Hydraulic action and abrasion erodes a weakness in the rock at the base of the cliff to form a wave-cut notch The continual undercutting increases the size of the wave cut notch which increases the stress and tension in the cliff. Sediments were collected (Lepper, 2020) for aging using Optically Stimulated Luminescence in several locations to refine information gaps on the south and east sides of the bog and around the pine barrens.
