About this map

The Faro de Cabo San Juan stands as a primary landmark on this 1952 survey, marking the northeastern tip of the Puerto Rican mainland overlooking the Pasaje de San Juan. The map details a complex archipelago of cays and islands extending eastward into the Atlantic Ocean, including the prominent Cayo Icacos and the scattered islets of La Cordillera. These small landmasses, such as Cayo Lobos and Cayo de Diablo, reveal a maritime landscape defined by shallow reefs and isolated outcrops.

Inland from the coast, Laguna Grande and the surrounding Cabezas de San Juan terrain indicate a region of coastal wetlands and sandy reaches like Playa Canalejo. Further south, larger islands like Isla Palominos and its smaller neighbor Isla Palominitos are charted alongside Isla de Ramos in the Sonda de Vieques, providing a technical view of the navigation hazards and coastal geography before modern developments changed the shoreline.
