To south, near Neptune Beach, sediments disappear beneath beach level but reappear several miles to southeast along sea cliffs of Lummi Peninsula. Overlies Cherry Point silt at type section[!] of the Cherry Point. Shown on sketch map of northern Puget Lowland as "Mt. View formation." Age is considered late Pleistocene.
