The Island That Isn't an Island

In the winter of 1675, somewhere between five hundred and eleven hundred Native Americans—mostly women and children—were forced onto a windswept patch of land in Boston Harbor. They had done nothing wrong. In fact, they had done everything right by colonial standards: they had converted to Christianity, adopted English customs, and lived peacefully alongside their settler neighbors. Their reward was internment on Deer Island, where roughly half of them would die from starvation and exposure before spring arrived.

Today, Deer Island is famous for something entirely different: twelve massive egg-shaped structures that rise one hundred fifty feet into the sky, visible from boats throughout Boston Harbor. These are sludge digesters, part of the second-largest wastewater treatment plant in the United States. The facility processes sewage from forty-three cities and towns, turning human waste into something the ocean can safely receive.

The contrast is jarring. A place of mass death transformed into a place of mass waste processing. But that's Deer Island's story—layer upon layer of human desperation, institutional necessity, and eventual bureaucratic purpose, all compressed into one hundred eighty-five acres of land that isn't technically an island anymore.

How an Island Becomes a Peninsula

Deer Island stopped being an island in 1938, though it kept the name. A channel called Shirley Gut once separated it from the town of Winthrop, Massachusetts. The channel wasn't particularly wide or deep, but it was enough to make Deer Island genuinely isolated—reachable only by boat, separated from the mainland by cold Atlantic waters.

Then came the Great New England Hurricane of September 1938. This wasn't just any storm. It remains one of the most powerful and destructive hurricanes ever to strike New England, killing nearly seven hundred people and causing damage equivalent to billions in today's dollars. The storm surge and waves reshaped coastlines throughout the region.

At Shirley Gut, the hurricane did something unexpected. Instead of carving the channel deeper, as storms often do, it filled it in. Sand and debris accumulated until the water passage simply ceased to exist. When the storm cleared, Deer Island was connected to Winthrop by solid ground. An island had become a peninsula overnight.

This is rarer than you might think. Islands usually erode during hurricanes; they don't usually merge with the mainland. But barrier beaches and tidal channels exist in a constant state of flux, and sometimes a massive injection of energy pushes them in surprising directions. Shirley Gut's disappearance is a reminder that geography isn't as permanent as maps suggest.

The Praying Indians of Deer Island

To understand what happened on Deer Island in 1675, you need to understand who the "Praying Indians" were and why colonial authorities feared them so much despite their apparent loyalty.

Throughout the seventeenth century, Puritan missionaries worked to convert Native Americans to Christianity. The most famous of these missionaries was John Eliot, who learned the Algonquian language and translated the entire Bible into it—the first Bible printed in North America. Eliot established "praying towns" where converted Native Americans could live according to English customs while practicing their new faith.

These communities existed in places like Natick, Concord, Marlborough, and Grafton. The residents had given up traditional ways of life. They wore English clothes. They attended church. They built houses in the English style. Many had been Christian for decades by 1675.

Then King Philip's War erupted.

The conflict is named for Metacom, a Wampanoag leader whom the English called "King Philip." The war was devastating—proportionally, it killed more colonists than any other war in American history. Towns burned. Families were massacred. The frontier collapsed.

Colonial authorities faced a problem. They couldn't easily tell friendly Native Americans from hostile ones. The Praying Indians insisted on their loyalty, and many had genuine attachments to their English neighbors. But fear overrode trust. What if the Praying Indians were secretly helping the enemy? What if they turned against the colonists at a critical moment?

The solution was internment.

Winter on the Harbor

In the winter of 1675-1676, colonial officials forcibly removed the Praying Indians from their towns and transported them to various islands in Boston Harbor. Deer Island received the largest group—estimates range from five hundred to over a thousand people.

The conditions were catastrophic.

There was almost no shelter. The internees had been given little time to prepare, and the island offered few resources for building adequate housing. Winter in Boston Harbor is brutal even with proper preparation. Without it, exposure became a death sentence.

Food was scarce. The colonists provided minimal supplies, and the rocky island offered little opportunity for foraging or fishing in winter conditions. Starvation compounded the effects of cold.

Meanwhile, colonial authorities pressured the men from these praying communities to prove their loyalty by joining English militia units and attacking other indigenous tribes. This created an impossible situation: serve as proxy warriors against your own people, or watch your family starve on a frozen island.

