This method is illustrated in the above diagrams [fig. 213, 214] and will be more fully discussed below. A partial elevation of the coastal plain may occur and while a cuesta toi)()graphy is gradually carved out of the strata of this l)lain, a new coastal plain may be deposited with the older one for its shore and old land.
