The Ossipee Corner Fire Department is an all volunteer/on call Fire/Rescue/EMS service providing emergency services for the citizens and visitors to our precinct and surrounding area. TOWN INFORMATION: Ossipee is the county seat for Carroll County and the largest town in our six-town area. It shares its name with the Ossipee Mountains, once a range of ancient volcanoes, which border it on the west. The town is a geologists dream, with portions of the volcanic "ring dike" from the Ossipee Mountains still visible. Much of the town's soil is made of fine sand and gravel, left behind by the glaciers after the last ice age. Ossipee was incorporated in 1785 after an active pre-Revolutionary War history of skirmishes between Native Americans and British settlers. Captain John Lovewell built a fort near Ossipee Lake in the early 1700's, using the foundation of a former fort which the English built in 1650 to assist the Ossipee Indians in their war against the Mohawks.