About half the internees died before spring.

Some tried to escape. A medicine man named Tantamous managed to get off Deer Island, only to be recaptured later. The historical record doesn't tell us what happened to him after that, but the odds weren't good. Escape attempts were treated as confirmation of disloyalty.

Today, Native Americans return to Deer Island annually to commemorate those who died there. It's a pilgrimage to a place of ancestral suffering—similar in spirit to how Jewish communities return to concentration camp sites, or how African Americans visit locations associated with slavery. The trauma echoes through generations.

The Famine Ships

Nearly two centuries after the Praying Indians died on Deer Island, another wave of desperate people arrived.

The Great Famine struck Ireland between 1845 and 1852. A disease called late blight destroyed the potato crop, and potatoes were the primary food source for Ireland's poor. The British government's response was catastrophically inadequate—shaped by ideology, prejudice, and bureaucratic indifference. Approximately one million people died of starvation and disease. Another million emigrated.

Many of those emigrants came to Boston.

The journey itself was deadly. The ships that carried Irish emigrants were called "coffin ships" because so many passengers died en route. Conditions below decks were horrific: overcrowding, contaminated water, epidemic disease. Survivors often arrived in Boston sick, malnourished, and traumatized.

In 1847, authorities established a hospital on Deer Island to process and treat incoming immigrants. Over the following two years, approximately forty-eight hundred men, women, and children were admitted. Many recovered and went on to build new lives in America. But more than eight hundred died on the island, their journey ending just short of the promised land.

In 1850, an almshouse was built on Deer Island to house paupers—people too poor, sick, or otherwise unable to support themselves. The City of Boston administered the facility starting in 1853. It was part of a larger system of institutions designed to manage populations that society didn't quite know what to do with: the poor, the sick, the foreign, the inconvenient.

Today, a Celtic Cross stands on Deer Island near the old almshouse site, honoring the approximately eight hundred fifty Irish emigrants who died during the Famine Era. It's a memorial to people who almost made it—who survived the blight, survived the coffin ships, survived the arrival in a new country, only to die within sight of Boston.

From Almshouse to Prison

In 1896, the almshouse facilities were converted to a different purpose: incarceration. The Deer Island House of Correction became one of the short-term prisons for Suffolk County, holding people convicted of relatively minor offenses.

The prison operated for nearly a century, finally closing in 1991 when prisoners were transferred to the South Bay House of Correction on the mainland. During its operational years, Deer Island prison became part of Boston's cultural landscape—referenced in literature and remembered in stories.

Sylvia Plath mentioned Deer Island prison in both her poem "Point Shirley" and her novel The Bell Jar. Point Shirley is the tip of the Winthrop peninsula, looking out toward Deer Island. Plath's grandfather had been a caretaker there, and the landscape appeared in her work as a place where land meets sea, where boundaries blur, where institutions contain people against their will.

There's something fitting about Plath writing about Deer Island. Her work often explored confinement—the bell jar itself is a metaphor for depression as a sealed container. And Deer Island had been confining people for three hundred years: Praying Indians, Irish immigrants, prisoners. The island's geography made it a natural container, surrounded by water that served as walls.

The Strange Flu Experiment

During the 1918 influenza pandemic, something unusual happened on Deer Island. The pandemic killed more people than World War One—estimates range from fifty to one hundred million deaths worldwide. Scientists were desperate to understand how the disease spread and how it might be prevented.

At a naval facility on Deer Island, researchers conducted an experiment. Sixty-two volunteers were selected from three hundred prisoners. The volunteers were promised pardons if they survived a set of tests designed to expose them to the influenza virus.

Here's the strange part: none of the volunteers got sick.

Researchers exposed them to infected patients. They had healthy volunteers breathe air exhaled by sick people. They transferred mucus and other bodily fluids. They did everything they could think of to transmit the disease. Nothing worked.

Meanwhile, the ward doctor who supervised the experiment contracted the flu and died.

What happened? The most likely explanation is that the prisoners had already been exposed to the virus during the weeks preceding the trial. They had developed immunity without experiencing severe symptoms—or perhaps they had been mildly sick without anyone noticing. When researchers tried to infect them intentionally, their immune systems were already prepared.

