Broad Sound North Entrance Channel

South Channel is a small channel in the United States located in Massachusetts Bay near Boston, Massachusetts. It runs alongside Devils Back and Aldridge Ledge from northeast of Ram Head to the western coast of Commissioners Ledge.

The Lovells Island Range Lights were range lights on Lovells Island in Boston Harbor, Massachusetts. They were built in 1903 to help vessels coming into what is now called "South Channel". As the North Channel was dredged deeper, the South Channel was less used and they were removed in 1939 to make room for the expansion of Fort Standish. The oil shed from the lights remains today.They were 400 feet (120 m) apart on a magnetic bearing of 228°, with a seven-foot walkway connecting them.

Magnifique was the lead ship of the 3-ship Magnifique class 74-gun ship of the line of the French Navy.

Fort Dawes was a World War II Coast Artillery fort located on Deer Island in Winthrop/Boston, Massachusetts. It was part of the Harbor Defenses of Boston.

The Deer Island Waste Water Treatment Plant (also known as Deer Island Sewage Treatment Plant) is located on Deer Island, one of the Boston Harbor Islands in Boston Harbor. The plant is operated by the Massachusetts Water Resources Authority (MWRA) and began partial operations in 1995. The facility was fully operational in 2000 with the completion of the outfall tunnel.Deer Island is the second largest sewage treatment plant in the United States. The plant is a key part of the program to protect Boston Harbor from pollution from sewer systems in eastern Massachusetts, mandated by a 1984 federal court ruling by Judge Paul G. Garrity, in a case brought under the Clean Water Act.From the 1880s until 1991, the northeastern side of the island was the location of the Deer Island Prison.

Fort Standish was a coastal fort completed in 1907 and located on Lovell's Island in Massachusetts. Named after Myles Standish, the fort would serve to host up to 7 batteries until it was disarmed and deactivated in 1947. It was also named Lovell's Island Military Reservation during the early part of its existence. It was part of the Coast (later Harbor) Defenses of Boston.Along with Fort Warren, Fort Andrews, Fort Banks, Fort Strong, and others, it was among the first modern defenses of Boston Harbor. The fort was de-activated in 1947 and in 1962 became part of the Boston Harbor Islands National Recreation Area.

Devils Back in Massachusetts, USA, is a very small and barren rock in the Atlantic Ocean located within the city limits of Boston. The rock is northeast of Aldridge Ledge, southwest of Commissioners Ledge, northwest of Half Tide Rocks, west of Green Island, and just east of the South Channel.

Lovells Island, or Lovell's Island, is a 62-acre (250,000 m2) island in the Boston Harbor Islands National Recreation Area, in Massachusetts. The island is across The Narrows from Georges Island and some 7 miles (11 km) offshore of downtown Boston. It is named after Captain William Lovell, who was an early settler of nearby Dorchester. The island is known as the site of several shipwrecks, including the 74-gun French warship Magnifique in 1782.In December 1786, a passenger boat carrying 13 people crashed off the shore of Lovells Island. Coming from Damariscotta, Maine, and destined for the Boston Harbor, the boat sank within swimming distance to the Harbor, and all aboard made it to shore. Without shelter or warmth and in the midst of a blizzard, 11 of the victims froze to death. One man, Theodore Kingsbury, made it through the night and was taken to the hospital in the morning where he was pronounced dead. Two of the victims aboard the ship, a Miss Sylvia Knapp and her fiancé (name unknown), were said to be found holding on to each other for warmth on top of a boulder, now dubbed "Lovers Rock". The Humane Society of the Commonwealth of Massachusetts constructed lifesaving huts in November 1787 around the harbor and the coast of Massachusetts, one on Lovells Island.Lovells Island has had a succession of owners. In 1767, the town of Charlestown deeded the island to Elisha Leavitt Jr. of Hingham, Massachusetts, an infamous Tory who also owned Grape Island, where Leavitt later invited British forces to help themselves to his hay until they were chased off by patriots. Leavitt's payment for Lovells Island was set aside to pay for the town's school.Lovells Island was used by Native Americans for fishing, gardening and trading. Later uses included harvesting the island's timber, as a fishing station, as a residence for the keepers of Boston Light, and as a rabbit run. Once the home of the Lovells Island Range Lights, the island was a buoy tending station in the early 20th century and was fortified before and during World War I, with remains of Fort Standish, active 1902-1946, still visible.Much of the vegetation on the islands results from an attempt in the 1930s by the Civilian Conservation Corps to reestablish a natural forest on the island, although this was largely cleared when the fort was reactivated during World War II. Left to recover after the war, the island's plant life now includes remnant patches of stands of poplar, pine and spruce, together with successional species such as staghorn sumac, black cherry, chokecherry, apple, and gray birch. Common shrubs include bayberry, beach plum, raspberry, Virginia rose and saltspray rose.Today, Lovells Island is a popular camping island, with picnic areas and walking trails through its dunes and woods, together with a non-supervised swimming beach. On weekends and summer weekdays, it is served by a shuttle boat to and from Georges Island, connecting there with ferries to Boston and Quincy.

