Cape Cod is a peninsula extending into the Atlantic Ocean from the southeastern corner of Massachusetts, in the northeastern United States. Its historic, maritime character and ample beaches attract heavy tourism during the summer months. The name Cape Cod, coined in 1602 by Bartholomew Gosnold, is the ninth-oldest English place-name in the U.S.
As defined by the Cape Cod Commission's enabling legislation, Cape Cod is coextensive with Barnstable County, Massachusetts. It extends from Provincetown in the northeast to Woods Hole in the southwest, and is bordered by Plymouth to the northwest. The Cape is divided into fifteen towns, several of which are in turn made up of multiple named villages. Cape Cod forms the southern boundary of the Gulf of Maine, which extends north-eastward to Nova Scotia.
Since 1914, most of Cape Cod has been separated from the mainland by the Cape Cod Canal. The canal cuts 7 miles (11 km) roughly across the base of the peninsula, though small portions of the Cape Cod towns of Bourne and Sandwich lie on the mainland side of the canal. Two highway bridges cross the Cape Cod Canal: the Sagamore Bridge and the Bourne Bridge. In addition, the Cape Cod Canal Railroad Bridge carries railway freight and provides limited passenger service onto the Cape.
Region of Cape Cod and the Islands
Like Cape Cod itself, the islands south of the Cape have evolved from whaling and trading areas to become resort destinations, attracting wealthy families, celebrities, and tourists. These include the large nearby islands of Nantucket and Martha's Vineyard. Both islands are also famous summer tourist destinations, commonly accessed by ferry from several locations on the Cape. The phrases Cape Cod and the Islands and the Cape and Islands are often used to describe the whole region of Barnstable County, Dukes County (including Martha's Vineyard and the smaller Elizabeth Islands), and Nantucket County.
Several small islands right off Cape Cod, including Monomoy Island, Monomoscoy Island, Popponesset Island, and Seconsett Island, are also in Barnstable County.
The Forbes family-owned Naushon Island was first purchased by John Murray Forbes. Naushon is one of the Elizabeth Islands, many of which are privately owned. One of the publicly accessible Elizabeths is the southernmost island in the chain, Cuttyhunk Island, with a year-round population of 52 people. Several prominent families have established compounds or estates on the larger islands, making these islands some of the wealthiest resorts in the Northeast, yet they retain much of the early merchant trading and whaling culture.
Cape Cod in particular is a popular retirement area; 31.8% of the population of Barnstable County is 65 years old or older., and the average age of residents is the highest of any area in New England. Cape Cod is majority Democrat, but by a smaller margin than the rest of Massachusetts.
The bulk of the land in the area is glacial terminal moraine and represents the southernmost extent of glacial coverage in southeast New England; similar glacial formations make up Long Island in New York and Block Island in Rhode Island.
Geography and political divisions
Physical geography and boundaries
The name "Cape Cod", as it was first used in 1602, applied only to the very tip of the peninsula. It remained that way for 125 years until the "Precinct of Cape Cod" was incorporated as the Town of Provincetown. No longer in "official" use over the ensuing decades, the name came to mean all of the land east of the Manomet and Scusset rivers – essentially along the line that became the Cape Cod Canal. The creation of the canal separated the majority of the peninsula from the mainland. Many state and federal agencies, including the Cape Cod Commission and the Federal Emergency Management Agency (FEMA), treat the Cape as an island with regard to disaster preparedness, groundwater management, and other infrastructure factors. Cape Codders tend to refer to the land on the mainland side of the canal as "off-Cape", though the legal delineation of Cape Cod, coincident to the boundaries of Barnstable County, includes portions of the towns of Bourne and Sandwich that are located north of the canal.
