Pocomoonshine Lake Monster
Also known as Poco, Chain Lake Snake, Monster of Pocomoonshine Lake
A 30- to 60-foot serpent said to haunt remote Pocomoonshine Lake in eastern Maine, first reported in 1882 when it supposedly left a huge trail on land.
Pocomoonshine Lake lies in the forest of Washington County, in far eastern Maine near the town of Princeton, well off the usual tourist routes. Local legend says that a huge serpent nicknamed Poco lives there. Estimates of its length range from about 30 to 60 feet, and a few stories have it crossing the land to neighboring lakes.
The earliest documentation comes from 1882. According to Travel Maine, the state’s tourism site, a sawmill owner named Sewell Quimby confirmed seeing a trail on land three to four feet wide and almost three feet deep in places, and the creature was said to have crossed to Crawford Lake. Writer Earl Brechlin, in an Islandport Press feature, notes that in the same year a letter in a Machias newspaper tried to refute the existence of the “Chain Lake Snake” after repeated reports of long, curving tracks on land. As with many such stories, no photographs exist. Maine Boats magazine adds that Quimby later denied his report.
Popular retellings connect the monster to a much older story of a battle on the lake between figures from Algonquian-speaking traditions, in which one combatant is transformed into a giant serpent; one tourism source renders a Native name for the lake, Nesiek, as “muddy from the great fight.” The details differ from one teller to another, and none of the sources consulted traces the story to a Passamaquoddy or other Wabanaki storyteller, so these origins should be treated as unverified; the living traditions of the Wabanaki peoples are best heard in their own voices.
No one has been reported attacked, and an informal survey of lake-country businesses by Maine Boats found no significant recent sightings. Skeptics suggest oversized otters, large eels, an escaped exotic snake, drifting vegetation, or just light playing on the water. The lake sits on a list of North American lake monsters on Wikipedia, and Poco remains one of Maine’s quieter, more rural monsters.
What witnesses describe
A snake-like animal 30 to 60 feet long, reported both in the water and as a track or trail on land. The 1882 land trail was said to be three to four feet wide and almost three feet deep in places.
Where and when it’s seen
Pocomoonshine Lake, a small remote lake near Princeton and Alexander in Washington County, Maine, and the forest between it and nearby lakes such as Crawford Lake. The best-documented reports are from the 1880s.
Notable sightings
- 1882Quimby and the land trail Pocomoonshine Lake, Maine
Sawmill owner Sewell Quimby reportedly confirmed seeing a trail three to four feet wide and nearly three feet deep, taken as evidence of a very large serpent crossing from the lake to Crawford Lake. He is said to have denied the report later.
- 1882A Machias letter on the “Chain Lake Snake” Machias, Maine
A letter printed in a Machias newspaper tried to explain away the serpent after several witnesses reported long, curving tracks on land. It is the earliest newspaper mention that the sources consulted identify.
What could explain it?
- Large known animals: otters swimming in a line, big eels or sturgeon-like fish, or a moose or beaver trail can create the impression of a long, undulating body.
- A discredited witness: Quimby reportedly withdrew his claim, and the 1882 letter writer argued for ordinary explanations.
- Aquatic vegetation and light on the water: floating plant mats or wind streaks can look like humps.
- Thin early evidence: the record rests on one uncorroborated witness and one brief newspaper letter, and later writers added details such as exact lengths that cannot be traced to those early sources.
Legend, culture and tourism
Poco is featured in Maine tourism material and in regional books and magazine features on Maine’s hidden monsters, and appears on Wikipedia’s list of lake monsters. It has no festival or statue; its charm is the remoteness of the lake itself.
Places to visit
Remote Washington County lake described by Travel Maine as the home of the Pocomoonshine monster; roads in the area are rural and not always signed.
