Hockomock Swamp (Bridgewater Triangle)

During King Philip's War in the 1670s the swamp served as a Wampanoag stronghold — a natural fortress of twisting waterways from which Metacomet, called King Philip by the English, launched attacks on nearby settlements. Through the eighteenth and nineteenth centuries, Euro-American owners judged the land worthless and tried repeatedly to drain it; Easton's Reverend William L. Chaffin was among the few early voices for letting it be.

The drainage mostly failed, which is why anything remains to file reports about. Today the core is the Hockomock Swamp Wildlife Management Area, run by MassWildlife, holding at least thirteen rare or endangered species. Route 24 and Route 138 cross it; an old railroad bed runs through. What the engineers could not fix, the cryptozoologists eventually catalogued.

In the 1970s cryptozoologist Loren Coleman coined the term "Bridgewater Triangle" for an area of about 200 square miles — Abington south to Freetown, west to Rehoboth — with the Hockomock at its center, and described it in his 1983 book Mysterious America. Christopher Balzano's 2008 Ghosts of the Bridgewater Triangle expanded the file, and researcher Christopher Pittman has logged reports since 1996.

The claims ledger is eclectic even by swamp standards: giant red-eyed black dogs, phantom panthers, Bigfoot-type figures, thunderbird-sized birds, UFOs and disembodied lights, cattle mutilations, a vanishing hitchhiker. The single most common report Pittman receives is unglamorous and consistent — hikers and fishermen with no knowledge of the legend describing the strong feeling of being watched. "I just know where it happened before they say anything," he has said.

The file's most cited sighting belongs to a named officer. In 1971 a Norton police sergeant driving Winter Street toward Easton reported, near the rise locals call Bird Hill, a winged creature enormous enough to qualify as a thunderbird in the legend ledger. Subsequent decades added lesser claims in the same categories — lights over the water, dogs that do not match the local breeds, figures along the roads that cross the swamp after dark.

The Boston Globe's survey of the swamp in 2005 found the old fear intact but the register changed: where Puritans filed devils, modern witnesses file cryptids and UFOs. Same swamp, updated taxonomy.

Nothing about the Hockomock requires believing any of it. The state manages it as habitat, paddlers work its rivers in daylight, and the watched-feeling reports keep arriving from people who have never heard the word Hockomock. Nine thousand years of artifacts, one war, one deity of death, two centuries of failed drainage and fifty years of filed reports: the dossier keeps the swamp's two oldest names side by side — the one that means spirits, and the one that means devil.