Cape Cod Bay lies in between Cape Cod and the mainland – bounded on the north by a line between Provincetown and Marshfield. North of Cape Cod Bay (and Provincetown) is Massachusetts Bay, which contains the Stellwagen Bank National Marine Sanctuary, located 5 miles (8 km) north of Provincetown. Cape Cod Bay and Massachusetts Bay are both part of the Gulf of Maine, which includes the waters between the Cape and Nova Scotia. The Atlantic Ocean is to the east of Cape Cod, and to the southwest of the Cape is Buzzards Bay. The Cape Cod Canal, completed in 1916, connects Buzzards Bay to Cape Cod Bay; its creation shortened the trade route between New York and Boston by 62 miles (100 km).
Cape Cod extends 65 miles (105 km) into the Atlantic Ocean, with a breadth of between 1–20 miles (1.6–32.2 km), and covers more than 400 miles (640 km) of shoreline. Its elevation ranges from 306 feet (93 m) at its highest point, at the top of Pine Hill, in the Bourne portion of Joint Base Cape Cod, down to sea level.
Cape Cod and the Islands form part of a continuous archipelagic region consisting of a chain of islands running from Long Island to the tip of the Cape. This region is historically and collectively known by naturalists as the Outer Lands.
Towns and villages
Cape Cod incorporates all of Barnstable County, which comprises 15 towns: Bourne, Sandwich, Falmouth, Mashpee, Barnstable, Yarmouth, Harwich, Dennis, Brewster, Chatham, Orleans, Eastham, Wellfleet, Truro, and Provincetown. Each of these towns includes a number of villages; see Barnstable County for a complete list.
Barnstable, the most populated municipality on Cape Cod, is the only one to have adopted a city form of government, whose legislative body is an elected 13-member council. However, like other smaller Massachusetts cities, Barnstable retained its "Town of Barnstable" moniker. All of the other towns elect a 5-member Board of Selectmen as the executive policy-setting board and utilize Town Meetings as their legislative body.
Cape Cod and the Islands
To the south of Cape Cod lie Nantucket Sound; Nantucket and Martha's Vineyard, both large islands; and the mostly privately owned Elizabeth Islands.
Sections
For most of the 18th, 19th, and 20th centuries, Cape Cod was considered to consist of three sections (see map):
The Upper Cape is the part of Cape Cod closest to the mainland, comprising the towns of Bourne, Sandwich, Falmouth, and Mashpee. Falmouth is the home of the famous Woods Hole Oceanographic Institution and Marine Biological Laboratory as well as several other research organizations, and is also the most-used ferry connection to Martha's Vineyard. Falmouth is composed of several separate villages, including East Falmouth, Falmouth Village, Hatchville, North Falmouth, Teaticket, Waquoit, West Falmouth, and Woods Hole, as well as several smaller hamlets that are incorporated into their larger neighbors (e.g., Davisville, Hatchville, Falmouth Heights, Quissett, Sippewissett, and others). Bourne is home to the Massachusetts Maritime Academy, in the village of Buzzards Bay, along the canal, Joint Base Cape Cod, Aptucxet Trading Post, the annual Bourne Scallop Festival in September, and, until 1884, was part of Sandwich. Sandwich, the oldest town on Cape Cod, founded in 1637, is home to the Dexter Grist Mill, the historic Hoxie House, Heritage Museums and Gardens, and the Sandwich Glass Museum. Mashpee is the home of the Mashpee Wampanoag Tribe of Native Americans.
The Mid-Cape area includes the towns of Barnstable, Yarmouth and Dennis. The area features many beaches, including warm-water beaches along Nantucket Sound, e.g., Kalmus Beach in Hyannis, which gets its name from one of the inventors of Technicolor, Herbert Kalmus. This popular windsurfing destination was bequeathed to the town of Barnstable by Dr. Kalmus on condition that it not be developed, possibly one of the first instances of open-space preservation in the US. The Mid-Cape is also the commercial and industrial center of the region. There are seven villages in Barnstable, including Barnstable Village, Centerville, Cotuit, Hyannis, Marstons Mills, Osterville, and West Barnstable, as well as several smaller hamlets that are incorporated into their larger neighbors (e.g., Craigville, Cummaquid, Hyannis Port, Santuit, Wianno, and others). The villages of Yarmouth are South Yarmouth, West Yarmouth and Yarmouth Port. There are five villages in Dennis, including North Dennis, East Dennis, West Dennis, Dennis Port, and South Dennis.
