1947 Map of Rio Grande

About this map

Agricultural colonies and coastal wetlands define this northern Puerto Rican landscape during the late 1940s. The settlement of Río Grande sits inland, south of the extensive Ciénaga La Picúa and the waters of Ensenada Comezón. The map documents a transition from the marshy lowlands of Medianía Baja to the higher elevations of Mameyes II, punctuated by numerous named agricultural estates such as Colonia Mini Mini and Colonia Fortuna.
