Quick Summary

A beach ridge is a geological formation composed of sand and gravel that is built up along a beach by wave action. These ridges can also be referred to as cheniers, which are typically made of sand-sized material resting on clay or mud.12

Beach ridges are evidence of fluctuations in sea level and can be correlated with similar geological evidence found globally. They are distinct from aseismic ridges, which are large, mountainous underwater structures formed by volcanism from a hot spot, and wave-cut platforms, which are rock ledges formed by wave abrasion at the base of sea cliffs.234
