1950 Map of Sebec Lake

About this map

The slate industry and rail transport define this 1950 portrait of Piscataquis County, where the Monson town center serves as a hub for local extraction. Numerous slate workings, including Kineo Quarry and several Hillside Quarry sites, are concentrated near the Monson Cem, illustrating the industrial footprint of the era. To the north and east, the landscape shifts to a network of sporting camps and landings along the waters of Onawa Lake and Sebec Lake, accessible via the Canadian Pacific railroad. The rugged interior is traversed by the Appalachian Trail, which winds past Boarstone Mountain and Barren Mountain. Historical researchers will find significant detail in the various camps such as St Regis Depot Camp and Camp Twelve, alongside family-named landmarks like Goodell Corner and Earley Landing that mark the transition from industrial town to remote wilderness.