The Lower Cape & Outer Cape traditionally includes all of the rest of the Cape, or the towns of Harwich, Brewster, Chatham, Orleans, Eastham, Wellfleet, Truro, and Provincetown. In the present day, the four outermost towns (Provincetown, Truro, Wellfleet, and Eastham) are more commonly and collectively known as the Outer Cape. This area is home to the Cape Cod National Seashore, a national park that encompasses much of the Lower Cape, including the entire east-facing coast from Orleans to Provincetown. The Lower Cape is home to popular beaches such as Nauset Light Beach and Coast Guard Beach in Eastham, Race Point Beach in Provincetown, Ballston Beach in Truro, and Skaket Beach in Orleans. This area is less populated than the rest of Cape Cod, though Provincetown can have a crowded, city-like atmosphere during the summer season. Provincetown has become a major gay & lesbian resort destination – the town is regarded as one of the largest LGBT resort communities in the United States. Provincetown is also renowned for its historic fishing fleets and Stellwagen Bank, a popular fishing ground and whale watching destination, is located a few miles north of Race Point.
Geology
The bulk of the land on Cape Cod consists of glacial landforms, formed by terminal moraine and outwash plains. This represents the southernmost extent of glacial coverage in southeast New England; similar glacial formations make up Long Island in New York and Block Island in Rhode Island. Together, these formations are known as the Outer Lands, or more obscurely as the "Isles of Stirling". Geologically speaking, Cape Cod is quite young, having been laid down some 16,000 to 20,000 years ago.
Most of Cape Cod's geological history involves the advance and retreat of the Laurentide Ice Sheet in the late Pleistocene geological era and the subsequent changes in sea level. Using radiocarbon dating techniques, researchers have determined that around 23,000 years ago, the ice sheet reached its maximum southward advance over North America, and then started to retreat. Many kettle ponds – clear, cold lakes – were formed and remain on Cape Cod as a result of the receding glacier. By about 18,000 years ago, the ice sheet had retreated past Cape Cod. By roughly 15,000 years ago, it had retreated past southern New England. With so much of Earth's water locked up in massive ice sheets, the sea level was lower. Truro's bayside beaches used to be a petrified forest before it became a beach.
As the ice began to melt, the sea began to rise. Initially, sea level rose quickly, about 15 metres (49 ft) per 1,000 years, but then the rate declined. On Cape Cod, sea level rose roughly 3 metres (9.8 ft) per millennium between 6,000 and 2,000 years ago. After that, it continued to rise at about 1 metre (3.3 ft) per millennium. By 6,000 years ago, the sea level was high enough to start eroding the glacial deposits that the vanished continental ice sheet had left on Cape Cod. The water transported the eroded deposits north and south along the outer Cape's shoreline through a process known as longshore drift. Those reworked sediments that moved north went to the tip of Cape Cod. The entire town of Provincetown, at the extreme tip of the Cape, is a spit consisting largely of deposited marine sediment that was eroded and transported from farther south along the shore. Those sediments that instead moved south created the islands and shoals of Monomoy. So while other parts of the Cape have dwindled from the action of the waves, these parts of the Cape have grown through the deposition of sediment in just the last 6,000 years.
This process continues today. Due to their exposure to the open ocean, the Cape and islands are subject to considerable coastal erosion. Due to erosion, the Cape will be completely submerged by the sea within several thousand years. This erosion causes the washout of beaches and the destruction of the barrier islands; for example, the ocean broke through the barrier island at Chatham during Hurricane Bob in 1991, allowing waves and storm surge to hit the coast with no obstruction. Consequently, the sediment and sand from the beaches are being washed away and deposited elsewhere. While this destroys land in some places, it creates land elsewhere, most noticeably in marshes where sediment is deposited by flowing water.
