609 – Beaches, bouldery

This very deep, nearly level map unit is adjacent to glacial till landforms of Cape Cod Bay, Buzzards Bay and Boston Harbor. The beaches bouldery map unit is not vegetated and generally consists of larger boulders and stones with layers of gravelly and cobbly sand. The boulder and stone size rock fragments cover over 60 percent of the map unit. Some areas have a gravelly or cobbly surface. The area nearest the water is gently sloping and is inundated twice daily by tides. The entire beach is generally flooded by spring tides and storm events.

Included with this map unit in mapping are small areas of Hooksan, Ipswich, Pawcatuck, and Matunuck soils. Also included are areas of unvegetated dune sand.

Vegetation does not grow in these areas because of inundation by salt water and frequent reworking of the sand by wave action. Beaches, bouldery are unsuited for most uses. These areas are not usually used for recreational uses due to the large rock fragments.
