About this map

Fort Devens dominates the western landscape of this Middlesex County area, bordering the busy rail hub of Ayer. During the late 1930s, this region was a complex mix of military installations, academic institutions, and quiet agricultural life. To the north, the Groton School and its nearby Groton School Pond sit just outside the main Groton settlement, while the center of the sheet reveals a series of large water bodies including Knops Pond and Sandy Pond.

Industry and local heritage are clearly marked by features such as Plow Shop Pond and the Shaker Village located near the boundary of Middlesex Co and Worcester Co. The infrastructure of the era is evident in the sprawling tracks of the Boston and Maine RR, which connect settlements like Pingryville and Littleton. Notable landmarks like the Rural Home and US Quarantine near Mill Pond offer specific points of interest for genealogists and local historians.
