1960 Map of Isabela

About this map

Isabela anchors this coastline of northwestern Puerto Rico, where the land drops sharply from the inland barrios toward the Atlantic Ocean. The survey highlights the municipal boundary between Isabela and Aguadilla, illustrating a landscape transitioning from the coastal lowlands of Bajura to the elevated military grounds of Ramey Air Force Base in the west. A specialized infrastructure detail, the Tunel de Acueducto, cuts through the terrain near the coastal points of Punta Jacinto and Foso Jacinto. The map documents the residential patterns of several barrios, including Maleza Alta, Guayabos, and Jobos, providing a detailed look at the island's mid-century rural and urban organization before later modern expansion changed the character of these traditional settlements.
