1947 Map of Adjuntas SO

About this map

Adjuntas sits at the heart of this mid-century topographic study, positioned where the Río Cidra meets the headwaters of the Río Grande de Arecibo. The landscape is dominated by the steep ridges of the Cordillera Central, including prominent peaks such as Cerro El Gigante and Cerro Cerrate. This 1940s survey illustrates a rural interior defined by its complex drainage network, with the Río Saltillo and Río Garzas carving deep valleys through the limestone and volcanic terrain. To the southwest, the Lago Garzas reservoir serves as a major landmark within the Bosque Insular de Guilarte. Local industrial history is noted by the Adjuntas Chimney, while the broader topography is shaped by the formidable Cuchilla Juan Gonzales ridgeline, marking the divide between the northern and southern watersheds of the island.