Cape Cod's aquifer consists of six hydrologically independent lenses from which all the towns on the Cape obtain drinking water (except Falmouth, which, in 2015, drew 43.5% of its water from Long Pond). Contamination with industrial chemicals and pharmaceutical drugs from septic systems is a concern. In 2023, the state began a nitrogen pollution regulation scheme for Cape Cod and the Islands to address overgrowth of algae, cyanobacteria, and plants.
Climate
Under the Köppen climate classification, the Cape Cod area has an oceanic climate. Locally, the Cape has a more moderate climate than inland locations in eastern New England. On occasion, it takes the brunt of extreme weather systems such as the Blizzard of 2005 and Hurricane Bob. Because of the influence of the Atlantic Ocean on three sides, temperatures are typically a few degrees lower in the summer and often several degrees higher in the winter than the adjacent mainland. Two ocean currents (the Gulf Stream, a warm ocean current from the south, and the Labrador Current, a cold ocean current from the north), meander and interact with each other. As a result, the ocean temperatures on the eastern shore of Cape Cod rarely get above 60 °F (16 °C), while along the southern coast (Nantucket Sound), water temperatures can sometimes reach 70 °F (21 °C) or higher.
The water surrounding Cape Cod moderates winter temperatures nearly enough to extend the humid subtropical climate zone to what could be its northernmost limit in eastern North America, as the peninsula is split between USDA hardiness zones 7a (Upper and Mid Cape) and 7b (Lower and Outer Cape). Consequently, many subtropical indicator plant species typically found in more southerly latitudes are grown there, including Camellias, Ilex opaca, Magnolia grandiflora and Albizia julibrissin. However, Cape Cod falls below the 72 °F (22 °C) threshold, as the warmest month, July, averages around 68.25 °F (20.14 °C).
Cape Cod's climate is also known for a delayed spring season due to the sea remaining cold from the winter; by the same token, the summer heat retained in the sea moderates fall temperatures in comparison to the adjacent inland area. The highest temperature yet recorded on the peninsula was 104 °F (40 °C) in Provincetown, the lowest temperature recorded was −12 °F (−24 °C) in Barnstable.
Precipitation on Cape Cod and the islands of Martha's Vineyard and Nantucket is the lowest in the southern New England region, averaging slightly less than 40 inches (100 cm) a year (most parts of New England average 42 to 46 inches (110 to 120 cm)). This is due to the maritime influence inhibiting summertime thunderstorm development and maintenance. The region does not experience a greater number of sunny days, however, as the number of cloudy days is the same as inland locales, in addition to increased fog. On average, roughly 27 inches (69 cm) of snow, which is about 17 inches (43 cm) less than Boston, falls in an average winter.
Once every five or six years, a tropical storm, accompanied by very high and potentially damaging winds and heavy rain, will strike the region. About once every 11 or 12 years a hurricane brings damaging winds and storm surges to the region. Several Category 3 storms have struck Cape Cod since record-keeping began, such as a hurricane in 1869, the 1938 New England hurricane, and Hurricane Carol in 1954. Strong Category 2 storms, such as the 1869 Saxby Gale, Hurricane Edna in 1954, and Hurricane Bob in 1991, also caused considerable damage. Notable Category 1 storms include the 1944 Great Atlantic hurricane and Hurricane Donna in 1960. Other notable storms include the Gale of 1815, which would likely have been rated a strong hurricane on the Saffir-Simpson scale, and the so-called "Perfect Storm" of October 31, 1991. The February 2013 nor'easter produced winds in excess of 80 miles per hour (130 km/h) and dropped over 24 inches (61 cm) of snow on some parts of Cape Cod. The storm knocked out power to tens of thousands of Cape Cod residents, some for up to two weeks.
