridge which connects the peak and a higher peak.

Usually, a line parent must meet some prominence criteria, which might vary depending on the author and the location of the peak.〔(【引用サイトリンク】publisher=Bivouac.com )〕〔(【引用サイトリンク】publisher=LoJ.com )〕〔(【引用サイトリンク】title=Peakbagger.com Help and Glossary: Line Parent )〕 There are at least two other kinds of peak parentage.
