About this map

The town of Cidra serves as the focal point for this 1940s topographic survey, which details the complex interior highlands of Puerto Rico. The urban grid of the settlement is clearly delineated, showing a concentration of structures that transitions into a landscape dominated by steep ridges and winding watercourses. A significant municipal boundary separates the Municipio de Cidra and Municipio de Cayey in the southern portion of the sheet, cutting across the rugged terrain near Cerro La Guasima.

Hydrographic patterns are exceptionally detailed, featuring the headwaters and tributaries of major systems, including the Río de la Plata and the Río Bayamón. Rural life is evidenced by the Centro Comunal Nogueras and the Escuela Segunda Unidad de Bayamón, while smaller clusters like La Placita and various unnamed structures along the mountain roads highlight the mid-century settlement patterns of the region.