Wildfires
Cape Cod has a long history of wildfire activity. Stephen Pyne, in his fire survey of the northeastern United States, describes the Cape as "among the most flammable landscapes in America" owing to its pitch pine-dominated vegetation, referring to it as "Cape Flame." Indigenous peoples historically used fire to attract game, promote desirable plants, and clear travel routes, and early European settlers continued fire management for agricultural purposes.
The most notable recorded event was the 1887 Cape Cod wildfires, in which at least six distinct fires erupted on May 11, 1887, under abnormally warm and dry conditions. Over 75,000 acres burned across three days, with the fires threatening the towns of Bourne and Falmouth. Subsequent large fires occurred in 1938, 1957, and 1963. A decline in fire activity during the twentieth century, associated with active fire suppression policies, led to denser, more flammable forests. Prescribed fire has been increasingly used in recent decades to manage fuel loads and support disturbance-dependent ecosystems.
History
Wampanoag peoples
Cape Cod has been the home of the indigenous Wampanoag for centuries prior to European colonization. They lived from the sea and were accomplished farmers. They understood the principles of sustainable forest management, and were known to light controlled fires to keep the underbrush in check. They helped the Pilgrims, who arrived in the fall of 1620, survive at their new Plymouth Colony.
The Wampanoag gradually lost their lands during the period of European incursion through land cessions and violent conflict with white settlers. The 1993 documentary Natives of the Narrowland shows the history of the Wampanoag people through Cape Cod archaeological sites.
In 1974, the Mashpee Wampanoag Tribal Council was formed to articulate the concerns of those with Native American ancestry. They petitioned the federal government in 1975 and again in 1990 for official recognition of the Mashpee Wampanoag as a tribe. In May 2007, the Wampanoag tribe was federally recognized.
European exploration
Cape Cod was a landmark for early explorers. It may have been the "Promontory of Vinland" mentioned by the Norse voyagers (985–1025), although this is disputed. The Manomet River area (taken up by the western end of the Cape Cod Canal in the early 20th century) is claimed by some to have been visited by Leif Eiriksson, and a stone wall discovered in Provincetown in 1805 is also claimed to have been built by his younger brother Thorvald Eiriksson around AD 1007, when the keel of his ship was repaired in the harbor, according to Norse sagas. He was killed later in the same journey and is said to have been returned to this spot for burial. However, there is no tangible support of the presence of Norse voyagers on Cape Cod, and the view is not generally accepted by archaeologists or historians.
Giovanni da Verrazzano approached it from the south in 1524. He named Martha's Vineyard Claudia, after Claude of France, the wife of Francis I of France. In 1525, Portuguese explorer Estêvão Gomes called it Cabo de las Arenas while sailing under the Spanish crown.
In 1602, Bartholomew Gosnold named the tip Cape Cod, the surviving term and the ninth oldest English place-name in the U.S. Samuel de Champlain charted its sand-silted harbors in 1606, and Henry Hudson landed there in 1609. Captain John Smith noted it on his map of 1614, and at last the Pilgrims entered the "Cape Harbor" and made their first landing near Provincetown on November 11, 1620. They had their first encounter with the native inhabitants in nearby Eastham.
European settlement
Cape Cod was among the first places settled by Puritan colonists in North America. The Cape's fifteen towns developed slowly, aside from Barnstable (1639), Sandwich (1637), and Yarmouth (1639). The final town to be established on the Cape was Bourne in 1884, breaking off from Sandwich. Provincetown was a group of huts until the 18th century. A channel from Massachusetts Bay to Buzzards Bay is shown on Southack's map of 1717. The present Cape Cod Canal was slowly developed from 1870 to 1914. The federal government purchased it in 1928.
