About this map

The Valle de Yabucoa dominates the southeastern coastline of Puerto Rico in this mid-1940s survey, revealing a landscape deeply defined by the sugar industry. The proximity of Central Roig and Central Columbia underscores the era's economic reliance on large-scale sugarcane processing. The terrain transitions sharply from the coastal valley into the high peaks of the Sierra de Cayey and the Cuchilla de Panduras, where summits like Cerro La Pandura rise above the neighboring municipios.

Settlement patterns follow the fertile alluvial lands and river valleys, with centers like Yabucoa and Maunabo established near the coast. Smaller agrarian outposts such as Colonia Laura and Limones are scattered across the landscape, connected by a network of roads that wind through the foothills. Numerous water bodies, including the Río Guayanés and the Río Maunabo, provide the vital drainage for this high-relief Caribbean topography.
