About this map

The Valle de Yabucoa unfolds along the southeastern coast of Puerto Rico in this mid-1940s survey, revealing a landscape defined by industrial agriculture and coastal trade. The influence of the sugar industry is evident at the Central Roig and nearby Colonia Monserrate, where the fertile plains meet a complex network of waterways like the Río Guayanés and the Zanja de Barra. The shoreline is heavily articulated with prominent landmarks such as Punta Guayanés and the sheltered waters of Puerto Yabucoa.

Further north, the transition into the Humacao district is marked by the Río Humacao and the coastal heights of Morro de Humacao. The interior terrain rises sharply toward Cerro Santa Elena, overlooking the small seaside settlement of Playa de Guayanés. This documentation captures the infrastructure of the sugar-producing regions before modern industrial shifts altered the traditional plantation layouts and rural settlement patterns of the coast.