Because of early colonial settlement and intensive land use, the Cape's vegetation was depauperate and trees were scarce by the time that Henry Thoreau saw Cape Cod during his four visits over 1849 to 1857. The settlers heated by fires, and it took 10 to 20 cords (40 to 80 m3) of wood to heat a home, so they cleared most of Cape Cod of timber early on. They planted familiar crops, but these were unsuited to Cape Cod's thin, glacially derived soils. For instance, much of Eastham was planted with wheat. The settlers practiced the burning of woodlands to release nutrients into the soil. Improper and intensive farming led to erosion and the loss of topsoil. Farmers grazed their cattle on the grassy dunes of coastal Massachusetts, only to watch "in horror as the denuded sands 'walked' over richer lands, burying cultivated fields and fences." Dunes on the outer Cape became more common, and many harbors filled in with eroded soils.
By 1800, much of Cape Cod's firewood had to be transported by boat from Maine. The paucity of vegetation was worsened by the raising of merino sheep that reached its peak in New England around 1840. The early Industrial Revolution occurred through much of Massachusetts and Rhode Island, but it mostly bypassed Cape Cod due to a lack of significant waterpower in the area. The Cape developed as a large fishing and whaling center as a result, and also because of its geographic position. After 1860 and the opening of the American West, farmers abandoned agriculture on the Cape. By 1950, forests had recovered to an extent not seen since the 18th century.
Modern era
Cape Cod became a summer haven for city dwellers beginning at the end of the 19th century. Improved rail transportation made the towns of the Upper Cape, such as Bourne and Falmouth, accessible to Bostonians. At the beginning of the twentieth century, the Northeastern mercantile elite built many large, shingled "cottages" along Buzzards Bay. The relaxed summer environment offered by Cape Cod was highlighted by writers including Joseph C. Lincoln, who published novels and countless short stories about Cape Cod folks in popular magazines such as The Saturday Evening Post and the Delineator.
Guglielmo Marconi made the first transatlantic wireless transmission originating in the United States from Cape Cod, at Wellfleet. The beach below the bluffs where his station was located is now called Marconi Beach. In 1914, he began construction of a new transatlantic wireless receiver station in Chatham and a companion transmitter station in Marion. In 1920, the stations were acquired by RCA and, in 1921, Chatham began operations as a maritime radio station communicating to ships at sea using the callsign WCC. WCC supported the communications of Amelia Earhart, Howard Hughes, Admiral Byrd, and the Hindenburg. Marconi chose Chatham due to its vantage point on the Atlantic Ocean, surrounded on three sides by water. Walter Cronkite narrated a 17-minute documentary in 2005 about the history of the Chatham Station.
Much of the east-facing Atlantic seacoast of Cape Cod consists of wide, sandy beaches. In 1961, a significant portion of this coastline, already slated for housing subdivisions, was made a part of the Cape Cod National Seashore by President John F. Kennedy. It was protected from private development and preserved for public use. Large portions are open to the public, including the Marconi Site in Wellfleet. This is a park encompassing the site of the first two-way transoceanic radio transmission from the United States. (Theodore Roosevelt used Marconi's equipment for this transmission.)
The Kennedy Compound in Hyannis Port was President Kennedy's summer White House during his presidency, and the Kennedy family continues to maintain residences on the compound. President Grover Cleveland maintained a summer home in the Gray Gables section of Bourne. Other notable residents of Cape Cod have included actress Julie Harris, US Supreme Court justice Louis Brandeis, figure skater Todd Eldredge, composer and radio personality Canary Burton, and novelists Norman Mailer and Kurt Vonnegut. Influential natives included patriot James Otis, historian and writer Mercy Otis Warren, jurist Lemuel Shaw, and naval officer John Percival.
Lighthouses
Beginning in 1797, lighthouses were erected along Cape Cod to aid in navigation. Highland Light (or Cape Cod Light) is the oldest and tallest of these, and remains as one of a number of working lighthouses on Cape Cod and the Islands. Many of Cape Cod's earliest lighthouses featured a light tower that was attached directly to – and centered on the roof of – the keeper's dwelling. A stairway to the lantern room was accessible only from the top floor of the house. This came to be known as a Cape Cod style lighthouse, yet today, the only fully intact specimens are on the west coast of the United States.