This tells us something important about how pandemics work. Exposure doesn't guarantee severe illness. Some people fight off infections without ever knowing they were sick. The prisoners on Deer Island were probably already survivors before the experiment began.

Joseph Goldberger, the doctor who published the experiment's results in 1921, would later become famous for different research: proving that pellagra was caused by nutritional deficiency, not infection. His Deer Island work is a footnote, but it illustrates how little we understood about disease transmission even a century ago.

The Egg-Shaped Future

Today, two-thirds of Deer Island is occupied by the Massachusetts Water Resources Authority's wastewater treatment plant. Those twelve egg-shaped sludge digesters have become icons of the Boston Harbor skyline—strange monuments to municipal infrastructure that most people prefer not to think about.

The first sewage treatment plant was built on Deer Island in the late nineteenth century. For decades, Boston had been dumping raw sewage into the harbor. The results were predictable: beaches closed, shellfish beds contaminated, the water increasingly toxic. The treatment plant was an attempt to address a problem that cities throughout the industrial world were facing.

The facility expanded in the 1960s but became increasingly inadequate as the metropolitan area grew. By the 1980s, Boston Harbor was considered one of the dirtiest in the nation. A lawsuit forced major upgrades.

The current plant dates from the 1990s. It can process up to one point three billion gallons of wastewater per day during wet weather. The treatment process removes pollutants, kills pathogens, and produces effluent clean enough to discharge into Massachusetts Bay through a nine-and-a-half-mile outfall tunnel.

The egg-shaped digesters are where sludge gets processed. Bacteria break down organic matter in the absence of oxygen, producing methane gas that's captured and used to generate electricity. What remains is dried, treated, and turned into fertilizer pellets. It's a closed-loop system that transforms human waste into something useful.

There's poetry in this, if you're inclined to look for it. Deer Island spent centuries containing human misery—internment, immigration processing, imprisonment. Now it contains and processes human waste. The island's purpose has always been to handle what society produces but doesn't want to look at directly.

A Place for Walking

The remaining third of Deer Island is parkland, open to visitors. A hiking and biking trail circles the island, offering views of Boston Harbor, the city skyline, and Logan International Airport.

The southern tip provides some of the best land-based views of the harbor islands—the scattered archipelago that includes Spectacle Island, Georges Island, and the outer islands stretching toward the open Atlantic. Since 1996, Deer Island has been part of the Boston Harbor Islands National and State Park, a designation that protects its recreational spaces while acknowledging its historical significance.

There's a public boat dock at the southwest corner for visitors arriving by water. Trails climb the island's escarpments, including a high point near the water tower that's become popular for planespotting. Logan Airport's runways point toward the harbor, and planes pass close overhead—close enough to read the airline logos, close enough to feel the rumble of engines.

A lighthouse stands just offshore. The original was built in 1890; a modern tower replaced it in 1984. It's a working navigation aid, guiding vessels through the busy harbor approaches, flashing its signal across water that once separated an island from the mainland until a hurricane decided otherwise.

Layers of Memory

In June 2015, a child's body was found on Deer Island. She was eventually identified as Bella Bond, a two-and-a-half-year-old girl from Boston. The discovery sparked a massive investigation and public outpouring of grief.

It was another layer added to an already complicated place. Deer Island keeps accumulating stories—some historical, some recent, all connected by the simple fact of geography. The land remains even as its purposes change.

The Praying Indians who died in 1675 couldn't have imagined a wastewater treatment plant. The Irish immigrants who arrived in 1847 couldn't have imagined airplane spotters photographing jets overhead. The prisoners who participated in flu experiments couldn't have imagined the island becoming a recreational destination.

But all of them knew Deer Island as a place apart. An island—even one that became a peninsula—creates natural separation. You're either on it or off it. The water (or what used to be water) defines a boundary.

That sense of apartness made Deer Island useful for containing people. It made it useful for processing sewage. It makes it useful today for escaping the city while remaining technically within it.

Walk the trails on a clear day, and you can see the whole sweep of Boston Harbor laid out before you. The city rises to the west. The ocean stretches east. Planes descend toward runways. Boats trace paths toward the outer islands. And beneath your feet, machines process the endless flow of what the city no longer needs.

Deer Island keeps working, as it has for centuries. The purposes change. The land endures.