Deer Island is a peninsula in Boston, Massachusetts. Since 1996, it has been part of the Boston Harbor Islands National Recreation Area. Although still an island by name, Deer Island has been connected to the mainland since the former Shirley Gut channel, which once separated the island from the town of Winthrop, was filled in by the 1938 New England hurricane. Today, Deer Island is the location of the Deer Island Waste Water Treatment Plant, whose 150-foot-tall (46 m) egg-like sludge digesters are major harbor landmarks. The island's permanent size is 185 acres (0.75 km2), plus an intertidal zone of a further 80 acres (320,000 m2). Two-thirds of the island's area is taken up with the wastewater plant, which treats sewage from 43 nearby cities and towns, and is the second-largest such plant in the United States. The remainder of the island is park land surrounding the treatment plant, and offers walking, jogging, sightseeing, picnicking, and fishing.

Deer Island Light is a lighthouse in Boston Harbor, Boston, Massachusetts. The actual light is 53 feet (16 m) above Mean High Water. Its alternating white and red light is visible for 9 nautical miles (17 km; 10 mi). The light is at the end of a reef that extends about 1,500 feet (460 m) south from Deer Island. The location first had a stone beacon in 1832. The first light, a sparkplug type light, was lit in 1890. It cost about $50,000. It included a three-story dwelling, a veranda with boat davits, and a circular parapet. The water supply was a cistern in the base of the structure. A spiral staircase ran from the cellar to the top floor. It had a fixed white light, which was changed to flashing red every thirty seconds and then to the present alternating red and white flashes. The old light gradually deteriorated and was replaced in 1982 by a white fiberglass tower. The white tower raised complaints because it blended in with the background and was hard to see, so the Coast Guard moved it to Great Point Light, Nantucket, as a temporary replacement when that tower was destroyed by a storm in March 1984. A brown fiberglass tower was installed immediately thereafter. While the Spark plug light was interesting, it was much more expensive to maintain than the fiberglass structure. Imported from England, the pole light was the first of its kind in the United States.Between October 2015 and May 2016, the brown tower was dismantled and the light was moved about 100 feet (30 m) south of its previous foundation structure. The new light uses LED technology and sits on a steel skeletal tower, atop four piles. Like other lights in Boston Harbor, the automatic fog signal has been replaced by a Mariner Radio Activated Sound Signal (MRASS) which can be activated by nearby mariners by tuning their marine VHF radio to channel 83A (157.17 5Mhz) and keying the transmitter five times consecutively.

Gallops Island, also known as Gallups Island, is an island in the Boston Harbor Islands National Recreation Area. It is situated between Georges Island and Long Island, and is just over 6 miles (9.7 km) from downtown Boston. The island has a permanent size of 23 acres (93,000 m2), plus an intertidal zone of a further 28 acres (110,000 m2), and is composed of one large drumlin, reaching an elevation of 79 feet (24 m) above sea level. The island has a rocky beach and offers long vistas from the top of its grassy bluffs. Gallops Island is closed until asbestos remediation is completed.The island is named after John Gallop, one of Boston Harbor's first pilots, who lived on the island. Since then the island has been occupied by a restaurant and inn and a quarantine station. During the Civil War the island was occupied by a military camp housing 3,000 Union soldiers, and during World War II it was occupied by a radio school and a school for bakers and cooks. During World War I, Gallops Island was used as an infirmary for thousands of American soldiers who contracted "Spanish influenza" and pneumonia. Many died every day, to be replaced by new arrivals. The island contains a collection of ornamental trees, shrubs and herbaceous plants that date back to its earlier uses, with additional trees being planted by the Civilian Conservation Corps in the 1930s. Photographs from the 1940s show that a tree lined street extended the length of the island. Although the buildings have been demolished, the pathways and foundations still exist and are lined with privet hedges and surrounded by fruit, shade and coniferous trees, including lilacs, mock-orange, snowberry, and forsythia. Also present are self-sown sumac, poplar, poison ivy, and bayberry. The vegetation has been badly damaged in recent years by the island's population of rabbits.Gallops Island was closed in 2000 due to the presence of asbestos-containing building debris from former military uses. The Massachusetts Department of Conservation and Recreation has determined that the island will be closed to the public until visitors can be welcomed back safely. As of August 2010, it was predicting a re-opening no earlier than 2015, presuming remediation funding could be obtained.

The Deer Island Prison (c. 1880–1991) in Suffolk County, Massachusetts was located on Deer Island in Boston Harbor. Once known as the Deer Island House of Industry and later, House of Correction, it held people convicted of drunkenness, illegal possession of drugs, disorderly conduct, larceny, and other crimes subject to relatively short-term sentencing. When it closed in 1991, some 1,500 inmates were being held at Deer Island.
