About this map

Great Chebeague Island and its surrounding archipelago define this maritime landscape in Casco Bay during the mid-twentieth century. The map details the intricate shoreline of the South Harpswell peninsula, where State Route 123 terminates near the historic landing points of Potts Harbor. Evidence of coastal navigation and defense is clear, with the Observation Tower on Jewell Island and the isolated Halfway Rock light station marking the approach from the Atlantic Ocean.

The island communities are well-documented, showing established settlements like Littlefield and various maritime infrastructure such as Jenks Landing and Cliff Island Landing. Smaller landforms like Junk of Pork and Whaleboat Island punctuate the deep waters of Broad Sound and Luckse Sound. This survey captures the region just as modern photogrammetric updates were being integrated, preserving the placement of local landmarks like the Golf Course and numerous small island cemeteries.
