That much seems to be true, at least according to this neat page hosted by the Gulf of Maine Aquarium! Just listen to the introductory sentence:
Cool, still air, water the color of dried blood, and ground that trembles
beneath your feet make the bog seem an eerie place.
Sounds good to me. Time for a field trip!!! The page recounts the wild variety of plants commonly found in Maine's bogs, and continues on reassuringly:
In Maine, no human sacrifices have been uncovered, just sphagnum moss ("peat moss") for gardens and for fuel.
And then NOT so reassuringly:
Maybe Swamp Man will have something to say about that. Show up tonight at The Alehouse for a dose of his bog-stomping hard-rockin' fury when Covered In Bees play!
Mining peat for fuel on a large scale may soon present a threat to some of our fragile bogs in northern Maine.
