Abstract : Coastal reconnaissance during April and early May, 1970, in Oregon and northern California had the main objective of studyng marine erosional attack resulting from contrasts above and below the water table. Retreat of sea cliffs in the zone of aeration above ground water level is associated with the development of platforms of marine abrasion toward the top of the underlying zone of cementation, where rock is more durable. Pseudo-beach rock in sandy beaches consists of bedrock abraded along the zone of water table fluctuation. Some general comments on coastal landforms are included and some applications are indicated for users of small boats. A new terms, 'subswash zone,' is introduced. (Author)
