===Mount Sinai Harbor===
[[File:Mountsinaiharbor.JPG|thumb|right|Boats at Mount Sinai Harbor]]
The northern part of Mount Sinai Harbor borders an active recreation area that is located on a 2-mile long peninsula.  This includes [[Cedar Beach (Brookhaven, New York)|Cedar Beach]], one of the most popular North Shore beaches during the summer months. A marine sanctuary and nature preserve connects the various sections of Cedar Beach with scenic walking trails and serves to protect the remaining sand dunes.  Commonly owned lands set aside in 1664 are being used for public recreation or have been rented for private use by a fishing station, yacht club and boatyard. A number of commercial fishermen work out of the harbor and fish in Long Island Sound.  The peninsula, which is most directly accessible from the neighboring community of [[Miller Place, New York|Miller Place]], contains a number of historical vacation houses on both sides of the boundary line.  The majority of these houses have since been converted to full-year use.

The southern part of it is a more serene location.  Clamming is a popular activity during low tide, as is fishing at high tide.  Throughout its history, Mount Sinai Harbor has been utilized for the catching of [[shellfish]], the fishing of [[lutjanidae|snapper]] and [[flounder]], the hunting of waterfowl, sand milling, and the harvesting of [[Spartina patens|salt hay]].  Satterly Landing, a small park that once housed a boathouse, provides views across the harbor.

The original mouth of the harbor was on the east side. Winds and tides continually narrowed its opening. Local residents toiled at widening the mouth. In the mid 19th century a new mouth was dredged on the west side of the harbor. Tides continue to dump sand, narrowing the mouth of the harbor. It still must be dredged to keep it open to allow for the boats moored in the harbor to reach the Sound. Three major civic battles were waged in the 20th century when various plans to dredge the harbor were proposed and pursued by the Town of Brookhaven. Two dredging projects were approved, and the present channels and deep basin south of Cedar Beach are the result of that action. A united civic action finally got the dredges out of the harbor in the late 1960s.{{US Census population
