About this map

The Río de la Plata carves a deep, winding course through the central highlands of Puerto Rico, anchoring a landscape where agricultural traditions met mid-century modernization. In the late 1950s, the urban centers of Comerio and Cidra served as essential hubs for the surrounding barrios. The presence of the Escuela Vocacional Eugenio María de Hostos and the Escuela Superior de Comerío points to a period of significant educational investment in the mountain communities.

Industry and infrastructure are evidenced by the Lago de Cidra reservoir and the Central Cayey facility in the southeast corner. The terrain is defined by numerous named peaks like Cerro Magueyes and Cerro Gordo, while a dense network of creeks, including Quebrada Higuero and Quebrada Toita, drain the steep slopes. Small settlements such as Sumidero and Nogueras highlight the localized nature of mountain life before major highway expansions shifted the region's connectivity.
